Leg strength and incidence of heart failure in patients with acute coronary syndrome. Eur J Prev Cardiol 2024; 31:834-842. [PMID: 38150177 DOI: 10.1093/eurjpc/zwad406] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 12/17/2023] [Accepted: 12/18/2023] [Indexed: 12/28/2023]
Abstract
AIMS The risk of developing heart failure (HF) after acute coronary syndrome (ACS) remains high. It is unclear whether skeletal muscle strength, in addition to existing risk factors, is a predictor for developing HF after ACS. We aimed to clarify the relationship between quadriceps isometric strength (QIS), a skeletal muscle strength indicator, and the risk of developing HF in patients with ACS. METHODS AND RESULTS We included 1053 patients with ACS without a prior HF or complications of HF during hospitalization. The median (interquartile range) age was 67 (57-74) years. The patients were classified into two groups-high and low QIS-using the sex-specific median QIS. The endpoint was HF admissions. During a mean follow-up period of 4.4 ± 3.7 years, 75 (7.1%) HF admissions were observed. After multivariate adjustment, a high QIS was associated with a lower risk of HF [hazard ratio: 0.52, 95% confidence interval (CI): 0.32-0.87]. Hazard ratio (95% CI) per 5% body weight increment increase of QIS for HF incidents was 0.87 (0.80-0.95). Even when competing risks of death were taken into account, the results did not change. The inclusion of QIS was associated with increases in net reclassification improvement (0.26; 95% CI: 0.002-0.52) and an integrated discrimination index (0.01; 95% CI: 0.004-0.02) for HF. CONCLUSION The present study showed that a higher level of QIS was strongly associated with a lower risk of developing HF after ACS. These findings suggest that skeletal muscle strength could be one of the factors contributing to the risk of developing HF after ACS.

Prevalence and relevance of cachexia as diagnosed by two different definitions in patients undergoing hemodialysis: A retrospective and exploratory study. Arch Gerontol Geriatr 2024; 124:105447. [PMID: 38692154 DOI: 10.1016/j.archger.2024.105447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Revised: 04/08/2024] [Accepted: 04/14/2024] [Indexed: 05/03/2024]
Abstract
OBJECTIVE Cachexia is present in various chronic diseases and is associated with decreased quality of life and increased risk of morbidity and mortality. However, evidence regarding the association of cachexia with prognosis in patients undergoing hemodialysis is limited. We assessed cachexia using two definitions and compared prevalence, functional impairment, and prognostic impact in patients undergoing hemodialysis. METHODS We enrolled outpatients undergoing hemodialysis at two centers retrospectively. We assessed cachexia using the conventional cachexia (Evans' criteria) and the Asian Working Group for Cachexia (AWGC) criteria. The study examined all-cause mortality and functional status (Clinical Frailty Scale and short physical performance battery). We used Cox proportional hazards model to examine the association with prognosis, and logistic regression analysis to examine the association with functional impairment. RESULTS Among 367 patients (mean age, 67 years; 63 % male), cachexia prevalence, as defined by Evans' criteria and AWGC, was 21.3 % and 35.2 %, respectively. Cachexia as defined by Evans' criteria was associated with an increased risk of all-cause mortality (hazard ratio [HR], 95 % confidence interval [CI]: 1.81, 1.02-3.23). Also, cachexia as defined by AWGC criteria showed suggestive association with increasing mortality (HR, 95 % CI: 1.56, 0.90-2.70). Similar results were seen between cachexia and functional impairment. CONCLUSIONS Among patients on hemodialysis, cachexia was highly prevalent and was associated with poor prognosis and functional impairment. Detecting cachexia in earlier stages may be useful for risk stratification in this population.

Cancer history and physical function in patients with cardiovascular disease. Heart Vessels 2024:10.1007/s00380-024-02379-5. [PMID: 38578318 DOI: 10.1007/s00380-024-02379-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 02/21/2024] [Indexed: 04/06/2024]
Abstract
Both cancer and cardiovascular disease (CVD) cause skeletal muscle mass loss, thereby increasing the likelihood of a poor prognosis. We investigated the association between cancer history and physical function and their combined association with prognosis in patients with CVD. We retrospectively reviewed 3,796 patients with CVD (median age: 70 years; interquartile range [IQR]: 61-77 years) who had undergone physical function tests (gait speed and 6-minute walk distance [6MWD]) at discharge. We performed multiple linear regression analyses to assess potential associations between cancer history and physical function. Moreover, Kaplan-Meier curves and Cox regression analyses were used to evaluate prognostic associations in four groups of patients categorized by the absence or presence of cancer history and of high or low physical function. Multiple regression analyses showed that cancer history was significantly and independently associated with a lower gait speed and 6MWD performance. A total of 610 deaths occurred during the follow-up period (median: 3.1 years; IQR: 1.4-5.4 years). The coexistence of low physical function and cancer history in patients with CVD was associated with a significantly higher mortality risk, even after adjusting for covariates (cancer history/low gait speed, hazard ratio [HR]: 1.93, P < 0.001; and cancer history/low 6MWD, HR: 1.61, P = 0.002). Cancer history is associated with low physical function in patients with CVD, and the combination of both factors is associated with a poor prognosis.

The Association between the Level of Ankle-Brachial Index and the Risk of Poor Physical Function in Patients with Cardiovascular Disease. J Atheroscler Thromb 2024; 31:419-428. [PMID: 38044086 PMCID: PMC10999722 DOI: 10.5551/jat.64531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 09/26/2023] [Indexed: 12/05/2023] Open
Abstract
AIMS The progression of atherosclerosis and decline in physical function are poor prognostic factors in patients with cardiovascular disease (CVD). The ankle-brachial index (ABI) is a widely used indicator of the degree of progression of atherosclerosis, which may be used to identify patients with CVD who are at risk of poor physical function. This study examined the association between ABI and poor physical function in patients with CVD. METHODS We reviewed the data of patients with CVD who completed the ABI assessment and physical function tests (6-min walking distance, gait speed, quadriceps isometric strength, and short physical performance battery). Patients were divided into five categories according to the level of ABI, and the association between ABI and poor physical function was examined using multiple logistic regression analysis. Additionally, restricted cubic splines were used to examine the nonlinear association between ABI and physical function. RESULTS A total of 2982 patients (median [interquartile range] age: 71[62-78] years, 65.8% males) were included in this study. Using an ABI range of 1.11-1.20 as a reference, logistic regression analysis showed that ABI ≤ 1.10 was associated with poor physical function. The restricted cubic spline analysis showed that all physical functions increased with an increase in ABI level. The increase in physical function plateaued at an ABI level of approximately 1.1. CONCLUSIONS ABI may be used to identify patients with poor physical function. ABI levels below 1.1 are potentially associated with poor physical function in patients with CVD.

Clinical Impact of Improvement in Sarcopenia through Cardiac Rehabilitation in Patients with Heart Failure. J Am Med Dir Assoc 2024; 25:514-520.e2. [PMID: 38182121 DOI: 10.1016/j.jamda.2023.10.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 10/14/2023] [Accepted: 10/16/2023] [Indexed: 01/07/2024]
Abstract
OBJECTIVES Sarcopenia in patients with heart failure (HF) is associated with poor prognosis. Cardiac rehabilitation (CR) decreases the incidence of adverse events in patients with HF. However, the clinical implications of improving sarcopenia status through CR remain unclear. This study investigated the relationship between the changes in sarcopenia status in patients with HF undergoing outpatient CR and the risk of mortality and adverse events. DESIGN This was a retrospective cohort study of patients hospitalized at the Kitasato University Hospital Cardiovascular Center for the treatment of HF between January 2007 and December 2020. SETTING AND PARTICIPANTS Patients with HF whose sarcopenia status was assessed at hospital discharge and following at least 3 months of outpatient CR were included. Based on the sarcopenia status, all patients were divided into 3 groups: patients without sarcopenia at discharge (ie, robust), patients with sarcopenia at discharge but no sarcopenia following CR (ie, improved), and patients with sarcopenia at discharge and following CR (ie, unimproved). METHODS Cox regression analysis was used to examine the risk of all-cause death associated with the 3 sarcopenia status groups. RESULTS Of 546 patients with HF (median age: 70 years; male: 63.6%), 377 (69.0%), 54 (9.9%), and 115 (21.1%) were classified as robust, improved, and unimproved, respectively. Multivariate Cox regression analysis showed that the unimproved group had a significantly greater risk of all-cause death when compared to the robust group [hazard ratio (HR) 2.603, 95% CI 1.375-4.930, P = .004], but it did not differ from the improved group (HR 1.403, 95% CI 0.598-3.293, P = .43). CONCLUSIONS AND IMPLICATIONS No improvement in sarcopenia status in patients with HF undergoing outpatient CR was associated with a higher risk of all-cause death. Sarcopenia may be an important target to improve the prognosis of patients with HF.

Screening for sarcopenia with SARC-F in older patients hospitalized with cardiovascular disease. Eur J Cardiovasc Nurs 2024:zvae017. [PMID: 38315615 DOI: 10.1093/eurjcn/zvae017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 01/31/2024] [Accepted: 02/02/2024] [Indexed: 02/07/2024]
Abstract
OBJECTIVES SARC-F ≥ 4 points are used for detecting sarcopenia; however, finding a lower SARC-F cut-off value may lead to early detection of sarcopenia. We investigated the SARC-F score with the highest sensitivity and specificity value to identify sarcopenia in older patients with cardiovascular disease (CVD). Motor performances were also examined for each SARC-F score. METHODS This retrospective cross-sectional study examined the sensitivity and specificity of every 1-point increase in SARC-F score to predict sarcopenia. Eligible participants included patients with CVD (≥ 65 years old) who were admitted for acute CVD treatment and participated in cardiac rehabilitation. Patients completed the SARC-F questionnaire and the sarcopenia assessment. Areas under the curves (AUCs) were investigated for the ability to predict sarcopenia. Multivariable linear regression was used to compare the mean value of physical functions (e.g., Walking speed, leg strength, and 6-minute walking distance) of each SARC-F score. RESULTS A total of 1066 participants (63.8% male; median age: 78 years) were included. Sarcopenia was present in 401 patients. SARC-F cut-off ≥ 2 presented the optimal balance between sensitivity (68.3%) and specificity (55.6%) to detect sarcopenia (the AUCs = 0.658; 95% confidence interval: 0.625-0.691). Even when the patients have low scores (1-3), increasing every 1 point of SARC-F score was associated with lower physical functions, such as lower muscle strength and shorter walking distance (all p < 0.001). CONCLUSIONS SARC-F cut-off ≥ 2 was optimal for screening sarcopenia, and even a low SARC-F score is helpful in finding earlier sarcopenia and low physical function in patients with CVD.

Abstract
OBJECTIVE This study focused on routine computed tomography imaging for aortic disease management and evaluated the trajectory of skeletal muscle changes through inpatient and outpatient cardiac rehabilitation. DESIGN Prospective observational study included patients who underwent abdominal computed tomography three times (baseline, postacute care, and follow-up). The area and density of the all-abdominal and erector spine muscles and intramuscular adipose tissue were measured. A generalized linear model with patients as random effects was used to investigate skeletal muscle changes. RESULTS Thirty-nine patients completed outpatient cardiac rehabilitation, and 60 were incomplete. Skeletal muscle area significantly decreased from baseline to the follow-up period only in the incomplete rehabilitation group. Skeletal muscle density significantly decreased from baseline to postacute care and increased at the follow-up period, but only patients who completed rehabilitation showed recovery up to baseline at the follow-up period. These trajectories were more pronounced in the erector spine muscle. Intramuscular adipose tissue showed a trend of gradual increase, but only the incomplete rehabilitation group showed a significant difference from baseline to the follow-up period. CONCLUSIONS The density of skeletal muscle may reflect the most common clinical course; skeletal muscle area and intramuscular adipose tissue are unlikely to improve positively, and their maintenance seemed optimal.

Association of sarcopenia defined by different skeletal muscle mass measurements with prognosis and quality of life in older patients with heart failure. J Cardiol 2023:S0914-5087(23)00305-2. [PMID: 38135146 DOI: 10.1016/j.jjcc.2023.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 12/10/2023] [Accepted: 12/15/2023] [Indexed: 12/24/2023]
Abstract
BACKGROUND Diagnosing sarcopenia in heart failure (HF) patients is important, but how to assess skeletal muscle mass in HF patients with fluid retention is controversial. We aimed to examine the association between sarcopenia, defined by different skeletal muscle mass measurements, and clinical outcomes in older HF patients. METHODS We included 546 older HF patients (≥ 65 years) who were assessed for sarcopenia at discharge (median age 77 years, 309 males). Sarcopenia was diagnosed using grip strength, usual gait speed, and skeletal muscle mass according to international criteria. We used mid-upper arm circumference (MUAC), mid-upper arm muscle circumference (MAMC), calf circumference (CC), and skeletal muscle mass index (SMI) assessed by bioelectrical impedance analysis to assess skeletal muscle mass and defined sarcopenia in each of these measurements. Prognostic outcomes were composite events (all-cause death and HF rehospitalization) and cardiovascular disease (CVD) events (CVD death and CVD rehospitalization). Quality of life (QOL) was assessed using the 36-item Short-Form Health Survey physical functioning (SF-36PF) score. RESULTS The sarcopenia defined by MUAC [hazard ratio (HR): 2.50; 95 % confidence interval (95 % CI): 1.64-3.81; p < 0.001] or MAMC (HR: 1.98; 95 % CI: 1.35-2.92; p = 0.001) were associated with higher composite event rates than the non-sarcopenia. The sarcopenia defined by MUAC (HR: 1.88; 95 % CI: 1.25-2.83; p = 0.002) or MAMC (HR: 1.70; 95 % CI: 1.16-2.49; p = 0.007) were associated with higher CVD event rates than the non-sarcopenia. The sarcopenia defined by CC or SMI were not associated with prognoses. The sarcopenia defined by MUAC, MAMC, or CC were associated with low SF-36PF scores (all p < 0.05). CONCLUSIONS These results suggest that a diagnosis of sarcopenia based on MUAC or MAMC rather than CC or SMI reflects prognosis and QOL in older HF patients.

Abstract
BACKGROUND Patients undergoing hemodialysis (HD) have difficulty increasing their gait speed in daily life. The extent of the increase from the usual gait speed (UGS) to the maximum gait speed (MGS) is considered the reserved gait capacity (RGC). Little is known regarding the implications of RGC. This study aimed to investigate the association between RGC and all-cause mortality in patients undergoing HD. METHODS In this retrospective study, we assessed the usual and maximum 10-m walking speed of outpatients who underwent HD between October 2002 and August 2021. RGC was defined as the ratio of MGS to UGS. Patients were divided into three groups according to the tertiles of RGC (low, moderate and high). A Cox proportional hazards regression model was used to examine the association between RGC and all-cause mortality. RESULTS Of the 496 (median age 66.0 years; men 59%) participants, 186 patients died during the follow-up (incident ratio of 62.0 per 1000 person-years). The patients with moderate [hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.46-0.94] and high (HR 0.44, 95% CI 0.30-0.65) RGC had a lower risk of mortality than the low RGC group. Furthermore, even when restricted to a population with only UGS <1.0 m/s, the group with high RGC still had a lower risk of mortality than those with low RGC (HR 0.55, 95% CI 0.33-0.94). CONCLUSIONS Lower RGC was independently associated with an increased risk of all-cause mortality among patients on HD; high RGC had a survival advantage even with a slow UGS.

Abstract
OBJECTIVE The Short Physical Performance Battery (SPPB) is recommended for evaluating physical performance in patients on hemodialysis (HD). However, the association between SPPB score and long-term health outcomes in these patients remains unclear. We examined the association of SPPB score with all-cause mortality, all-cause hospitalization, and cardiovascular hospitalization in patients on HD. DESIGN AND METHODS This retrospective cohort study included 326 patients (median age, 68 years; 62% men) who received outpatient HD therapy. These patients were divided into 2 SPPB groups: low (SPPB ≤9) and high (SPPB >9). We investigated the association of SPPB score and their change over time with health outcomes using Cox regression analysis. RESULTS Low SPPB score was associated with a higher risk for all-cause mortality (hazard ratio [HR]: 3.19, 95% confidence interval [95% CI]: 1.89-5.38), all-cause hospitalization (HR: 2.01, 95% CI: 1.44-2.82), and cardiovascular hospitalization (HR: 2.20, 95% CI: 1.45-3.35). Additionally, change in SPPB score over 1 year was associated with health outcomes. CONCLUSIONS Lower SPPB score was significantly associated with a higher risk for all-cause mortality, all-cause hospitalization, and cardiovascular hospitalization. The SPPB may be a valuable indicator for risk stratification in patients on HD. Additionally, preventive treatments may be an effective management strategy in limiting the high mortality and hospitalization rates in patients with decreased SPPB score.

Abstract
BACKGROUND Frailty is a state of increased vulnerability owing to adverse health outcomes and is recognized as a multidimensional construct. There is limited evidence on the association between multiple domains of frailty and the risk of adverse events in patients undergoing hemodialysis. We aimed to report on the prevalence, degree of overlap, and prognostic impact of multiple frailty domains in older patients undergoing hemodialysis. METHODS We retrospectively enrolled outpatients (aged ≥60 years) undergoing hemodialysis at two dialysis centers in Japan. The physical domain of frailty was defined as slow gait speed and low handgrip strength. The psychological and social domains of frailty were defined using a questionnaire to assess depressive symptoms and define social frailty status. The outcomes were all-cause mortality, all-cause hospitalization, and cardiovascular hospitalization. Cox proportional hazard and negative binomial models were used to examine these associations. RESULTS Among the 344 older patients (mean age, 72 years; male, 61%), 15.4% had an overlap in all three domains. Patients with a higher number of frailty domains had a higher risk of all-cause mortality, all-cause hospitalization, and cardiovascular hospitalization (P for trend = 0.001, 0.001, and 0.08, respectively). CONCLUSIONS These results suggest that multiple-domain assessment of frailty is an important strategy to prevent adverse events in patients requiring hemodialysis.

Abstract
BACKGROUND Sarcopenia is associated with risks of various adverse outcomes, and the assessment of skeletal muscle mass is necessary for its diagnosis. However, heart failure (HF) is a syndrome characterised by fluid retention, which affects muscle mass measurements. Different measurement methods have been reported to have different prognostic implications. We investigated the association between skeletal muscle mass metrics measured with the use of bioelectrical impedance analysis (BIA) and anthropometric measures and prognosis in patients with HF. METHODS The findings of 869 consecutive patients with HF were reviewed. We investigated the skeletal muscle mass index (SMI) measured with the use of BIA, the mid-upper arm circumference (MUAC), the arm muscle circumference (AMC), and the calf circumference (CC), and the patients were divided into 3 groups according to the sex-specific tertiles of the skeletal muscle mass metrics. The end points were all-cause death and readmission due to HF. RESULTS The high MUAC and AMC groups showed significantly better prognoses than their respective low groups (combined events: high MUAC group hazard ratio [HR] 0.559, 95% confidence interval [CI] 0.395-0.789 [P < 0.01]; high AMC group HR 0.505, 95% CI 0.359-0.710 [P < 0.01]), although high SMI and high CC were not associated with better prognoses. CONCLUSIONS Among patients with HF, MUAC and AMC are more associated with prognosis than SMI and CC, which are recommended in preexisting sarcopenia guidelines. MUAC and AMC may also be useful measures in sarcopenia assessments.

Abstract
BACKGROUND The effectiveness of acute-phase cardiovascular rehabilitation (CR) in intensive care settings remains unclear in patients with cardiovascular disease (CVD). This study aimed to investigate the trends and outcomes of acute-phase CR in the intensive care unit (ICU) for patients with CVD, including in-hospital and long-term clinical outcomes. METHOD This retrospective cohort study reviewed a total of 1,948 consecutive patients who were admitted to a tertiary academic ICU for CVD treatment and underwent CR during hospitalisation. The endpoints of this study were the following: in-hospital outcomes: probabilities of walking independence and returning home; and long-term outcomes: clinical events 5 years following hospital discharge, including all-cause readmission or cardiovascular events. It evaluated the associations of CR implementation during ICU treatment (ICU-CR) with in-hospital and long-term outcomes using propensity score-matched analysis. RESULTS Among the participants, 1,092 received ICU-CR, the rate of which tended to increase with year trend (p for trend <0.001). After propensity score matching, 758 patients were included for analysis (pairs of n=379 ICU-CR and non-ICU-CR). ICU-CR was significantly associated with higher probabilities of walking independence (rate ratio, 2.04; 95% CI 1.77-2.36) and returning home (rate ratio, 1.22; 95% CI 1.05-1.41). These associations were consistently observed in subgroups aged >65 years, after surgery, emergency, and prolonged ICU stay. ICU-CR showed significantly lower incidences of all-cause (HR 0.71; 95% CI 0.56-0.89) and cardiovascular events (HR 0.69; 95% CI 0.50-0.95) than non-ICU-CR. CONCLUSIONS The implementation of acute-phase CR in ICU increased with year trend, and is considered beneficial to improving in-hospital and long-term outcomes in patients with CVD and various subgroups.

Abstract
AIM Patients with heart failure (HF) frequently experience decreased physical function, including walking speed. Slower walking speed is associated with poorer prognosis. However, most of these reports focused on patients with stable HF, and the relationship between walking speed in acute phase and clinical outcomes is unclear. Therefore, we aimed to investigate the associations between walking speed early after admission and clinical events in patients with acute decompensated HF (ADHF). METHODS AND RESULTS We reviewed consecutive 1391 patients admitted due to ADHF. We measured walking speed the first time to walk on the ward more than 10 m after admission, and the speed within four days after admission was included in this study. The primary outcome was combined events (all-cause death and/or readmission due to HF). The follow-up period was up to one year from the discharge. The study population had a median age of 74 years (interquartile range [IQR]: 65-80 years), and 35.9% of patients were females. The median walking speed was 0.70 m/s (IQR: 0.54-0.88 m/s). Combined events occurred in 429 (30.8%) patients. Faster walking speed was independently associated with lower rate of combined events (adjusted hazard ratio per 0.1 m/s increasing: 0.951, 95% confidence interval:0.912-0.992). CONCLUSION Faster walking speed within four days after admission was associated with favourable clinical outcomes in patients with ADHF. The results suggest that measuring walking speed in acute phase is useful for earlier risk stratification.

Effects of anthropometric changes on hospitalization and mortality among patients on hemodialysis. J Nephrol 2023; 36:1983-1990. [PMID: 37358730 DOI: 10.1007/s40620-023-01678-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Accepted: 05/08/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Low values for anthropometric indicators are risk factors for adverse clinical outcomes among patients on hemodialysis. Nonetheless, little is known about the association between the trajectory of anthropometric indicators and prognosis. We examined the association between a one-year change in anthropometric indicators and hospitalization and mortality in patients undergoing hemodialysis. METHODS This retrospective cohort study collected data on five anthropometric indicators from patients undergoing maintenance hemodialysis: body mass index, mid-upper arm circumference, triceps skinfold, mid-arm muscle circumference, and calf circumference. We calculated their trajectories over one year. The outcomes were all-cause death and the number of all-cause hospitalizations. Negative binomial regressions were used to examine these associations. RESULTS We included 283 patients (mean age, 67.3 years; 60.4% males). During the follow-up period (median, 2.7 years), 30 deaths and 200 hospitalizations occurred. Body mass index (incident rate ratio [IRR]: 0.87; 95% confidence interval [CI] 0.85-0.90), mid-upper arm circumference (IRR: 0.94; 95% CI 0.88-0.99), triceps skinfold (IRR: 0.92; 95% CI 0.84-0.99), and mid-arm muscle circumference (IRR: 0.99; 95% CI 0.98-0.99) increases over one year were associated with a lower risk of all-cause hospitalizations and death regardless of their value at any one point in time. However, the calf circumference trajectory was not associated with clinical events (IRR: 0.94; 95% CI 0.83-1.07). CONCLUSIONS Body mass index, mid-upper arm circumference, triceps skinfold, and mid-arm muscle circumference trajectories were independently associated with clinical events. Routinely assessing these simple measures in clinical practice may provide additional prognostic information for managing patients undergoing hemodialysis.

Association between Physical Frailty and Sleep Disturbances among Patients on Hemodialysis: A Cross-Sectional Study. Nephron Clin Pract 2023; 148:152-159. [PMID: 37586328 DOI: 10.1159/000533418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Accepted: 07/11/2023] [Indexed: 08/18/2023] Open
Abstract
INTRODUCTION Among patients on hemodialysis (HD), physical frailty and sleep disturbances are not only common but also associated with adverse outcomes. The aim of this study was to evaluate the association between physical frailty and sleep disturbances in patients on HD. METHODS This cross-sectional study was conducted from June 2017 to March 2021, with outpatients receiving HD 3 times a week at two dialysis facilities in Japan. Sleep disturbances were identified with the Athens Insomnia Scale (AIS). Physical frailty was defined using the Fried Frailty Phenotype. Patients were classified as "non-frailty (number of frailty components: 0-2)" or "frailty (3-5)." We examined the association of sleep disturbances with physical frailty and its components by performing a logistic regression analysis. RESULTS We analyzed 360 patients (mean age 65.6 years; 62% men). Eighty-one patients (23%) were classified into the group with frailty, and the mean AIS score was 5.2 ± 4.2 points. After adjusting for clinical characteristics, increasing the AIS score per 1 point was associated with higher odds of physical frailty (odds ratio, 1.12; 95% confidence interval, 1.05-1.20; p < 0.01). As for the frailty components, exhaustion, low physical activity, and weak grip strength showed an association with sleep disturbances (all p < 0.05). CONCLUSIONS Sleep disturbances were independently associated with physical frailty in patients on HD. Future studies are warranted to investigate the causality between physical frailty and sleep disturbances in this population.

Prognostic value of liver damage assessed through direct bilirubin levels and skeletal muscle weakness in patients with heart failure. Heart Lung 2023; 60:87-94. [PMID: 36934475 DOI: 10.1016/j.hrtlng.2023.03.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 02/21/2023] [Accepted: 03/04/2023] [Indexed: 03/19/2023]
Abstract
BACKGROUND Patients with heart failure (HF) often exhibit signs of liver dysfunction such as high bilirubin concentrations, leading to physical dysfunction and poor prognosis. Nevertheless, the relationship between direct bilirubin (DB), a fractionated form of total bilirubin, and dynapenia remains unclear, as does their effect on prognosis. OBJECTIVES This study investigated the association between DB concentrations and dynapenia in patients with HF. METHODS This retrospective study included patients with HF who underwent assessments for DB concentration, and handgrip and leg strengths to evaluate dynapenia and muscle weakness, respectively. Multiple logistic regression analyses examined the associations of DB with muscle strength and dynapenia. Additionally, we examined the prognostic value of comorbid high DB concentrations (≥0.5 mg/dL) and dynapenia. The endpoint was all-cause mortality. RESULTS Of 853 inpatients, high DB was identified in 147 and dynapenia in 377 (44.2%). Multiple regression analysis revealed that high DB was independently associated with decreased muscle strength (handgrip strength, P = 0.027; leg strength, P = 0.002). After adjusting for covariates, the high DB group (odds ratio: 1.800, 95% confidence interval [CI]: 1.203-2.695, P = 0.004) had a significantly higher risk of dynapenia than the low DB group. During the follow-up period, 189 patients died (median, 1.77 years; interquartile range, 0.64-3.81 years). The risk of death was significantly higher in the high DB and dynapenia group, even after adjusting for HF severity (hazard ratio: 2.610, 95% CI: 1.680-4.051, P<0.001). CONCLUSIONS High DB is associated with muscle weakness, and when combined with dynapenia, DB predicts a poorer prognosis in patients with HF.

Abstract
OBJECTIVE Although some clinical expert guidelines recommend regular monitoring of serum albumin levels in patients undergoing maintenance hemodialysis, little is known about the serum albumin trajectory patterns over time, and it is unclear how the trajectory change before death. METHODS We performed this retrospective study using data from 421 patients receiving hemodialysis in a dialysis facility. We divided patients into died and survived groups according to whether they died during the observation period. To compare the albumin trajectories during the observation period between the died and survived groups, linear mixed-effect models and a backward timescale from the year of death or study end were used. RESULTS During the observation period (median, 5.1 years; maximum, 8.4 years), 115 patients receiving dialysis died. The serum albumin level showed steeper decline 3 years before death in the died group than in the survived group. The difference in albumin between the died and survived groups became apparent 3 years before death (difference, 0.08 g/dL; 95% confidence interval, 0.00-0.15 g/dL; P = .04), and the difference widened over time (difference at 1 year before death, 0.24 g/dL; 95% confidence interval, 0.14-0.33 g/dL; P < .001). Furthermore, in an analysis of albumin trajectories according to cause of death, the albumin level showed a downward trend regardless of the cause of death. CONCLUSION The serum albumin trajectory differed between patients undergoing hemodialysis who died and who survived, supporting the importance of monitoring the albumin trajectory in clinical practice.

Abstract
BACKGROUND Frailty is associated with adverse outcomes in patients undergoing hemodialysis (HD). However, no study has used various frailty assessments in patients on HD to examine their association with clinical events. In this study, we investigated the association between clinical events and six frailty scales. METHODS Outpatients who underwent HD between 2018 and 2020 were retrospectively enrolled. Frailty was defined using the Fried Frailty Phenotype, Study of Osteoporotic Fractures (SOF) Index, Short Physical Performance Battery (SPPB), Frail Screening Index, FRAIL scale and Clinical Frailty Scale. Outcomes were clinical events, including a composite of multiple (i.e. recurrent) all-cause hospitalizations, fractures and/or all-cause mortality. The association of clinical events and the frailty scales were investigated using negative binomial regression analysis. RESULTS Fried Frailty Phenotype [incident rate ratio (IRR), 1.62; 95% confidence interval (CI), 1.49-1.76], SOF Index (IRR, 1.42; 95% CI, 1.10-1.83), SPPB (IRR, 1.79; 95% CI, 1.11-2.88) and Clinical Frailty Scale (IRR, 1.65; 95% CI, 1.04-2.61) were significantly associated with clinical events. However, Frail Screening Index (IRR, 1.38; 95% CI, 0.60-3.18) and FRAIL scale (IRR, 1.30; 95% CI, 0.88-1.92) showed no significant association with clinical events. CONCLUSIONS Objective frailty assessments (SPPB) and medical staff impression-based frailty (Clinical Frailty Scale) may be useful prognostic predictors for patients on HD. Questionnaire-based frailty assessment should be carefully considered when used as a measurement of frailty.

Abstract
AIMS Impairment in activities of daily living (ADL) is an independent predictor of poor prognosis in older patients. Nevertheless, the effects of instrumental ADL (IADL) frequency on prognosis in older patients with cardiovascular disease (CVD) are unclear. We investigate the associations between IADL frequency and all-cause mortality and hospital readmission due to cardiovascular events in older patients with CVD. METHODS AND RESULTS A total of 638 consecutive outpatients ≥65 years old with CVD were enrolled. A questionnaire, including Frenchay Activities Index (FAI) parameters, was used to determine IADL frequency at the start of the study as the baseline observation. The primary endpoint was all-cause mortality, and the secondary endpoint was readmission for cardiovascular events. We examined the relationship between IADL frequency and each endpoint. Among the 632 patients evaluated {median age 74.0 [interquartile range (IQR) 70.0-78.0] years; 439 males}, there were 39 deaths and 105 cardiovascular events during the median follow-up period of 4.0 (IQR, 2.3-4.0) years. After adjusting for clinical confounding factors, the hazard ratios for all-cause mortality and cardiovascular events in the FAI points were 0.957 [95% confidence interval (CI), 0.920-0.996] and 0.973 (95% CI, 0.950-0.997), respectively. CONCLUSION A higher IADL frequency was independently associated with better outcomes in older patients with CVD, suggesting that the preservation of instrumental activities should be focused on as the components of cardiovascular rehabilitation.

Abstract
Background The spread of coronavirus disease 2019 (COVID-19) has dramatically altered the lifestyles of many people worldwide. Several studies reported that body weight of young adults increased during the COVID-19 pandemic; however, weight loss has been observed in the elderly population. Therefore, trends in body composition due to the COVID-19 pandemic may vary depending on the characteristics of the population. This study aimed to investigate the changes in body mass index (BMI), muscle mass, and fat mass before and during the COVID-19 pandemic among patients undergoing hemodialysis. Methods In this retrospective longitudinal study, we enrolled 115 clinically stable outpatients (mean age: 65.7 ± 11.2 years, 62.6% men) who underwent hemodialysis thrice a week. Baseline data were collected between April 2019 and March 2020, before the declaration of the COVID-19 emergency by the Japanese government. The follow-up measurements were performed between July 2020 and March 2021 during the COVID-19 pandemic. Patient characteristics, laboratory data, and BMI measurements were collected from the medical records. Muscle mass and fat mass were measured using bioelectrical impedance analysis. Results BMI and fat mass among the study participants were significantly higher during the COVID-19 pandemic than before the pandemic (p < 0.01), but no significant change in muscle mass was observed. A restricted cubic spline function showed that the increase in BMI appeared to correlate well with fat mass, but not with muscle mass. Conclusions BMI and fat mass of patients on hemodialysis significantly increased due to preventive measures against the COVID-19 pandemic in Japan. These findings may provide useful information in making nutritional management decisions for patients undergoing hemodialysis during and after the COVID-19 pandemic.

Abstract
INTRODUCTION Peripheral artery disease (PAD) is commonly observed in patients undergoing hemodialysis. PAD impairs the vasculature and leads to pathophysiologic changes in the skeletal muscles, causing physical function impairment and physical inactivity in general. However, it is unclear whether PAD adversely affects physical function and physical activity in patients on hemodialysis. METHODS We performed a cross-sectional study with a retrospective review of the data to determine whether PAD is associated with impaired physical function and physical activity in patients undergoing hemodialysis. The study population comprised 310 patients and 88 healthy subjects. PAD was diagnosed based on an ankle-brachial index of <1.00 in patients on hemodialysis. Measurements of physical function included maximum walking speed, muscle strength in the lower extremities, and balance while standing. FINDINGS Of the 310 patients, 84 (27.1%) had PAD. When patients undergoing hemodialysis were divided into those without PAD and those with PAD, both groups had poorer physical function and physical activity than the healthy control subjects. After adjustments for potential confounders, it was found that patients on hemodialysis with PAD had slower walking speed, poorer standing balance, and less physical activity than those without PAD. However, there was no significant difference in lower extremity muscle strength between the two groups. DISCUSSION PAD diagnosed based on an ankle-brachial index of <1.00 was independently associated with impaired physical function and reduced physical activity in patients undergoing hemodialysis.

SARC-F predicts poor motor function, quality of life, and prognosis in older patients with cardiovascular disease and cognitive impairment. Exp Gerontol 2023; 171:112021. [PMID: 36356692 DOI: 10.1016/j.exger.2022.112021] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 11/01/2022] [Accepted: 11/03/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVES We investigated whether SARC-F scores were associated with motor function, quality of life (QOL) related to physical function, and prognosis in older patients with cardiovascular disease (CVD) and cognitive impairment. METHODS This was a retrospective cross-sectional cohort study. The study population consisted of 408 patients with CVD (≥60 years old) who completed the SARC-F questionnaire and Mini-Cog, a cognitive function test, at discharge. Sarcopenia was defined as a total SARC-F score ≥ 4 points. Patients who were cognitively-preserved (Mini-Cog score ≥ 3 points) were excluded. Patients completed the handgrip strength, leg strength, usual gait speed, 6-minute walking distance, short physical performance battery score, and 36-item Short-Form Health Survey Physical Functioning (SF-36PF) tests before discharge. Associations of SARC-F with physical function, QOL, and prognoses (i.e., composite of all-cause death and emergency CVD rehospitalization and the number of CVD rehospitalizations) were investigated. RESULTS Sarcopenia (SARC-F score ≥ 4 points) was associated with poorer motor function test outcomes and SF-36PF scores (all P < 0.001). The correlations remained significant after adjusting for comorbidities (e.g., anemia, prior heart failure, and renal dysfunction). Sarcopenia was also associated with a poorer prognosis (hazard ratio: 1.574; 95 % confidence interval [CI], 1.011-2.445) and an increased risk of CVD rehospitalization (incidence rate ratio: 1.911; 95 % CI, 1.312-2.782) after adjusting for comorbidities. CONCLUSIONS AND IMPLICATIONS In older patients with CVD and cognitive impairment, the SARC-F questionnaire may be a simple and inexpensive tool for identifying patients with decreased motor function and a poor prognosis.

Abstract
INTRODUCTION We examined the association of proteinuria with the risk for heart failure (HF) and other cardiovascular disease (CVD) events in patients with prior history of breast, colorectal, or stomach cancer using a nationwide population-based database. METHODS We conducted this retrospective observation study using the JMDC Claims Database and analyzed 55,191 patients with prior history of breast, colorectal, or stomach cancer. The median age was 54 (48-60) years, and 20,665 participants (37.4%) were men. Using urine dipstick data at baseline, 3,945 and 1,521 participants were categorized as having trace and positive proteinuria, respectively. Using Cox proportional hazards models, we examined the relationship of proteinuria with the incidence of HF and other CVD events. RESULTS Over a mean follow-up of 2.8 ± 2.2 years, 1,597 HF, 124 myocardial infarction, 1,342 angina pectoris, 719 stroke, and 361 atrial fibrillation events were recorded. Kaplan-Meier curves showed that the cumulative incidence for HF increased with proteinuria category (log-rank p < 0.001). After multivariable adjustment, hazard ratios of trace and positive proteinuria for HF were 1.24 (95% CI, 1.04-1.47) and 1.62 (95% CI, 1.30-2.02), respectively. The presence of proteinuria was also associated with a higher risk for angina pectoris and atrial fibrillation. DISCUSSION Proteinuria was associated with a greater risk of developing HF and other CVD events in patients with prior history of cancer. The optimal management strategy for patients with proteinuria and cancer needs to be established for the prevention of HF in cancer patients.

Abstract
BACKGROUND The clinical benefit of blood pressure (BP) reduction in individuals with diabetes has not been fully elucidated. We sought to identify the clinical impact of BP reduction on incident cardiovascular disease in people having diabetes and hypertension. METHODS We conducted a retrospective cohort study including 754,677 individuals (median age 47 years, 75.8 % men) with stage 1/stage 2 hypertension. Participants were categorized using fasting plasma glucose (FPG) at baseline as normal FPG (FPG < 100 mg/dL) (n = 517,372), prediabetes (FPG:100-125 mg/dL) (n = 197,836), or diabetes mellitus (FPG ≥126 mg/dL) (n = 39,469). The primary outcome was heart failure (HF), and the secondary outcomes included ischemic heart disease (IHD) including myocardial infarction and angina pectoris, and stroke. RESULTS Over a mean follow-up of 1111 ± 909 days, 18,429 HFs, 17,058 IHDs, and 8,795 strokes were recorded. Reduction in BP of< 120/80 mmHg at 1year was associated with a lower risk of developing HF (HR:0.77, 95% CI:0.72-0.82), IHD (HR:0.84, 95% CI:0.79-0.89), and stroke (HR:0.75, 95% CI:0.69-0.82) in individuals with normal FPG, whereas it was not associated with a risk of developing HF (HR:0.98, 95% CI:0.81-1.17) and stroke (HR:0.82, 95% CI:0.62-1.09) in those with DM. Interaction analyses showed that the influence of BP reduction on incident HF was attenuated with people with prediabetes or DM. A multitude of sensitivity analyses confirmed our results. CONCLUSIONS The association of BP reduction with the risk of developing HF was attenuated with deteriorating glucose tolerance. The optimal management strategy for hypertensive people with prediabetes or DM for the prevention of developing cardiovascular disease (particularly HF) is needed to be established.

Simplified discriminant parameters for sarcopenia among patients undergoing haemodialysis. J Cachexia Sarcopenia Muscle 2022; 13:2898-2907. [PMID: 36058558 PMCID: PMC9745501 DOI: 10.1002/jcsm.13078] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Revised: 07/26/2022] [Accepted: 08/14/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Patients with end-stage renal disease (ESRD) are at an increased risk of developing sarcopenia, which can lead to various adverse health outcomes. Although the diagnosis of sarcopenia is essential for clinical management, it is not feasible in routine clinical practice for populations undergoing haemodialysis because it is time-consuming and resources are limited. Serum creatinine levels in patients with ESRD have been gaining attention as a screening parameter for sarcopenia because serum creatinine is a routinely measured byproduct of skeletal muscle metabolism. This study aimed to evaluate the discriminative ability of the creatinine-derived index for sarcopenia in patients undergoing haemodialysis. METHODS We diagnosed sarcopenia according to the Asian Working Group for Sarcopenia (AWGS) 2 criteria in 356 clinically stable outpatients with ESRD enrolled from three dialysis facilities. We adopted the modified creatinine index as a simplified discriminant parameter for sarcopenia in addition to the calf circumference, SARC-F score, and combination of both (i.e. SARC-CalF score), which are recommended by the AWGS. Receiver operating characteristic analysis and logistic regression analysis were conducted to evaluate the discriminative ability of the modified creatinine index for sarcopenia. RESULTS Of the study participants, 142 (39.9%) were diagnosed with sarcopenia. The areas under the curve of the modified creatinine index against sarcopenia in the male and female participants were 0.77 (95% confidence interval [CI]: 0.71 to 0.83) and 0.77 (95% CI: 0.69 to 0.85), respectively. All simplified discriminant parameters were significantly associated with sarcopenia, even after adjusting for patient characteristics and centre. In the comparison of the odds ratios for sarcopenia for 1-standard deviation change in the simplified discriminant parameters, the odds ratio of the modified creatinine index was 1.92 (95% CI: 1.15 to 3.19), which was lower than that of the calf circumference (odds ratio: 6.58, 95% CI: 3.32 to 13.0) and similar to that of the SARC-F (odds ratio: 1.57, 95% CI: 1.14 to 2.16) and SARC-CalF scores (odds ratio: 2.36, 95% CI: 1.60 to 3.47). CONCLUSIONS This study revealed a strong association between the creatinine-derived index and sarcopenia in patients undergoing haemodialysis. The modified creatinine index was equal or superior to those of SARC-F and SARC-CalF score in discriminability for sarcopenia. However, the ability of the calf circumference to discriminate sarcopenia is extremely high, and further study is needed to determine whether it can be used to detect deterioration of muscle mass and function over time.

PURPOSE To identify longitudinal changes in life-space mobility and the factors influencing it among chronic, stable post-stroke patients. MATERIALS AND METHODS This prospective study included Japanese post-stroke patients who received day-care rehabilitation services and could undergo three life-space mobility assessments (at baseline, 12, and 24 months) for over 2 years, using the Life-Space Assessment (LSA) tool. Physical function, cognitive function, and activities of daily living were assessed by self-selected comfortable gait speed, Mini-Mental State Examination (MMSE), and Functional Independence Measure Motor subscale (FIM motor) scores, respectively, in addition to age, sex, time from onset, stroke type, and comorbidities. A multivariable linear mixed-effects model was used to examine the longitudinal changes in LSA scores and associated factors. RESULTS A total of 89 participants were enrolled. At baseline, the median age was 74 years, 33% were women, and median time from onset was 75 months. The LSA scores significantly declined over the two-year period. In the multivariate linear mixed-effects model adjusted for clinical characteristics, comfortable gait speed and age were significantly associated with changes in the LSA score, independent of FIM motor scores and MMSE scores. CONCLUSIONS Life-space mobility may persistently decline, and gait function may be a determinant influencing these changes in community-dwelling chronic post-stroke patients.Implications for RehabilitationLimited life-space mobility leads to less frequent participation in social activities and an increased risk of adverse health outcomes such as hospitalization.Changes in life-space mobility should be considered in the rehabilitation care plan for chronic post-stroke patients.Life-space mobility may decline persistently in stable post-stroke patients, even if they have periodically received day-care rehabilitation services.Since gait speed is a predominant factor affecting life-space mobility, regular assessment of gait function and appropriate strategies are needed to prevent deterioration of gait speed in chronic post-stroke patients.

Relationship between the spread of COVID-19, social frailty, and depressive symptoms in patients with heart failure. Heart Vessels 2022; 38:992-996. [PMID: 36449044 PMCID: PMC9709749 DOI: 10.1007/s00380-022-02203-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 11/10/2022] [Indexed: 12/05/2022]
Abstract
In community-dwelling older people, coronavirus disease 2019 (COVID-19) has been reported to be associated with the development of frailty and depressive symptoms. We aimed to investigate whether the spread of COVID-19 is associated with the development of frailty in patients with heart failure (HF). The presence of the multi-domain of frailty in 257 patients with HF was assessed at hospital discharge. The spread of COVID-19 was significantly associated with the development of social frailty and depressive symptoms. Evaluation of these symptoms during hospitalization would support disease management and understanding of their social and psychological conditions.

Correlation between respiratory muscle weakness and frailty status as risk markers for poor outcomes in patients with cardiovascular disease. Eur J Cardiovasc Nurs 2022; 21:782-790. [PMID: 35259240 DOI: 10.1093/eurjcn/zvac014] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 12/18/2021] [Accepted: 02/25/2022] [Indexed: 12/29/2022]
Abstract
AIMS Although the developmental mechanism of respiratory muscle weakness (RMW) and frailty are partly similar in patients with cardiovascular disease (CVD), their relationship remains unclear. This study aimed to investigate the correlation between RMW and frailty and its impact on clinical outcomes in patients with CVD. METHODS AND RESULTS In this retrospective observational study, consecutive 1217 patients who were hospitalized for CVD treatment were enrolled. We assessed frailty status by using the Fried criteria and respiratory muscle strength by measuring the maximal inspiratory pressure (PImax) at hospital discharge, with RMW defined as PImax <70% of the predicted value. The endpoint was a composite of all-cause death and/or readmission for heart failure. We examined the prevalence of RMW and frailty and their correlation. The relationships of RMW with the endpoint for each presence or absence of frailty were also investigated. Respiratory muscle weakness and frailty were observed in 456 (37.5%) and 295 (24.2%) patients, respectively, and 149 (12.2%) patients had both statuses. Frailty was detected as a significant indicator of RMW [odds ratio: 1.84, 95% confidence interval (CI): 1.39-2.44]. Composite events occurred in 282 patients (23.2%). Respiratory muscle weakness was independently associated with an increased incidence of events in patients with both non-frailty [hazard ratio (HR): 1.40, 95% CI: 1.04-1.88] and frailty (HR: 1.68, 95% CI: 1.07-2.63). CONCLUSIONS This is the first to demonstrate a correlation between RMW and frailty in patients with CVD, with 12.2% of patients showing overlap. RMW was significantly associated with an increased risk of poor outcomes in patients with CVD and frailty.

Abstract
BACKGROUND The optimal value of BMI for the development of hypertension and the influence of BMI on the development of stage 1 or stage 2 hypertension remain unclear. OBJECTIVES We sought to identify the BMI threshold for the prevention of hypertension and how changes in BMI would influence the risk of developing hypertension. METHODS We analyzed 1,262,356 participants (median age: 43 y; 50.9% men) with normal blood pressure [BP; systolic BP (SBP) <120 mmHg and diastolic BP (DBP) <80 mmHg] or elevated BP (SBP: 120-129 mmHg and DBP <80 mmHg). The primary outcome was stage 1 (SBP 130-139 mmHg or DBP 80-89 mmHg) or stage 2 hypertension (SBP ≥140 mmHg or DBP ≥90 mmHg). We analyzed the relation between baseline BMI, change in BMI, and the risk of developing hypertension using generalized additive models with a smoothing spline. RESULTS During the median follow-up of 851 d, 341,212 cases of stage 1 hypertension and 70,968 cases of stage 2 hypertension were detected. The risk of developing stage 1 or stage 2 hypertension increased steeply after BMI (kg/m2) exceeded 20. The annual change in BMI was positively correlated with the risk of developing stage 1 or 2 hypertension. Contour mapping using generalized additive models demonstrated an additive increase in the risk of developing hypertension with higher baseline BMI and increases in BMI over 1 y. Body-weight gain increases the risk of developing hypertension even in underweight or normal-weight individuals based on the WHO classification. CONCLUSIONS In Japanese adults with normal or elevated BP, the risk of developing hypertension increased with BMI when baseline BMI was >20. Body-weight gain additively interacted with baseline BMI during hypertension development. Our results underscore the importance of maintaining body weight in preventing the development of hypertension.

Association between SGLT2 Inhibitors and Cardiac Rehabilitation Outcomes in Patients with Cardiovascular Disease and Type 2 Diabetes Mellitus. J Clin Med 2022; 11:jcm11195956. [PMID: 36233823 PMCID: PMC9571431 DOI: 10.3390/jcm11195956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 09/21/2022] [Accepted: 10/05/2022] [Indexed: 11/07/2022] Open
Abstract
The use of sodium-glucose cotransporter 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus (T2DM) has been associated with decreased skeletal muscle mass but remains unclear in patients with cardiovascular disease (CVD) undergoing comprehensive outpatient cardiac rehabilitation (CR). Therefore, this study investigates the effect of SGLT2 inhibitors on the outcomes of patients with CVD and T2DM undergoing comprehensive outpatient CR. The study included 402 patients with CVD and T2DM who participated in comprehensive outpatient CR. Physical functions (grip strength, maximal quadriceps isometric strength, usual gait speed, and 6-minute walking distance) were measured at discharge as baseline and 5 months thereafter, and the association between physical functions and SGLT2 inhibitor use was reviewed. Physical functions improved regardless of SGLT2 inhibitor use. Multiple regression analysis showed that SGLT2 inhibitor use was not associated with improvement or decline in physical functions (p ≥ 0.05). The use of SGLT2 inhibitors in patients with CVD and T2DM undergoing outpatient CR did not impair improvement in physical functions.

Abstract
Abstract
Background
Early rehabilitation in the intensive care unit (ICU), including early mobility therapy, is known to improve the clinical outcomes in patients with critically ill. However, the effectiveness of acute-phase cardiovascular rehabilitation (CR) during ICU treatment have not been thoroughly evaluated in patients with cardiovascular disease (CVD).
Purpose
We aimed to investigate the trends and outcomes of acute-phase CR in the ICU for patients with CVD, including in-hospital and long-term clinical outcomes.
Methods
We reviewed 1948 consecutive patients with CVD admitted to tertiary academic ICU at a university hospital. Patients were arbitrarily assessed by an ICU team consisting of medical and surgical doctors, nurses and physiotherapists within 24 hours after admission to ICU to discover whether their rehabilitation could be initiated according to the specific clinical trial and statement. As clinical characteristics, disease aetiology, comorbid conditions, and ICU treatment were obtained from an electronic database. We evaluated the probability of return to walking independence and return to home as in-hospital clinical outcomes. All patients were followed for five years and investigated all-cause and cardiovascular events after hospital discharge as long-term clinical outcomes. The associations between the implementation of CR during ICU treatment (ICU-CR) and clinical outcomes were evaluated using propensity score-matched analysis with adjustment for clinical characteristics in all matched patients and various subgroups, including aged >65 years, surgical patients, emergency, and length of ICU stay ≥48 hours.
Results
Out of studied patients, 1092 patients received ICU-CR, the number of which positively correlated with year-trend (r=0.986, P<0.001). After propensity score matching with adjustment for clinical characteristics including calendar years, 758 patients were included for analysis (pairs of n=379 ICU-CR and non-ICU-CR). The ICU-CR was significantly associated with a higher probability of return to walking independence (incident rate ratio [IRR], 2.04; 95% confidence interval [CI], 1.77–2.36) and return to home (IRR, 1.22 95% CI, 1.05–1.41). These associations were consistently observed in various subgroups regarding CVD conditions (Figure 1). During the median follow-up periods of 2.6 years, all-cause clinical events and cardiovascular events occurred in 289 patients (38.1%) and 153 patients (20.2%), respectively. The ICU-CR showed significantly lower rates of five-year all-cause and cardiovascular events than non-ICU-CR (hazard ratio [95% CI] for all-cause events and cardiovascular events, 0.71 [0.56–0.89] and 0.69 [0.50–0.95], respectively, Figure 2).
Conclusions
The implementation of acute-phase CR in the ICU increased with year-trend, considered beneficial to improve in-hospital and long-term clinical outcomes in patients with CVD and various subgroups of relatively severe disease conditions.

Association of Cardiovascular Health Metrics With Risk of Transition to Hypertension in Non-Hypertensive Young Adults. Am J Hypertens 2022; 35:858-866. [PMID: 35639507 DOI: 10.1093/ajh/hpac057] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 05/02/2022] [Accepted: 05/04/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND The risk of developing hypertension in young adults and its relationship to modifiable lifestyle factors are unclear. We aimed to examine the association of cardiovascular health (CVH) metrics with the risk of hypertension. METHODS We analyzed 66,876 participants aged 20-39 years, with available blood pressure (BP) data for 5 consecutive years, who had normal or elevated BP at the initial health check-up, enrolled in the JMDC Claims Database. Ideal CVH metrics included nonsmoking, body mass index <25 kg/m2, physical activity at goal, optimal dietary habits, untreated fasting glucose <100 mg/dL, and untreated total cholesterol <200 mg/dL. The primary endpoint was defined as stage 1 or stage 2 hypertension. We defined normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension according to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) BP guideline. RESULTS The median age was 35 years, and 62% were men. Number of non-ideal CVH metrics was associated with an increasing risk for the development of stage 1 and stage 2 hypertension. Non-ideal body mass index was most strongly associated with a risk for hypertension. This association was more pronounced in women. An annual increase in the number of non-ideal CVH metrics was associated with an elevated risk for the hypertension development. CONCLUSIONS CVH metrics can stratify the risk for hypertension in non-hypertensive adults aged 20-39 years. These findings have important public health implications for the screening and prevention of hypertension. Improving CVH metrics may prevent the risk of developing hypertension in young adults.

Perme ICU Mobility Score as a comprehensive assessment tool of acute-phase rehabilitation is correlated with clinical outcomes in patients after cardiovascular surgery. Eur Heart J 2022.

Abstract
Abstract
Background
Early mobility therapy in the intensive care unit (ICU) is widely employed to improve the physical function and prognosis of patients with critically ill. On the other hand, patients who undergo cardiovascular surgery frequently suffer from disabilities after ICU care due to their cardiopulmonary conditions and treatments. However, few studies have reported the procedures and assessments of acute-phase rehabilitation in these patients. Recently, the Perme ICU Mobility Score (Perme Score) was developed as a reliable tool to assess comprehensive mobility status of patients in the ICU. We hypothesised that the Perme Score is a useful tool for assessing the mobility levels in the ICU and predicting clinical outcomes in patients undergoing acute-phase rehabilitation after cardiovascular surgery.
Purpose
To investigate the associations between the Perme Score within the second days after cardiovascular surgery and the patients' clinical outcomes, including physical function and the incidence of clinical events.
Methods
We studied 224 consecutive patients (34.4% female; aged 65±13 years) who were admitted to the ICU of a tertiary academic hospital after cardiac and/or major vascular surgery. Clinical characteristics including patient profiles, comorbidities, surgical details and APACHE II and SOFA scores were evaluated on ICU admission. The Perme Score contains categories on mental status, potential mobility barriers, muscle strength and mobility level, with higher scores indicating greater activity levels in the ICU. We assessed the Perme Score within the second days after the surgery. As a physical function at hospital discharge, we measured the six-minute walk distance (6MWD). The primary endpoint was a composite outcome of the number of all-cause mortality and/or all-cause unplanned readmission. We analysed the associations of the Perme Score with the 6MWD and the incidence of clinical events using multiple regression analysis and multivariate Poisson regression analysis, respectively.
Results
After adjusting for clinical confounding factors, a higher Perme Score was an independent factor of a higher 6MWD (Table 1). During the median follow-up period of 1.3 years, 51 cases of all-cause mortality/readmission occurred in 37 (16.5%) patients, with an incidence rate of 18.6/100 person-years. In the multivariate Poisson regression analysis, even after adjusting for the severity score in the ICU, a higher Perme Score was significantly and independently associated with lower rates of all-cause clinical events (adjusted incident rate ratio: 0.96, 95% confidence interval: 0.93–0.99, P=0.008, Figure 1).
Conclusions
The Perme Score within the second days after cardiovascular surgery is correlated with physical function at hospital discharge and the incidence of clinical events after discharge. Thus, a comprehensive assessment of acute-phase rehabilitation after cardiovascular surgery may be useful in predicting clinical outcomes.

Abstract
Abstract
Introduction
The emerging interdisciplinary field of cardio-oncology is of interest to clinicians because a history of cancer or cancer treatment is considered a severe risk factor for cardiovascular disease (CVD). Both cancer and CVD can reduce skeletal muscle mass; together, they can lead to a poorer prognosis. However, it is unclear whether a patient's cancer history can lower physical function and lead to a poor prognosis with the coexistence of cancer history and physical dysfunction in patients with CVD. This study aimed to identify the relationship between cancer history and physical function, as well as the prognostic value of their combination, in patients with CVD.
Methods
We reviewed 3,640 patients with CVD (mean age, 67.9±13.5 years) who underwent physical-function tests (gait speed and 6-min walking distance [6MWD]). We performed multivariate linear regression analysis to assess potential associations between cancer history and physical-function tests in patients with CVD. Additionally, we used the Kaplan–Meier curve and Cox regression analyses to assess survival and prognostic significance for patients divided into four groups according to the presence or absence of cancer history and high or low physical function.
Results
In multivariate linear regression analysis, cancer history was independently associated with lower gait speed and 6MWD (gait speed, P=0.048 and 6MWD, P=0.040). A total of 581 deaths occurred over a median follow-up period of 3.08 years (interquartile range: 1.36–5.27). For all-cause mortality, patients with a history of cancer and reduced physical function were found to have a significantly higher mortality risk even after adjusting for several covariates (gait speed, HR: 1.66, P=0.003 and 6MWD, HR: 1.71, P=0.003).
Conclusion
Cancer history was correlated with physical dysfunction in patients with CVD. Moreover, the coexistence of cancer history and physical dysfunction resulted in poorer prognosis in patients with CVD.

Abstract
Abstract
Introduction
While the major outcome of cardiac rehabilitation for heart failure (HF) is the improvement of exercise tolerance, prognosis, and quality of life, instrumental activities of daily living (IADL) has also been focused on as one of the its outcomes. IADL has been reported to be associated with all-cause mortality and quality of life in community-dwelling people and in patients with stable heart disease, but no report has examined the relationship between IADL after cardiac rehabilitation for HF and prognosis. In addition, it is assumed that sex differences may affect the frequency of performing each component of IADL, but there are no reports examining the association with prognosis by sex.
Purpose
The present study aimed to investigate the sex differences in frequency of IADL and its impact on outcomes.
Methods
We retrospectively studied 490 consecutive patients who were admitted due to acute decompensated HF and participated in outpatient cardiac rehabilitation after discharge. The study was performed in accordance with the tenets of the Declaration of Helsinki, and the protocol was approved by the Ethics Committee of our institution. IADL frequency was assessed using the questionnaire-based Frenchay Activities Index (FAI). The primary endpoint was all-cause death and secondary endpoint was combined events (all-cause death and/or readmission due to HF). We performed the Kaplan–Meier and log-rank tests and multivariable Cox regression analysis to evaluate the prognostic predictive capability of the FAI.
Results
The study population had a median age of 69 (interquartile range [IQR]: 58–76) years, and 33.9% of patients were females. The median FAI score was 24 (IQR: 16–29) points. According to the Youden index based on the area under the curve calculated by the receiver operating characteristics curve, the cut-off values of FAI for all-cause death in all-over, females, and males were 23, 22, and 23 points, respectively. Over a median follow-up period of 4.8 years (IQR: 2.3–6.6 years), all-cause death and combined events were occurred in 95 (19.4%) and 213 (43.5%), respectively. After adjustment for several pre-existing prognostic factors, IADL assessed by the FAI was independently associated with all-cause mortality (hazard ratio [HR]: 0.961, 95% confidence interval [CI]:0.937–0.986) and combined events (HR: 0.968, 95% CI: 0.952–0.985), respectively. In addition, there was no interaction between sex in prognostic capability (P=0.664).
Conclusion
Lower IADL frequency assessed by FAI at the end of outpatient cardiac rehabilitation was shown to be associated with poorer prognosis in patients with HF, regardless of sex. The IADL level is generally higher in females than in males but seems to be a useful marker for risk stratification at the end of cardiac rehabilitation in both females and males.

Abstract
Abstract
Introduction
Exercise intolerance in patients with heart failure (HF) is a strong indicator of a poor prognosis. As the respiratory impairment in HF patients, the small airway is reportedly more susceptible than central airways, which results in increased airway resistance and may cause poor outcomes. However, the impact of small-airway disease (SAD) on exercise intolerance and prognosis in patients with HF is still unclear.
Purpose
We investigated the associations between SAD and exercise intolerance in patients with HF, and the clinical significance of SAD for long-term clinical events with a reduced or preserved ejection fraction.
Methods
We reviewed 1015 patients with HF (mean age, 66.9±14.6 years; male, 64.5%) admitted for medical treatment. Patients with a prior history of chronic respiratory disease or an obstructive lung pattern – defined as the forced expiratory volume (%) in 1 s relative to <70% forced vital capacity using spirometry – were excluded. Characteristics including HF aetiology, comorbidities conditions, medications, blood parameters, and echocardiographic variables were obtained from clinical records. All patients underwent spirometry at hospital discharge, and SAD was defined as the maximum mid-expiratory flow (%) relative to a <60% predicted value. At hospital discharge, we measured 6-min walk distance (6MWD), and <300 m was considered as exercise intolerance. The primary endpoint was a composite clinical event of all-cause death and/or unplanned readmission for HF. Multivariate logistic regression analysis was used to assess the association between SAD and exercise intolerance. The multivariate Cox proportional hazard model was used to clarify whether SAD was an independent predictor for the incidence of clinical events. We also performed subgroup analyses in each multivariate analysis based on a left ventricular ejection fraction (LVEF) of 40%.
Result
SAD was observed in 479 (47.2%) patients. LVEF subgroups included 458 (45.1%) and 518 (51.0%) patients with LVEF <40% and ≥40%, respectively. After adjusting for clinical characteristics, SAD was independently associated with 6MWD <300 m (Figure 1). Moreover, this association was consistently observed in the LVEF <40% and ≥40% (Figure 1). During the median follow-up period of 1.5 years, all-cause death/readmission occurred in 431 patients (42.5%), and the incidence rate was 17.5/100 person-years. In the multivariate Cox proportional hazard model, SAD was independently associated with lower event-free survival rates in all patients and the LVEF <40% subgroup, but not LVEF ≥40% subgroup (Figure 2A, B, and C, respectively).
Conclusion
This study is the first to reveal that SAD is associated with exercise intolerance in patients with HF regardless of LVEF. Moreover, SAD may have a predictive significance for long-term outcomes in patients with HF and subgroups with reduced, but not preserved ejection fraction.

Associations between dynapenia, cardiovascular hospitalizations, and all-cause mortality among patients on haemodialysis. J Cachexia Sarcopenia Muscle 2022; 13:2417-2425. [PMID: 35916353 PMCID: PMC9530547 DOI: 10.1002/jcsm.13039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 04/25/2022] [Accepted: 06/25/2022] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Low muscle strength is associated with adverse clinical outcomes in patients undergoing haemodialysis (HD). No studies have reported the association between dynapenia, defined by both low handgrip strength (HGS) and quadriceps isometric strength (QIS), and long-term clinical outcomes in patients on HD. We examined the associations between dynapenia, cardiovascular (CV) hospitalizations, and all-cause mortality in the HD population. METHODS This retrospective study used data from outpatients undergoing HD at two dialysis facilities between October 2002 and March 2020. We defined low muscle strength as an HGS of <28 kg for men and <18 kg for women and a QIS of <40% dry weight. Furthermore, we categorized dynapenia into three groups: robust ('high HGS and high QIS'), either low HGS or low QIS ('low HGS only' or 'low QIS only'), and dynapenia ('low HGS and low QIS'). The outcomes were all-cause mortality and a composite of CV hospitalizations and mortality. Cox proportional hazards and negative binomial models were used to examine these associations. RESULTS A total of 616 patients (mean age, 65.4 ± 12.2 years; men, 61%) were included in the analyses. During the follow-up (median, 3.0 years), a total of 163 deaths and 288 CV hospitalizations occurred. Patients with the either low HGS or low QIS [hazard ratio (HR), 1.75; 95% confidence intervals (CIs), 1.46-2.10] and dynapenia (HR, 2.80; 95% CIs, 2.49-3.14) had a higher risk of mortality than those in the robust group. When compared with the robust group, the either low HGS or low QIS [incidence rate ratio (IRR): 1.41, 95% CI: 1.00-1.99] and dynapenia (IRR: 2.04, 95% CI: 1.44-2.89) groups were associated with a significantly higher incident risk of CV hospitalizations. CONCLUSIONS Dynapenia (muscle weakness in both upper and lower extremities) was associated with increased risks of all-cause mortality and CV hospitalizations among patients on HD. Screening for dynapenia using both HGS and QIS may be useful for prognostic stratification in the HD population.

Abstract
Abstract
Background
Accurately identifying the factors contributing to decline in activities of daily living (ADL) is important for preventing such decline in patients undergoing hemodialysis (HD). We studied the prevalence and number of overlapping psychiatric symptoms (depressive symptoms, apathy, and sleep disturbance) in patients undergoing HD and examined the relationship between psychiatric symptoms and ADL.
Methods
The study utilized a cross-sectional research design. The sample included 203 outpatients (median age: 69 years) undergoing stable HD treatment three times a week. Patient characteristics, including age, sex, body composition, dialysis vintage, primary kidney disease, comorbidity, and nutritional status, were collected from patients’ medical records. Functional status was assessed based on the self-reported questionnaire that combined five basic and eight instrumental ADL items. Usual walking speed was used as an index of physical function. Additionally, the short version of the Center for Epidemiologic Studies Depression Scale was used to assess depressive symptoms. Further, apathy and sleep disturbance were assessed using the Motivation Score and the Athens Insomnia Scale, respectively.
Results
Overall, 59 (29.1%) patients demonstrated depressive symptoms, 100 (49.3%) reported apathy, 83 (40.9%) had sleep disturbance, 31 (15.3%) had three overlapping psychiatric symptoms, 43 (21.2%) had two overlapping psychiatric symptoms, 63 (31.0%) had only one symptom, and 66 (32.5%) had no psychiatric symptoms. Multiple logistic regression analysis showed that having two or three overlapping psychiatric symptoms was independently and significantly associated with ADL (functional status of 13 points for the ADL maintenance group, and of < 13 points for the ADL decline group, respectively), even after adjusting for patient characteristics and walking speed (odds ratio: 2.74, 95% confidence interval: 1.12–6.69, reference; no psychiatric symptoms).
Conclusion
The present study clarified that the overlapping symptoms, including depressive symptoms, apathy, and sleep disturbance, were independently associated with ADL decline in patients undergoing HD. It is useful to examine not only depressive symptoms but also other symptoms such as apathy and sleep disturbance to elucidate factors associated with deteriorated ADL in chronic patients. Our findings provide a strong basis for targeted interventions to prevent functional dependence in the HD population.

Detailed Changes in Oxygenation following Awake Prone Positioning for Non-Intubated Patients with COVID-19 and Hypoxemic Respiratory Failure—A Historical Cohort Study. Healthcare (Basel) 2022; 10:healthcare10061006. [PMID: 35742057 PMCID: PMC9222739 DOI: 10.3390/healthcare10061006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 05/24/2022] [Accepted: 05/27/2022] [Indexed: 12/04/2022] Open
Abstract
Few studies have reported on the effectiveness of awake prone therapy in the clinical course of coronavirus disease (COVID-19) patients. This study aimed to investigate the effects of awake prone therapy during spontaneous breathing on the improvement of oxygenation over 3 weeks for COVID-19 acute respiratory failure. Data of consecutive COVID-19 patients with lung disorder with a fraction of inspired oxygen (FIO2) ≥ 0.4 and without tracheal intubation were analyzed. We examined changes in SpO2/FIO2, ROX index ((SpO2/FIO2)/respiratory rate) and the seven-category ordinal scale after the initiation of FIO2 ≥ 0.4 and compared these changes between patients who did and did not receive prone therapy. Of 58 patients, 27 received awake prone therapy, while 31 did not. Trend relationships between time course and change in SpO2/FIO2 and ROX index were observed in both groups, although a significant interaction in the relationship was noted between prone therapy and change in SpO2/FIO2 and ROX index. The seven-category ordinal scale also revealed a trend relationship with time course in the prone therapy group. The awake prone therapy was significantly associated with a lower rate of tracheal intubation. In patients with COVID-19 pneumonia treated with FIO2 ≥ 0.4, awake prone therapy may improve oxygenation within two weeks.

Comparison of cardiovascular outcomes between SGLT2 inhibitors in diabetes mellitus. Cardiovasc Diabetol 2022; 21:67. [PMID: 35585590 PMCID: PMC9115977 DOI: 10.1186/s12933-022-01508-6] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 04/22/2022] [Indexed: 11/17/2022] Open
Abstract
Background There have been scarce data comparing cardiovascular outcomes between individual sodium-glucose cotransporter-2 (SGLT2) inhibitors. We aimed to compare the subsequent cardiovascular risk between individual SGLT2 inhibitors. Methods We analyzed 25,315 patients with diabetes mellitus (DM) newly taking SGLT2 inhibitors (empagliflozin: 5302, dapagliflozin: 4681, canagliflozin: 4411, other SGLT2 inhibitors: 10,921). We compared the risks of developing heart failure (HF), myocardial infarction (MI), angina pectoris (AP), stroke, and atrial fibrillation (AF) between individual SGLT2 inhibitors. Results Median age was 52 years, and 82.5% were men. The median fasting plasma glucose and HbA1c levels were 149 (Q1-Q3:127–182) mg/dL and 7.5 (Q1-Q3:6.9–8.6) %. During a mean follow-up of 814 ± 591 days, 855 HF, 143 MI, 815 AP, 340 stroke, and 139 AF events were recorded. Compared with empagliflozin, the risk of developing HF, MI, AP, stroke, and AF was not significantly different in dapagliflozin, canagliflozin, and other SGLT inhibitors. For developing HF, compared with empagliflozin, hazard ratios of dapagliflozin, canagliflozin, and other SGLT2 inhibitors were 1.02 (95% confidence interval [CI] 0.81–1.27), 1.08 (95% CI 0.87–1.35), and 0.88 (95% CI 0.73–1.07), respectively. Wald tests showed that there was no significant difference in the risk of developing HF, MI, AP, stroke, and AF among individual SGLT2 inhibitors. We confirmed the robustness of these results through a multitude of sensitivity analyses. Conclusion The risks for subsequent development of HF, MI, AP, stroke, and AF were comparable between individual SGLT2 inhibitors. This is the first study comparing the wide-range cardiovascular outcomes of patients with DM treated with individual SGLT2 inhibitors using large-scale real-world data.

Background
Owing to the spread of coronavirus disease 2019 (COVID-19), people have refrained from going out unnecessarily and have been maintaining social distance. These new lifestyle approaches have affected people physically, psychologically, and socially. Patients with heart failure (HF) are more likely to have social frailty, physical frailty, cognitive impairment, and depressive symptoms, and an overlap of these conditions leads to adverse events. Therefore, multi-domain assessment and understanding of the condition of patients with HF are important for disease management. The spread of COVID-19 is a predicted risk factor for these events, but its impact in patients with HF has not been investigated.
Purpose
We investigated whether the spread of COVID-19 is associated with the development of the multi-domain of frailty in patients with HF.
Methods
Patients who were independent in their daily activities before admission were included in the study. The presence of social frailty (Makizako’s five items), physical frailty (Fried phenotype model), cognitive impairment (Mini-Cog), and depressive symptoms (the Patient Health Questionnaire-2) in patients with HF were assessed at hospital discharge. Logistic regression analyses were used to examine the impact of the spread of COVID-19 on the development of the multi-domain of frailty in patients with HF.
Results
We included 482 patients in this study. Median patient age was 74 years, and 64.5% were male. In multivariate logistic regression analyses, the spread of COVID-19 was significantly associated with the development of social frailty (odds ratio [OR]: 1.15, 95% confidence interval [CI]: 1.02–1.30) and depressive symptoms (OR: 1.14, 95% CI: 1.02–1.27) but not with the development of physical frailty (OR: 1.24, 95% CI: 0.51–3.02) and cognitive impairment (OR: 1.72, 95% CI: 0.80–3.73).
Conclusion
The spread of COVID-19 was associated with the development of social frailty and depressive symptoms in patients with HF. Evaluation of social frailty and depressive symptoms during hospitalization would support disease management and understand their social and psychological conditions specific to the spread of COVID-19.

Background
It is widely known that patients with acute coronary syndrome (ACS) are at increased risk of nonalcoholic fatty liver disease (NAFLD), which is linked to sarcopenia and physical dysfunction. However, the relationship between metabolic dysfunction-associated fatty liver disease (MAFLD) and physical dysfunction remains unclear.
Purpose
The purpose of this study was to investigate the prevalence of MAFLD in patients with ACS to assess the relationship between MAFLD and muscle strength, walking speed, and 6-minute walking distance (6 MWD).
Methods
We reviewed patients with ACS who were assessed for hepatic steatosis using the fatty liver index, and the results were further assessed to determine the presence of MAFLD. Multiple regression analysis was used to examine the association between MAFLD and physical function.
Results
Among 479 enrolled hospitalized patients, MAFLD was identified in 234 (48.9%) patients. We conducted a multiple regression analysis in which MAFLD was independently associated with lower leg strength, gait speed, and 6 MWD (leg strength, P = 0.023; gait speed, P = 0.002 and 6 MWD, P = 0.017). Furthermore, having more metabolic impairment was still associated with lower physical function decline (leg strength, P for trend = 0.002; gait speed, P for trend = 0.019 and 6 MWD, P for trend = 0.003).
Conclusions
MAFLD is common in hospitalized patients with ACS, and most patients with MAFLD have many overlapping metabolic abnormalities. MAFLD is associated with impaired physical function, and the greater the number of overlapping metabolic abnormalities, the worse the motor function.

Background
Sarcopenia is a chronic condition that is characterized by the loss of skeletal muscle mass with declining muscle strength and/or performance that occurs gradually with aging. It has been reported that sarcopenia is highly prevalent in patients with heart failure (HF) and is a poor prognostic factor. Therefore, it is important to accurately assess skeletal muscle mass in patients with HF. However, there are no reports that have simultaneously examined different skeletal muscle mass metrics as factors in the prognosis of HF patients.
Purpose
The purpose of this study is to examine if the different skeletal muscle mass metrics are associated with the prognosis of HF patients.
Methods
We examined a total of 869 patients with HF, aged ≥20 years (73 [63, 80] years; 537 males), who were admitted to our hospital and participated in an inpatient cardiac rehabilitation program. We used skeletal muscle mass index (SMI) as measured by bioelectrical impedance analysis (BIA), mid-upper arm circumference (MUAC), arm muscle circumference (AMC), and calf circumference (CC) as metrics of skeletal muscle mass. The primary outcome was all-cause deaths, and secondary outcome was HF readmission. To investigate the association between each skeletal muscle mass metric and prognosis, patients were divided into three groups according to the tertiles of SMI, MUAC, AMC, and CC. In addition, cumulative event rates of survival curves, Gray test, and Fine & Gray test were performed to evaluate the prognostic predictive capability.
Results
Over a median follow-up period of 0.9 years (interquartile 0.4–1.9) years, a total of 80 deaths and 195 HF readmissions occurred in the patients. Cumulative event rates of survival curves and Gray test showed that there was a significant decrease in all-cause mortality and HF readmission in the high MUAC group and high AMC group compared to their respective low groups (P < 0.05). Fine & Gray test after multivariate adjustment showed significantly better prognosis in the high MUAC group and high AMC group compared to their respective low groups (All-cause mortality: high MUAC group, subdistribution hazard ratio [sHR] = 0.42, 95% confidence interval [CI] = 0.20-0.88, P < 0.05; high AMC group, sHR = 0.34, 95%CI = 0.16-0.72 P < 0.05, HF readmission: high MUAC group, sHR = 0.69, 95%CI = 0.47-1.00, P < 0.05; high AMC group, sHR = 0.63, 95%CI = 0.43-0.93, P < 0.05).
Conclusion
Patients with HF who maintained high MUAC and high AMC had a good prognosis. CC and SMI were not associated with the prognosis of HF patients. This suggests the importance of evaluating MUAC and AMC in HF patients.

Abstract
Abstract
BACKGROUND AND AIMS
Low muscle strength is associated with adverse clinical outcomes in patients on hemodialysis (HD). However, the association between dynapenia, characterized by both low handgrip strength (HGS) and leg strength (LS) and long-term clinical outcomes in patients on HD has not yet been reported. Therefore, this study investigated whether dynapenia was associated with higher cardiovascular (CV) hospitalization risk and all-cause mortality in patients on HD.
METHOD
This retrospective study used the data of outpatients on HD from two dialysis facilities between October 2002 and March 2020. This study was approved by the Institutional Review Board/Ethics Committee of Kitasato University of Allied Health Sciences and was conducted in accordance with the principles of the Declaration of Helsinki. All participants provided written informed consent before inclusion in the study. Low muscle strength was defined as an HGS of < 28 kg for men and < 18 kg for women and an LS of < 40% dry weight. Furthermore, dynapenia was categorized into three groups: robust (‘high HGS and high LS’), either low HGS or low LS (‘low HGS only’ or ‘low LS only’) and dynapenia (‘low HGS and low LS’). The outcomes were all-cause mortality and a composite of CV hospitalizations and mortality. These associations were examined using Cox proportional hazards and negative binomial models.
RESULTS
Data from 616 patients (mean age, 65.4 ± 12.2 years; men, 61%) were analyzed. During the follow-up (median, 3.0 years), 163 deaths and 288 CV hospitalizations occurred. Figure 1 shows the results of the Kaplan–Meier survival analyses of the robust, either low HGS or low LS, and dynapenia groups. The log-rank test showed significantly worse survival in the either low HGS or low LS and dynapenia groups than in the robust group (P < 0.001). After adjusting for age, sex, body mass index, HD vintage, comorbidity index, serum albumin, serum hemoglobin, serum creatinine and C-reactive protein levels, patients with either low HGS or low LS [hazard ratio (HR), 1.81; 95% confidence intervals (95% CIs), 1.51–2.17] and dynapenia (HR 2.77, 95% CI 2.48–3.08) were found to have a higher mortality risk than those in the robust group. Similarly, compared with the robust group, either the low HGS or low LS [incidence rate ratio (IRR) 1.45, 95% CI 1.04–2.03] and dynapenia (IRR 2.06, 95% CI 1.48–2.89) groups had higher multiple CV hospitalization and all-cause mortality risks.
CONCLUSION
Dynapenia, characterized by both low HGS and LS, was significantly associated with increased CV hospitalization and mortality risk in patients on HD. Clinical assessments of muscle strength and screening patients with low muscle strength are crucial for disease management in this population. Measuring the muscle strength of the entire extremity, and not only the upper or lower extremities, may be necessary for accurate prognostic stratification.

Optimal cutoff values for physical function tests in elderly patients with heart failure. Sci Rep 2022; 12:6920. [PMID: 35484373 PMCID: PMC9051131 DOI: 10.1038/s41598-022-10622-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Accepted: 04/11/2022] [Indexed: 11/09/2022] Open
Abstract
Six-minute walk distance (6MWD) of 300 and 400 m are important targets of functional capacity. The present study was performed to determine cutoff values of physical function associated with 6MWD < 300 m and < 400 m in elderly patients with heart failure (HF). 6MWD, handgrip strength, quadriceps isometric strength (QIS), one-leg standing time (OLST), and 5-times sit-to-stand (5STS) before hospital discharge were evaluated in 1001 patients > 65 years (median age, 75: interquartile range, 71-80, 607 men) with HF. 6MWD < 300 and < 400 m were seen in 323 patients (32.3%) and 658 patients (65.7%), respectively. Handgrip strength, QIS, OLST, and 5STS were associated with 6MWD < 300 and < 400 m, respectively (P < 0.001). The cutoff values of handgrip strength, QIS, OLST, and 5STS were 18.9 kg, 35.0% body mass (BM), 9.1 s, and 9.5 s for 6MWD < 300 m, and 21.9 kg, 40.0% BM, 12.0 s, and 8.8 s for < 400 m, respectively. The cutoff values of physical function could be used to set cardiac rehabilitation goals and limiting determinants of reduced functional capacity in a clinical setting in elderly patients with HF.

Abstract
BACKGROUND Low skeletal muscle area or density, such as myosteatosis, identified on computed tomography (CT) is associated with poor prognosis in patients with cardiovascular diseases. However, there is a lack of evidence regarding the clinical process of skeletal muscle decline as a short-term change during acute care settings. This study focused on the use of routine CT imaging for aortic disease management and investigated the changes in skeletal muscle before and after acute care. METHODS This prospective study included 123 patients who underwent abdominal CT before and after acute care. The all-abdominal and each abdominal muscle areas were divided into eight parts (e.g. rectus abdominis, psoas, and erector spine), and their areas and densities were measured at the third lumbar vertebra level after the patients were discharged and de-identified with blinding to avoid measurement bias. Short physical performance battery (SPPB) was measured at the start and end of in-hospital cardiac rehabilitation. A generalized linear model with patients as random effects was made to investigate skeletal muscle loss during acute care. Multivariate linear regression analysis was also used to assess the relationship between the change in skeletal muscle during acute care and SPPB during in-hospital cardiac rehabilitation. RESULTS The median age of the patients was 70 (interquartile: 58-77) years, and 69.9% (86/123) were men. The median day between acute care from the day of surgery or hospital admission and follow-up CT was 7 (interquartile: 3-8) days. Overall muscle density declined after acute care (estimate value: -3.640, 95% confidence interval [CI]: -4.538 to -2.741), and each abdominal muscle density consistently declined (interaction: F value = 0.099, P = 0.998). In contrast, there was no significant change in the overall muscle area (estimate value: -0.863, 95% CI: -2.925 to 1.200). Changes in the muscle area were different for each skeletal muscle (interaction: F value = 2.142, P = 0.037), and only the erector spine muscle significantly declined (estimate value: -1.836, 95% CI: -2.507 to -1.165). After adjusting for confounding factors, a greater decline in muscle density was associated with lower recovery score on SPPB (β = 0.296, 95% CI: 0.066 to 0.400). CONCLUSIONS Muscle density consistently declined after acute care, especially the erector spine muscles, which also significantly decreased in size. A higher decline in muscle density was associated with a slower recovery of physical function during in-hospital cardiac rehabilitation in patients with aortic diseases.

The Prevalence of Metabolic Dysfunction-Associated Fatty Liver Disease and Its Association with Physical Function and Prognosis in Patients with Acute Coronary Syndrome. J Clin Med 2022; 11:jcm11071847.

Abstract
It is believed that patients with acute coronary syndrome (ACS) are at an increased risk of nonalcoholic fatty liver disease (NAFLD), which can lead to sarcopenia and physical dysfunction. However, the relationship between metabolic dysfunction-associated fatty liver disease (MAFLD) and physical dysfunction and prognosis remains unclear. We investigated the prevalence of MAFLD in patients with ACS to assess the relationship between MAFLD and muscle strength, walking speed, and 6-min walking distance (6 MWD). We reviewed patients with ACS who were assessed for hepatic steatosis using the fatty liver index, and the results were further assessed to determine the presence of MAFLD. Among 479 enrolled hospitalized patients, MAFLD was identified in 234 (48.9%) patients. Multiple regression analysis revealed that MAFLD was independently associated with lower leg strength, gait speed, and 6 MWD (leg strength, p = 0.020; gait speed, p = 0.003 and 6 MWD, p = 0.011). Furthermore, in multivariate Poisson regression models after adjustment for clinical confounding factors, combined MAFLD and reduced physical functions were significantly associated with a higher incidence of clinical events. MAFLD is common in hospitalized patients with ACS and is associated with impaired physical function. Also, the coexistence of MAFLD and lower physical function predict the incidence of clinical events in patients with ACS.

Abstract
INTRODUCTION Although diabetes mellitus (DM) increases the risk of proteinuria, the relationship between prediabetes and proteinuria remains not fully understood. Further, whether the change in glucose is associated with the risk for proteinuria is unknown. METHODS This was a retrospective cohort study that included 1,849,074 participants (median age, 45 years; 59.3% men). No participants were taking glucose-lowering medications, and none had positive proteinuria at the initial health check-up. Each participant was categorized into three groups: normal (hemoglobin A1c [HbA1c] of <5.7%, n = 1,563,121), prediabetes (HbA1c of 5.7-6.4%, n = 253,490), and DM (HbA1c of ≥6.5%, n = 32,463) groups. We investigated the association between each HbA1c category and incident proteinuria using Cox proportional hazards models. We analyzed the association between the annual change in HbA1c and the risk for proteinuria. RESULTS A total of 65,954 participants developed proteinuria during the observation period. Not only DM (hazard ratio [HR]: 2.15, 95% confidence interval [CI]: 2.07-2.24) but also prediabetes (HR: 1.14, 95% CI: 1.12-1.17) was associated with a greater risk for proteinuria. The relative risk reduction for proteinuria that was associated with prediabetes and DM was 12.3% and 53.5%, respectively. An annual increase in HbA1c was associated with a greater risk for proteinuria. This association was more pronounced in participants having prediabetes. CONCLUSION Not only DM but also prediabetes increased the risk for proteinuria. The influence of change in HbA1c on incident proteinuria was pronounced in people with prediabetes. Optimizing glucose would provide more benefit to individuals having prediabetes for proteinuria prevention.
