Abstract
Aims There have been no investigations of the prevalence and clinical implications of coexistence of anaemia and frailty in older patients hospitalized with heart failure (HF) despite their association with adverse health outcomes. The present study was performed to determine the prevalence and prognostic value of the coexistence of anaemia and frailty in hospitalized older patients with HF. Methods and results We performed post hoc analysis of consecutive hospitalized HF patients ≥65 years old enrolled in the FRAGILE‐HF, which was the prospective, multicentre, observational study. Anaemia was defined as haemoglobin < 13 g/dL in men and <12 g/dL in women, and frailty was evaluated according to the Fried phenotype model. The study endpoint was all‐cause mortality. Of the total of 1332 patients, 1217 (median age, 81 years; 57.4% male) were included in the present study. The rates of anaemia and frailty in the study population were 65.7% and 57.0%, respectively. The patients were classified into the non‐anaemia/non‐frail group (16.6%), anaemia/non‐frail group (26.4%), non‐anaemia/frail group (17.7%), and anaemia/frail group (39.3%). A total of 144 patients died during 1 year of follow‐up. In multivariate analyses, only the anaemia/frail group showed a significant association with elevated mortality rate (adjusted hazard ratio, 1.94; 95% confidence interval, 1.02–3.70; P = 0.043), compared with the non‐anaemia/non‐frail group after adjusting for other covariates. Conclusions Coexistence of anaemia and frailty are prevalent in hospitalized older patients with HF, and it has a negative impact on mortality.

Abstract
Abstract
Background
Respiratory muscle weakness (RMW), frequently observed in patients with cardiovascular disease (CVD), is documented as a predictor for exercise intolerance and poor prognosis. On the other hand, frailty is commonly associated with disease condition, leading to increased risk of morbidity and mortality. Although the developmental mechanism of RMW and frailty is partly similar, the relationship between these statuses remains unclear.
Purpose
We aimed to investigate the correlation between RMW and frailty and its impact on prognosis in patients with CVD.
Methods
We studied 771 consecutive patients (68.5±13.1 years, 256 females) who were hospitalized for CVD treatment and underwent cardiac rehabilitation during hospitalization. Patients who received thoracic surgery within the last 3 months or could not perform respiratory function test were excluded from this study. As patient characteristics, we obtained body mass index, comorbidity conditions, smoking history, blood examinations, echocardiographical variables, and lung function from medical database. The frailty status on admission was assessed using frailty score consisting of 5 items including gait speed, nutrition/shrinking, physical activity, forgetfulness, and emotions/exhaustion, and patients who had 3 items were defined as frailty. We also measured maximal inspiratory pressure (PImax) as respiratory muscle strength at hospital discharge, and RMW was defined with PImax <70% of predicted value. Primary end-point was all-cause clinical events including all-cause death and/or unplanned readmission after hospital discharge. We examined the prevalence of RMW and frailty and the correlation between these statuses. The relationships of RMW with the clinical events for each presence or absence of frailty were also investigated using multivariate Cox proportional hazard models.
Results
RMW and frailty were defined in 163 (33.5%) and 126 (28.7%) patients, respectively, and 95 patients (12.4%) among them showed an overlap of both statuses (Figure 1). Frailty was detected as a significant indicator of RMW after adjusting for confounding factors (adjusted odds ratio: 1.57, 95% CI: 1.12–2.19, P=0.009). Over the median follow-up periods of 1.2 years, all-cause clinical events occurred in 154 patients (20.0%). RMW was significantly and independently associated with increased incidence of all-cause clinical events in patients with both non-frailty (adjusted hazard ratio [HR]: 1.64, 95% CI: 1.09–2.46, P=0.017) and frailty (adjusted HR: 1.97, 95% CI: 1.14–3.42, P=0.015) even after adjusting for clinical confounding factors (Figure 2).
Conclusions
This study is the first to demonstrate that RMW correlated to frailty in patients with CVD, and 12.4% of patients had overlap status. Moreover, RMW was significantly associated with an increased risk of all-cause clinical events in patients with CVD and frailty.

Abstract
Aims The area of the pupil can be used as an indicator of autonomic function. However, the relation between pupil area and prognosis in heart failure (HF) patients remains unclear. This study was performed to examine whether pupil area can be used as a prognostic indicator in patients with HF. Methods and results This retrospective review was performed in 870 consecutive patients (mean age: 67.0 ± 14.1 years, 37.0% women) hospitalized for acute HF. Pupil area was measured with a pupilometer at least 7 days after hospitalization for HF. The primary endpoint was all‐cause mortality, and the secondary endpoint was readmission due to HF. A total of 131 patients died, and 328 patients were readmitted because of HF over a median follow‐up of 1.9 (interquartile range: 1.0–3.7 years) years. After adjustment for several pre‐existing prognostic factors, including Seattle Heart Failure Score (SHFS), pupil area was shown to be independently associated with all‐cause mortality (hazard ratio: 0.72; 95% confidence interval: 0.59–0.88; P = 0.001) and readmission due to HF (hazard ratio: 0.82; 95% confidence interval: 0.73–0.93; P = 0.003). Addition of pupil area to SHFS significantly increased the area under the receiver‐operating characteristic curve for all‐cause mortality (0.69 vs. 0.72, respectively; P = 0.034). Conclusions Pupil area is an independent predictor of all‐cause mortality and readmission due to HF and adds prognostic information to SHFS in patients with HF. The results presented here suggest that pupil area may be useful as a prognostic marker in patients with HF.

Mineral trioxide aggregate suppresses pro-inflammatory cytokine expression via the calcineurin/nuclear factor of activated T cells/early growth response 2 pathway in lipopolysaccharide-stimulated macrophages. Int Endod J 2020; 53:1653-1665.

Abstract
AIM To elucidate mechanisms by which mineral trioxide aggregate (MTA) suppresses pro-inflammatory cytokine mRNA expression in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. METHODOLOGY Mineral trioxide aggregate extracts were prepared by immersing set ProRoot MTA in culture medium. RAW264.7 cells were cultured in the presence of LPS and MTA extracts. mRNA expression levels of interleukin (IL)-1α, IL-6, early growth response 2 (Egr2), suppressor of cytokine signalling 3 (Socs3) and IL-10 were quantified with reverse transcription-quantitative polymerase chain reaction. Phosphorylation of nuclear factor-kappa B (NF-κB) p65 in RAW264.7 cells was analysed by Western blotting. Intracellular calcium imaging was performed with Fluo-4 AM. The activity of nuclear factor of activated T cells (NFAT) was determined by luciferase assays. Enforced expression and silencing of Egr2 in RAW264.7 cells were carried out using an expression vector and specific RNAi, respectively. In vivo kinetics of Egr2+ cells in MTA-treated rat molar pulp tissues were examined using immunohistochemistry. Data were analysed by one-way analysis of variance, followed by the Tukey-Kramer test (P < 0.05). RESULTS Exposure to MTA extracts resulted in reduced mRNA expression levels of IL-1α and IL-6, as well as reduced expression of phosphorylated NF-κB, in LPS-stimulated RAW264.7 cells. Exposure to MTA extracts induced Ca2+ influx, which was blocked by NPS2143, an antagonist of calcium-sensing receptor (CaSR); Ca2+ influx then triggered activation of calcineurin/NFAT signalling and enhanced mRNA expression of Egr2. Enforced expression of Egr2 in RAW264.7 cells promoted the expression of both IL-10 and Socs3. In vivo application of MTA onto rat molar pulp tissue resulted in the appearance of Egr2-expressing cells that coexpressed CD163, a typical M2 macrophage marker. CONCLUSIONS Mineral trioxide aggregate extracts induced downregulation of IL-1α and IL-6 in LPS-stimulated RAW264.7 cells via CaSR-induced activation of calcineurin/NFAT/Egr2 signalling and subsequent upregulation of IL-10 and Socs3.

Abstract
We herein report that sulfur and nitrogen co-doped hollow spherical carbon particles can be applied to oxygen reduction reaction (ORR) electrocatalysts prepared by calcination of polydopamine (PDA) hollow particles. The hollow structure of PDA was formed by auto-oxidative interfacial polymerization of dopamine at the oil and water interface of emulsion microdroplets. The PDA was used as the nitrogen source as well as a platform for sulfur-doping. The obtained sulfur and nitrogen co-doped hollow particles showed a higher catalytic activity than that of nonsulfur-doped particles and nonhollow particles. The high ORR activity of the calcined S-doped PDA hollow particles could be attributed to the combination of nitrogen and sulfur active sites and the large surface areas owing to a hollow spherical structure.

Abstract
BACKGROUND This study was performed to test the hypothesis that low quadriceps isometric strength (QIS) is associated with greater risk of mortality and has the additive prognostic significance to the severity of heart failure (HF) and gait speed in older patients with HF. METHODS A retrospective cohort study was performed in 1273 patients ≥ 60 years of age with HF (mean age 75 ± 8 years, 59.1% men); all of whom were evaluated during hospitalization for usual gait speed and maximal QIS. The QIS was expressed relative to body mass (% BM). The endpoint was all-cause mortality. RESULTS Over a median follow-up period of 1.59 years (interquartile range, 0.58 to 3.42 years), 224 patients died. The cutoff value based on the Youden index for the QIS discriminating those at high risk of mortality was 36.2% BM for overall, and we defined less than this cutoff point of QIS as low QIS. After adjustment for the HF risk score, the hazard ratio in low QIS was 1.55 for overall (95% confidence interval [CI], 1.17-2.06). The addition of low QIS to the HF risk score and gait speed was associated with significant increases in both net reclassification improvement (NRI, 0.239 for overall; 95% CI, 0.096-0.381) and integrated discrimination improvement (IDI, 0.004 for overall; 95% CI, 0.001-0.009) for all-cause mortality. CONCLUSION Low QIS was strongly associated with poor prognosis and showed complementary prognostic predictive capability to the HF risk score and gait speed in older patients with HF.

Abstract
OBJECTIVE In patients with kidney transplant (KT), frailty is a predictor of adverse outcomes. Outcomes of exercise therapy in patients with KT, particularly the efficacy of early exercise after KT, have not been evaluated. We investigated the effect of exercise intervention beginning early after KT on physical performance, physical activity, quality of life, and kidney function in patients with KT. METHODS KT recipients who underwent surgery with usual care plus exercise training from a prospective cohort (exercise group; n = 10) and those with usual care alone from a historical cohort (control group; n = 14) were included in this study. Early exercise comprised supervised aerobic training and physical activity instruction from day 6 to 2 months after KT. The following outcomes were measured: 6-minute walking distance, isometric knee extensor strength, gait speed, physical activity, quality of life, and estimated glomerular filtration rate. RESULTS Analyses of covariance, adjusted for baseline values, revealed significant mean differences between exercise and control groups at 2 months after KT in 6-minute walking distance (+44.4 m, P = .03) and isometric knee extensor strength (+8.1%body weight, P = .03). No significant between-group differences were found in gait speed, physical activity, and quality of life. The analysis of variance for comparison of the area under the recovery curves of estimated glomerular filtration rate after KT revealed no significant difference between groups. CONCLUSION Supervised aerobic training and physical activity instruction initiated in the early phase after KT can improve physical performance without adversely affecting kidney function.

Abstract
The simplified frailty scale is a simple frailty assessment tool modified from Fried's phenotypic frailty criteria, which is easy to administer in hospitalized patients. The applicability of the simplified frailty scale to indicate prognosis in elderly hospitalized patients with cardiovascular disease (CVD) was examined.This cohort study was performed in 895 admitted patients ≥ 65 years (interquartile range, 71.0-81.0, 541 men) with CVD. Patients were classified as robust, prefrail, or frail based on the five components of the simplified frailty scale: weakness, slowness, exhaustion, low activity, and weight loss. The primary endpoint was the composite outcome of all-cause mortality and unplanned readmission for CVD.Patients positive for greater numbers of frailty components showed higher risk of all-cause mortality or unplanned CVD-related readmission (P for trend < 0.001). Classification as both frail (adjusted HR: 3.27, 95% confidence interval [CI]: 1.49-7.21, P = 0.003) and prefrail (adjusted HR: 2.19, 95% CI: 1.00-4.79, P = 0.049) independently predicted the composite endpoint compared with robust after adjusting for potential confounding factors. The inclusion of prefrail, frail, and number of components of frailty increased both continuous net reclassification improvement (0.113, P = 0.049; 0.426, P < 0.001; and 0.321, P < 0.001) and integrated discrimination improvement (0.007, P = 0.037; 0.009, P = 0.038; and 0.018, P = 0.002) for the composite endpoint.Higher scores on the simplified frailty scale were associated with increased risk of mortality or readmission in elderly patients hospitalized for CVD.

Abstract
BACKGROUND & AIMS The Global Leadership Initiative on Malnutrition (GLIM) published a new international standard for defining malnutrition in 2018. The GLIM criteria were compared with the European Society for Clinical Nutrition and Metabolism (ESPEN) criteria in relation to physical function and mortality risk in patients with cardiovascular disease (CVD). METHODS A total of 921 CVD patients ≥ 20 years old (67.8 ± 13.4 years, 631 men) hospitalised for heart failure, acute coronary syndrome and other conditions were stratified according to the presence or absence of malnutrition according to the GLIM and ESPEN criteria. Physical function was assessed by measuring grip strength, 6-minute walking distance and quadriceps isometric strength before hospital discharge, and the endpoint was all-cause mortality. RESULTS During the median follow-up period of 2.3 years (interquartile range, 0.9-3.5 years), 194 deaths occurred in the study population. Malnutrition defined by the GLIM criteria was significantly associated with low physical function. Malnutrition defined by both the GLIM and ESPEN criteria was significantly related to all-cause mortality (P < 0.05). CONCLUSIONS Malnutrition defined according to the GLIM criteria was a predictor of both low physical function and mortality in patients with CVD.

Abstract
Although the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) is useful to assess decline of instrumental activities of daily living (IADL) in Japanese individuals, limited data are available in patients with heart failure (HF). This study was performed to investigate the prognostic value of IADL evaluated by TMIG-IC in initial HF hospitalization patients aged ≥ 65 years. We reviewed 297 elderly HF patients with independent basic ADL before hospitalization. Patients with prior HF were excluded. Five TMIG-IC items were investigated as IADL parameters. Patients with full IADL scores were defined as "independent" and others were defined as "dependent". The endpoint was all-cause mortality, and multivariable analysis was performed to identify IADL risk. The median age was 76 years, and 55% of the patients were male. Forty-one deaths occurred over a median follow-up period of 1.01 years. After adjusting for existing risk factors, including Seattle Heart Failure Score, dependent patients had higher mortality risk than independent patients [hazard ratio 3.64, 95% confidence interval (CI) 1.57-8.43], and mortality risk decreased by 16% for each 1-point increase in IADL score (hazard ratio 0.84, 95% CI 0.71-0.99). In conclusion, limited IADL indicated by TMIG-IC was associated with poorer long-term mortality rate in elderly patients with HF. This inexpensive and easily applicable tool will support decision making in cardiac rehabilitation.

Abstract
Abstract
OBJECTIVES
Although skeletal muscle density (SMD) is useful for predicting mortality, the cut-off in an acute clinical setting is unclear, especially in patients with cardiovascular disease (CVD). This study was performed to determine the preoperative SMD cut-off using the psoas muscle and to investigate the effect on postoperative outcomes, including sarcopaenia, in CVD patients.
METHODS
Preoperative psoas SMD was measured by abdominal computed tomography in CVD patients. Postoperative sarcopaenia was defined according to the criteria of the Asia Working Group for Sarcopaenia. The Youden index was used to test the predictive accuracy of survival models. The prognostic capability was evaluated using multivariable survival and receiver operating characteristic curve analyses.
RESULTS
Continuous data were available for 1068 patients (mean age 65.5 years; 63.6% male). A total of 105 (9.8%) deaths occurred during the 1.99-year median follow-up period (interquartile range 0.71–4.15). The psoas SMD cut-off estimated by the Youden index was 45 Hounsfield units with high sensitivity and moderate specificity for all-cause mortality and was consistent in various stratified analyses. After adjusting for the existing prognostic model, EuroSCORE II, preoperative and postoperative physical status, psoas SMD cut-off was predicted for mortality (hazard ratio 2.42, 95% confidence interval 1.32–4.45). The psoas SMD cut-off was also significantly associated with postoperative sarcopaenia and provided additional prognostic information to EuroSCORE II on receiver operating characteristic curve analysis (area under the curve 0.627 vs 0.678, P = 0.011).
CONCLUSIONS
Reduced psoas SMD was associated with postoperative mortality and added information prognostic for mortality to the existing prognostic model in CVD patients.

Abstract
PURPOSE The purpose of this study was to determine whether gait speed affects the obesity paradox in older patients with cardiovascular disease. METHODS The study population consisted of 2224 patients ≥60 years old with cardiovascular disease admitted to hospital between May 1, 2006, and January 31, 2018. Body mass index (BMI) and gait speed before hospital discharge were determined, and patients were divided into two groups: slow and preserved gait speed (≤0.8 and >0.8 m/s, respectively), according to the algorithm for sarcopenia diagnosis. The slow and preserved gait speed groups were also further subdivided according to BMI: <18.5 kg/m2, 18.5-24.9 kg/m2, and BMI ≥25.0 kg/m2. The study endpoint was all-cause mortality. RESULTS The study population (male: 66.7%) had a mean age of 73.1 ± 7.6 years. Over a median follow-up period of 1.69 years (interquartile range 0.67-3.67 years), 283 patients died. Higher BMI was associated with favorable prognosis in the group with preserved gait speed but not in the group with slow gait speed after adjusting for other prognostic factors. Adding BMI to the clinical model significantly increased the area under the receiver operating characteristic curve in the group with preserved gait speed (0.744 vs 0.726, P = 0.028) but not in the group with slow gait speed (0.716 vs 0.716, P = 0.789). CONCLUSIONS Higher BMI was consistently associated with favorable prognosis in patients with cardiovascular disease and preserved gait speed but not in those with slow gait speed. These findings indicated that physical frailty influences the obesity paradox in older patients with cardiovascular disease.

Prevalence and prognosis of respiratory muscle weakness in heart failure patients with preserved ejection fraction. Respir Med 2019; 161:105834. [PMID: 31783270 DOI: 10.1016/j.rmed.2019.105834] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Revised: 11/16/2019] [Accepted: 11/18/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND Although respiratory muscle weakness (RMW) is known to predict prognosis in patients with heart failure with reduced ejection fraction (HFrEF), RMW prevalence and its prognosis in those with preserved ejection fraction (HFpEF) remain unknown. We aimed to investigate whether the RMW predicted mortality in HFpEF patients. METHODS We conducted a single-centre observational study with consecutive 1023 heart failure patients (445 in HFrEF and 578 in HFpEF). Maximal inspiratory pressure (PImax) was measured to assess respiratory muscle strength at hospital discharge, and RMW was defined as PImax <70% of predicted value. Endpoint was all-cause mortality after hospital discharge, and we examined the influence of RMW on the endpoint. RESULTS Over a median follow-up of 1.8 years, 134 patients (13.1%) died; of these 53 (11.9%) were in HFrEF and 81 (14.0%) in HFpEF. RMW was evident in 190 (42.7%) HFrEF and 226 (39.1%) HFpEF patients and was independently associated with all-cause mortality in both HFrEF (adjusted hazard ratio [HR]: 2.13, 95% confidence interval [CI]: 1.17-3.88) and HFpEF (adjusted HR: 2.85, 95% CI: 1.74-4.67) patients. Adding RMW to the multivariate logistic regression model significantly increased area under the receiver-operating characteristic curve (AUC) for all-cause mortality in HFpEF (AUC including RMW: 0.78, not including RMW: 0.74, P = 0.026) but not in HFrEF (AUC including RMW: 0.84, not including RMW: 0.82, P = 0.132). CONCLUSIONS RMW was observed in 39% of HFpEF patients, which was independently associated with poor prognosis. The additive effect of RMW on prognosis was detected only in HFpEF but not in HFrEF.

Abstract
Background
Stroke and cardiovascular disease are one of the leading causes of death and disability in Japan. In order to investigate current burden, we conduct a population-based registry of cardiovascular disease in Shiga Prefecture, Japan since 2012. We will demonstrate challenges in conduct of the registry study.
Methods
In 2012, we established the Shiga Stroke Registry (SSR), a multicenter population-based registry study designed to build a complete information system for the management of stroke in Shiga Prefecture, Japan. The registry uses local monitoring, combined with remote data collection and quality control systems, to create an integrated surveillance system among a network of all acute care hospitals with neurology/neurosurgery facilities and smaller hospitals with rehabilitation facilities in the region. In 2019, study name has changed to Shiga Stroke and Heart Attack Registry (SSHR) and additional registration of coronary heart disease and aortic disease have started. Each case is reviewed and adjudicated by 2 or more specialists.
Results
In the financial year of 2018 (from April to March), a total of 4809 stroke cases were identified. From December 2018 to April 2019, a total of 515 coronary heart and aortic diseases were identified. A total 10 nurses work full-time for the registry and it takes average of 1 hour to collect information for each patient. Challenges in conduct of the cardiovascular registry involve regulatory and ethical approval, funding, associations with local hospitals, non-standardized hospital diagnosis, staff training for comprehensive data collection including pathophysiology, examination and treatment, and quality control of data collection.
Conclusions
SSHR is a population-based registry of wide range of stroke and cardiovascular disease in Shiga Prefecture, Japan. In order to keep quality of the data, we put a lot of efforts on staff training and quality control.

Abstract
Abstract
Background
In elderly people, a decline in activities of daily living is more closely associated with low muscle strength (dynapenia) than with low muscle mass. Moreover, the combination of low muscle strength and obesity (dynapenic obesity) is associated with a higher risk of mortality than dynapenia or obesity alone, but its influence on prognosis is still unknown in elderly heart failure (HF) patients. To clarify these relationships may contribute to the development of rehabilitation programs for elderly HF patients and the improvement their prognoses in the future.
Purpose
We aimed to investigate the influence of dynapenia and obesity on prognoses of elderly HF patients.
Methods
We evaluated 1006 elderly HF patients aged ≥65 years (76.5±6.9 years, 579 males) who were admitted to our hospital and participated in an inpatient cardiac rehabilitation program. We assessed patients' characteristics, including body mass index (BMI) and handgrip strength during hospitalization. Patients with low handgrip strength (<26 kg and <18 kg in males and females, respectively) and high BMI (≥25 kg/m2) were considered to have dynapenia and obesity, respectively. Moreover, patients fulfilling the above two criteria (dynapenia, obesity) were considered to have dynapenic obesity. Patients were divided into four groups: normal, dynapenia only, obesity only, and dynapenic obesity. We compared survival rates among the four groups using the Kaplan-Meier method and log-rank test. To identify predictors for all-cause mortality, we performed Cox regression analysis.
Results
During the 8-year follow-up period, 228 patients (21.2%) died. Eight-year cumulative incidences of mortality were 35.4%, 26.0%, 62.6%, and 33.1% in the normal, obesity only, dynapenia only, and dynapenic obesity groups, respectively. Significantly lower survival rates were observed in the dynapenia only group than in the other 3 groups (log-rank: 28.893, P<0.001). Cox regression analysis, after adjusting for age and sex, showed significantly poor prognosis in the dyanapenia only group than in the other 3 groups (normal group, hazard ratio [HR] = 0.684, 95% confidence interval [CI] = 0.488–0.959, P=0.028; obesity only group, HR = 0.330, 95% CI = 0.182–0.598, P<0.001; dynapenic obesity group, HR = 0.390, 95% CI = 0.206–0.739, P=0.004).
Conclusion
Elderly HF patients with dynapenia alone had poor prognoses. Obesity may have protective effects on the survival of dynapenia patients with HF.

Abstract
Abstract
Background
Autonomic dysfunction is among the most important pathophysiological factors involved in the high mortality rate associated with cardiovascular disease (CVD). Autonomic function is generally evaluated by heart rate variability, which is obtained by Holter electrocardiography. However, the measurement of heart rate variability requires continuous electrocardiographic monitoring for 24 h, which is time consuming and not always feasible. The pupillary area is controlled by the autonomic nervous system; however, limited data are available regarding the utility of the pupillary area for predicting prognosis in patients with CVD.
Purpose
We aimed to investigate whether pupillary area can be used as a novel prognostic marker in patients with CVD.
Methods
We retrospectively reviewed 1342 consecutive Japanese patients hospitalized for CVD. 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 University Hospital. The pupillary area measurement was performed on both eyes at least 7 days after hospitalization for CVD using a portable videopupillography system (Iriscorder Dual C10641; Hamamatsu Photonics, Hamamatsu, Japan) consisting of a goggle-shaped measurement portion with a charge-coupled device camera and a control portion with a video monitor and microcomputer with software for data analysis. After securing the goggles on the patient's face and fully covering the patient's eyes, a 5-minute period was allowed for dark adaptation. All patients were tested once between 09:00 and 12:00 h. The primary outcome of this study was all-cause mortality, and the endpoint time was calculated as the number of days from the date of pupillary area measurement up to three years. We performed the Kaplan–Meier and log-rank tests and multivariable Cox regression analysis to evaluate the prognostic predictive capability of the pupillary area.
Results
The study population had a mean age of 65±13 years, and 69.4% of the patients were male. The median of the pupillary area was 18.5 mm2 (interquartile range: 13.3–23.4 mm2). Over a median follow-up period of 1.9 years (interquartile range: 1.0–3.0 years), a total of 114 deaths occurred in the patient population. The Kaplan–Meier and log-rank tests revealed that all-cause mortality was significantly higher in the small pupillary area group than in the large pupillary area group (P<0.0001, Figure). Furthermore, Cox regression analysis indicated that the pupillary area was an independent predictor of mortality (Hazard ratio: 0.96; 95% confidence interval: 0.93–0.98; P=0.006) even after adjusting for several preexisting prognostic factors.
Kaplan-Meire Curve
Conclusion
The pupillary area can be an independent predictor of prognosis in patients with CVD, and our observations suggest that the assessment of the pupillary area can be useful as a new noninvasive prognostic predictor in patients with CVD.

Abstract
Abstract
Background
Respiratory muscle weakness, frequently observed in patients with chronic heart failure (CHF), has been documented as a predictor for poor prognosis. Several studies have reported that respiratory muscle training increases respiratory muscle strength and consequently improves exercise tolerance and quality of life in these patients. However, the relationship between the change in respiratory muscle strength and prognosis is still unclear.
Purpose
We aimed to investigate whether the change in respiratory muscle strength following cardiac rehabilitation predicts the incidence of clinical events in CHF patients.
Methods
We studied 348 patients with CHF who were hospitalized because of decompensated heart failure and received 5-month cardiac rehabilitation during hospitalization and after hospital discharge. Clinical characteristics including aetiology of heart failure, comorbidity conditions, medications, blood examination and echocardiographic variables were obtained from clinical records. We also measured maximal inspiratory pressure (PImax) as respiratory muscle strength at hospital discharge and 5 months later. The change of PImax (ΔPImax) between the 5-month observation period was examined. We followed up the patients after the observation period and investigated the incidence of all-cause mortality or all-cause unplanned readmission. In statistical analysis, patients were divided into two groups based on the median value of ΔPImax. We compared the event-free survival rate between the two groups using the Kaplan-Meier method with a log-rank test. We also performed the Cox proportional hazard model to clarify whether the ΔPImax was an independent predictor for the incidence of clinical events.
Results
Over a median follow-up of 1.6 years, 121 patients (34.8%) died or readmitted, and their rate of incidence was 21.7/100 person-years. The higher ΔPImax was associated significantly with a higher rate of event-free survival (Log-rank: 8.085, P=0.004, Figure 1). In univariate Cox proportional hazard model, ΔPImax was a significant predictor for the all-cause mortality/readmission (unadjusted hazard ratio for PImax increase of 10 cmH2O: 0.842, 95% CI: 0.763 - 0.931, P=0.001). Even after adjustment for clinical confounding factors including baseline PImax, ΔPImax remained significant and independent predictor for the all-cause mortality/readmission (adjusted hazard ratio for PImax increase of 10 cmH2O: 0.862, 95% CI: 0.763 - 0.974, P=0.017, Figure 2).
Conclusion
This study is the first to demonstrate that the change in respiratory muscle strength following cardiac rehabilitation independently predicts the incidence of clinical events in patients with CHF. The increase in PImax of 10 cmH2O was associated significantly with a 14% decrease in the rate of all-cause mortality or readmission.

Abstract
Abstract
Background
Atrial fibrillation (AF) is known as a common arrhythmia in heart failure patients with preserved left ventricular ejection fraction (HFpEF). Several studies have reported that HFpEF patients with AF show lower exercise tolerance and poorer prognosis as compared with those with sinus rhythm (SR). On the other hand, exercise training is documented to improve peripheral muscle function and exercise tolerance in HFpEF patients. However, the relationship between AF status and outcomes due to exercise training is still unclear in these patients.
Purpose
We aimed to investigate the influence of AF on the responses to outcomes with exercise training in HFpEF patients.
Methods
We studied 426 patients with HFpEF who received 5-month cardiac rehabilitation including exercise training during hospitalization and after hospital discharge. As clinical characteristics, we obtained body mass index, disease aetiology, comorbidity conditions, blood examination and echocardiographic variables from medical records. We also measured isometric quadriceps strength (QS) and 6-minute walk distance (6MWD) as peripheral muscle strength and exercise tolerance, respectively. The QS and 6MWD were assessed at hospital discharge as the baseline and 5 months later. AF status was determined by the presence on electrocardiogram at baseline 6MWD or medical history of AF during hospitalization. In statistical analysis, we compared baseline clinical characteristics, QS and 6MWD between the rhythm status (SR group or AF group). We also examined the changes in QS and 6MWD from baseline to the 5-month observation period (ΔQS and Δ6MWD) and compared them between the 2 groups using analysis of covariance with adjustment for baseline clinical confounding factors.
Results
At baseline, 289 patients (68%) were in SR, and 111 patients (26%) had AF. The AF was associated significantly with older age (P<0.001) and lower levels of estimated glomerular filtration rate (P=0.013), QS (P<0.001) and 6MWD (P<0.001) at baseline. The QS increased significantly from 25.2±11.0 kg at baseline to 30.8±13.0 kg after 5-month cardiac rehabilitation in the SR group, and from 21.1±8.3 kg to 26.0±9.4 kg in the AF group (P<0.001, respectively). The 6MWD also increased significantly from 394.8±129.2 to 463.5±133.5 meters in the SR, and from 343.7±107.9 to 403.0±114.5 meters in the AF (P<0.001, respectively). There were no significant differences in ΔQS and Δ6MWD between the SR and AF groups even after adjustment for clinical confounding factors including baseline QS or 6MWD (Figure).
Conclusions
The AF status in HFpEF patients was associated with older age, lower peripheral muscle function and also lower exercise tolerance at baseline, but not associated with the responses to exercise training.

Abstract
BACKGROUND Evidence for the prognostic value of gait speed is largely based on a single measure at baseline, so we investigated the prognostic significance of change in gait speed in hospitalized older acute heart failure (AHF) patients.Methods and Results:This retrospective study was performed in a cohort of 388 AHF patients ≥60 years old (mean age: 74.8±7.8 years, 228 men). Routine geriatric assessment included gait speed measurement at baseline and at discharge. The primary outcome of this study was all-cause death. Gait speed increased from 0.74±0.25 m/s to 0.98±0.27 m/s after 13.5±11.0 days. Older age, shorter height and lower hemoglobin level at admission, prior HF admission, and higher baseline gait speed were independently associated with lesser improvement in gait speed. A total of 80 patients died and 137 patients were readmitted for HF over a mean follow-up period of 2.1±1.9 years. In multivariate analyses, change in gait speed showed inverse associations with all-cause death (hazard ratio [HR] per 0.1 m/s increase: 0.83; 95% confidence interval [CI]: 0.73 to 0.95; P=0.006) and with risk of readmission for HF (HR: 0.91; 95% CI: 0.83 to 0.99; P=0.036). CONCLUSIONS Short-term improvement in gait speed during hospitalization was associated with reduced risks of death and readmission for HF in older patients with AHF.

Abstract
BACKGROUND AND PURPOSE The association between an increased supraventricular ectopic beat (SVEB) and subclinical cerebrovascular disease remains unclear. Given the emerging concept that an increased SVEB is a marker of atrial cardiomyopathy or atherosclerosis burden, we sought to determine whether excessive supraventricular ectopic activity (ESVEA) is associated with a higher burden of subclinical cerebrovascular disease in the middle-aged to older cohort with neither apparent stroke nor atrial fibrillation. METHODS We conducted a cross-sectional population-based study of 462 men (mean age, 68.1 years) who underwent 24-h Holter electrocardiography and brain magnetic resonance imaging. ESVEA was defined as the presence of >10 SVEBs/h. Subclinical cerebrovascular diseases were defined as silent brain infarct (SBI), white matter hyperintensity (WMH) and intracranial atherosclerotic stenosis (ICAS). The association of ESVEA with the presence of subclinical cerebrovascular diseases was adjusted for potential confounding covariates. RESULTS A total of 88 (19.0%) participants had ESVEA and 81 (17.5%), 91 (19.7%) and 109 (23.6%) had SBI, WMH and ICAS, respectively. In multivariable-adjusted Poisson regression with robust error variance, ESVEA was associated with the presence of WMH (relative risk, 1.58; 95% confidence interval, 1.06-2.36) and ICAS (relative risk, 1.49; 95% confidence interval, 1.02-2.18), but not with that of SBI (relative risk, 1.32; 95% confidence interval, 0.86-2.01). These associations were consistent when the graded distributions of subclinical cerebrovascular diseases were applied as outcomes in ordinal logistic regression. CONCLUSIONS The ESVEA was independently associated with higher burdens of WMH and ICAS. This suggests that increased SVEBs might improve risk stratification of individuals at high risk of subclinical cerebrovascular disease and consequently apparent ischaemic stroke.

Abstract
BACKGROUND Sarcopenic obesity is a health condition involving a combination of excess adipose tissue and loss of muscle mass. Although sarcopenic obesity is known to contribute to the morbidity and mortality of chronic diseases, limited data are available in patients with cardiovascular disease. The present study was performed to examine whether sarcopenic obesity determined by preoperative computed tomography (CT) is a useful predictor of postoperative mortality in patients undergoing cardiovascular surgery. METHODS We reviewed the findings in 664 consecutive cardiovascular surgery patients (mean age, 65.8±12.7 years; male, 66.6%) who underwent preoperative CT including the level of the third lumbar vertebra for clinical purposes. Psoas muscle attenuation (MA) and visceral adipose tissue (VAT) were measured as metrics of sarcopenia and obesity, respectively. Sarcopenia was defined as low MA (below median), while obesity was defined as high VAT (≥103cm2 for males and ≥69cm2 for females). The endpoint was all-cause mortality and secondary outcomes were muscle function. RESULTS After adjusting for age and sex, sarcopenic obesity showed significant associations with lower grip strength and quadriceps strength, slower gait speed, and shorter 6-min walking distance compared to the normal group (p<0.05). On multivariate Cox regression analysis, sarcopenic obesity was associated with increased risk of mortality after adjusting for EuroSCORE (hazard ratio, 3.04; 95% confidence interval, 1.25-7.40). CONCLUSIONS Sarcopenic obesity is associated with poor muscle function and all-cause mortality in patients undergoing cardiovascular surgery.

Abstract
BACKGROUND The detection of impaired physical performance in older adults with cardiovascular disease is essential for clinical management and therapeutic decision-making. There is a requirement for an assessment tool that can be used conveniently, rapidly, and securely in clinical practice for screening decreased physical performance. OBJECTIVE The present study was performed to evaluate the association of office-based physical assessments with decreased physical performance and to compare the prognostic capability of these assessments in older adults with cardiovascular disease. METHODS A total of 1,040 patients aged 75 years and older with cardiovascular disease were included in this analysis. One-leg standing time (OLST) and handgrip strength were measured as office-based physical assessment tools, and short physical performance battery (SPPB), 6-min walk distance, and usual gait speed were also measured at hospital discharge as measurements of physical performance. All-cause mortality was assessed by death registry at the hospital. We examined the association of office-based measures with physical performance and all-cause mortality. RESULTS The areas under the curve of OLST for SPPB < 10, 6-min walk distance < 300 m, and usual gait speed < 1.0 m/s were 0.87 (95% CI 0.83-0.91), 0.83 (95% CI 0.80-0.86), and 0.81 (95% CI 0.78-0.85), respectively. The discrimination abilities of OLST for decreased physical performance were significantly higher than those of handgrip strength. After adjusting for the effects of patient characteristics, the hazard ratio for all-cause mortality in the < 3 s group for OLST was 1.68 (95% CI 1.06-2.67, p = 0.03).
