Socioeconomic and partner status in chronic heart failure: Relationship to exercise capacity, quality of life, and clinical outcomes

Instrumental, Affective, and Patient-Centered Communication Between Cardiologists and Patients with Low Socioeconomic Status: An Observational Study

One of the essential elements in managing health is having adequate communication with health care providers. Unfortunately, patients with a low socioeconomic status (SES) often experience less adequate communication with their doctor. In the current study, we explore and compare the communication of both doctors and patients from lower and higher sociodemographic backgrounds on three factors: instrumental, affective, and patient-centered communication. In total, 45 cardiology consultations were observed, transcribed, and coded (16 low-SES, 16 middle-SES, 13 high-SES). Our analyses showed that, compared to higher-SES patients, low-SES patients voiced less of their concerns, answered questions of the doctor more often with one word, and expressed less utterances overall. Naturally, we found that doctors expressed more utterances overall toward low-SES patients. For doctors, no differences regarding instrumental, affective, or patient-centered communication were found. These findings suggest that low-SES patients are more passive communicators and communication differences based on SES exist predominantly for patients' communication. The revealed communication differences may lead to a less adequate interaction and potentially worse patient outcomes, further increasing the socioeconomic health gap. Hence, doctors should become even more aware of socioeconomic patient communication differences so that they can appropriately encourage low-SES patients to become more active communicators.

Exercise-based cardiac rehabilitation for adults with heart failure

BACKGROUND

People with heart failure experience substantial disease burden that includes low exercise tolerance, poor health-related quality of life (HRQoL), increased risk of mortality and hospital admission, and high healthcare costs. The previous 2018 Cochrane review reported that exercise-based cardiac rehabilitation (ExCR) compared to no exercise control shows improvement in HRQoL and hospital admission amongst people with heart failure, as well as possible reduction in mortality over the longer term, and that these reductions appear to be consistent across patient and programme characteristics. Limitations noted by the authors of this previous Cochrane review include the following: (1) most trials were undertaken in patients with heart failure with reduced (< 45%) ejection fraction (HFrEF), and women, older people, and those with heart failure with preserved (≥ 45%) ejection fraction (HFpEF) were under-represented; and (2) most trials were undertaken in a hospital or centre-based setting.

OBJECTIVES

To assess the effects of ExCR on mortality, hospital admission, and health-related quality of life of adults with heart failure.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO and Web of Science without language restriction on 13 December 2021. We also checked the bibliographies of included studies, identified relevant systematic reviews, and two clinical trials registers.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared ExCR interventions (either exercise only or exercise as part of a comprehensive cardiac rehabilitation) with a follow-up of six months or longer versus a no-exercise control (e.g. usual medical care). The study population comprised adults (≥ 18 years) with heart failure - either HFrEF or HFpEF.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were all-cause mortality, mortality due to heart failure, all-cause hospital admissions, heart failure-related hospital admissions, and HRQoL. Secondary outcomes were costs and cost-effectiveness. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

We included 60 trials (8728 participants) with a median of six months' follow-up. For this latest update, we identified 16 new trials (2945 new participants), in addition to the previously identified 44 trials (5783 existing participants). Although the existing evidence base predominantly includes patients with HFrEF, with New York Heart Association (NYHA) classes II and III receiving centre-based ExCR programmes, a growing body of trials includes patients with HFpEF with ExCR undertaken in a home-based setting. All included trials employed a usual care comparator with a formal no-exercise intervention as well as a wide range of active comparators, such as education, psychological intervention, or medical management. The overall risk of bias in the included trials was low or unclear, and we mostly downgraded the certainty of evidence of outcomes upon GRADE assessment. There was no evidence of a difference in the short term (up to 12 months' follow-up) in the pooled risk of all-cause mortality when comparing ExCR versus usual care (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.71 to 1.21; absolute effects 5.0% versus 5.8%; 34 trials, 36 comparisons, 3941 participants; low-certainty evidence). Only a few trials reported information on whether participants died due to heart failure. Participation in ExCR versus usual care likely reduced the risk of all-cause hospital admissions (RR 0.69, 95% CI 0.56 to 0.86; absolute effects 15.9% versus 23.8%; 23 trials, 24 comparisons, 2283 participants; moderate-certainty evidence) and heart failure-related hospital admissions (RR 0.82, 95% CI 0.49 to 1.35; absolute effects 5.6% versus 6.4%; 10 trials; 10 comparisons, 911 participants; moderate-certainty evidence) in the short term. Participation in ExCR likely improved short-term HRQoL as measured by the Minnesota Living with Heart Failure (MLWHF) questionnaire (lower scores indicate better HRQoL and a difference of 5 points or more indicates clinical importance; mean difference (MD) -7.39 points, 95% CI -10.30 to -4.77; 21 trials, 22 comparisons, 2699 participants; moderate-certainty evidence). When pooling HRQoL data measured by any questionnaire/scale, we found that ExCR may improve HRQoL in the short term, but the evidence is very uncertain (33 trials, 37 comparisons, 4769 participants; standardised mean difference (SMD) -0.52, 95% CI -0.70 to -0.34; very-low certainty evidence). ExCR effects appeared to be consistent across different models of ExCR delivery: centre- versus home-based, exercise dose, exercise only versus comprehensive programmes, and aerobic training alone versus aerobic plus resistance programmes.

AUTHORS' CONCLUSIONS

This updated Cochrane review provides additional randomised evidence (16 trials) to support the conclusions of the previous 2018 version of the review. Compared to no exercise control, whilst there was no evidence of a difference in all-cause mortality in people with heart failure, ExCR participation likely reduces the risk of all-cause hospital admissions and heart failure-related hospital admissions, and may result in important improvements in HRQoL. Importantly, this updated review provides additional evidence supporting the use of alternative modes of ExCR delivery, including home-based and digitally-supported programmes. Future ExCR trials need to focus on the recruitment of traditionally less represented heart failure patient groups including older patients, women, and those with HFpEF.

Which Components of The International Classification of Functioning, Disability and Health (ICF) are Covered by Cardiac Rehabilitation Assessment Tools among Individuals with Heart Failure?

BACKGROUND

The therapeutic assessment of functioning in cardiac rehabilitation from the perspective of the International Classification of Functioning, Disability and Health (ICF) can provide a biopsychosocial approach to health care. However, it is unclear which components are reflected in the instruments used for cardiac rehabilitation in individuals with heart failure (HF).

OBJECTIVES

To investigate which ICF components (body function, structures, activities, participation, environmental factors, and personal factors) are represented in the assessment instruments used in individuals with HF and to identify the most appropriate instrument to use based on the inclusion of these factors.

METHODS

Forty-four clinical trials included in an updated Cochrane systematic review that investigated the effects of exercise-based cardiac rehabilitation in patients with HF were reviewed. The instruments were analyzed to extract significant concepts linked to the ICF codes.

RESULTS

A total of 12 outcomes and 40 instruments were identified. The concepts were linked to 2466 codes in the following ICF components: body functions (41.8%), activities (29.7%), participation (8.4%), environmental factors (3.8%), personal factors (1.3%), and body structures (1.0%); other concepts (13.9%) were classified as not covered by ICF. None of the instruments presented concepts linked to all ICF components. The Minnesota Living with Heart Failure Questionnaire (MLHFQ), however, demonstrated comprehensive coverage of the ICF components, with the exception of body structure.

CONCLUSIONS

Body function was the most frequently detected ICF component. Individual instruments did not provide a comprehensive perspective on the functioning level of individuals with HF. The MLHFQ provided the greatest coverage of ICF components.

Marital status impact on the outcomes of patients admitted for acute decompensation of heart failure: A retrospective, single-center, analysis

BACKGROUND

Conflicting evidence exists regarding the association between marital status and outcomes in patients with heart failure (HF). Further, it is not clear whether type of unmarried status (never married, divorced, or widowed) disparities exist in this context.

HYPOTHESIS

We hypothesized that marital status will be associated with better outcomes in patients with HF.

METHODS

This single-center retrospective study utilized a cohort of 7457 patients admitted with acute decompensated HF (ADHF) between 2007 and 2017. We compared baseline characteristics, clinical indices, and outcomes of these patients grouped by their marital status. Cox regression analysis was used to explore the independency of the association between marital status and long-term outcomes.

RESULTS

Married patients accounted for 52% of the population while 37%, 9%, and 2% were widowed, divorced, and never married, respectively. Unmarried patients were older (79.8 ± 11.5 vs. 74.8 ± 11.1 years; p < 0.001), more frequently women (71.4% vs. 33.2%; p < 0.001), and less likely to have traditional cardiovascular comorbidities. Compared with married patients, all-cause mortality incidence was higher in unmarried patients at 30 days (14.7% vs. 11.1%, p < 0.001), 1 year, and 5 years (72.9% vs. 68.4%, p < 0.001). Nonadjusted Kaplan-Meier estimates for 5-year all-cause mortality by sex, demonstrated the best prognosis for married women, and by marital status in unmarried patients, the best prognosis was demonstrated in divorced patients while the worst was recorded in widowed patients. After adjustment for covariates, marital status was not found to be independently associated with ADHF outcomes.

CONCLUSIONS

Marital status is not independently associated with outcomes of patients admitted for ADHF. Efforts for outcomes improvement should focus on other, more traditional risk factors.

Individual Trajectories of Health Status During the First Year of Discharge From Hospitalization for Heart Failure and Their Associations With Death in the Following Years

Background Improving health status is one of the major goals in the management of heart failure (HF). However, little is known about the long-term individual trajectories of health status in patients with acute HF after discharge. Methods and Results We enrolled 2328 patients hospitalized for HF from 51 hospitals prospectively and measured their health status via the Kansas City Cardiomyopathy Questionnaire-12 at admission and 1, 6, and 12 months after discharge, respectively. The median age of the patients included was 66 years, and 63.3% were men. Six patterns of Kansas City Cardiomyopathy Questionnaire-12 trajectories were identified by a latent class trajectory model: persistently good (34.0%), rapidly improving (35.5%), slowly improving (10.4%), moderately regressing (7.4%), severely regressing (7.5%), and persistently poor (5.3%). Advanced age, decompensated chronic HF, HF with mildly reduced ejection fraction, HF with preserved ejection fraction, depression symptoms, cognitive impairment, and each additional HF rehospitalization within 1 year of discharge were associated with unfavorable health status (moderately regressing, severely regressing, and persistently poor) (P<0.05). Compared with the pattern of persistently good, slowly improving (hazard ratio [HR], 1.50 [95% CI, 1.06-2.12]), moderately regressing (HR, 1.92 [1.43-2.58]), severely regressing (HR, 2.26 [1.54-3.31]), and persistently poor (HR, 2.34 [1.55-3.53]) were associated with increased risks of all-cause death. Conclusions One-fifth of 1-year survivors after hospitalization for HF experienced unfavorable health status trajectories and had a substantially increased risk of death during the following years. Our findings help inform the understanding of disease progression from a patient perception perspective and its relationship with long-term survival.

Patient-Reported Status and Heart Failure Outcomes in Asia by Sex, Ethnicity, and Socioeconomic Status

Background

In heart failure (HF), symptoms and health-related quality of life (HRQoL) are known to vary among different HF subgroups, but evidence on the association between changing HRQoL and outcomes has not been evaluated.

Objectives

The authors sought to investigate the relationship between changing symptoms, signs, and HRQoL and outcomes by sex, ethnicity, and socioeconomic status (SES).

Methods

Using the ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) Registry, we investigated associations between the 6-month change in a "global" symptoms and signs score (GSSS), Kansas City Cardiomyopathy Questionnaire overall score (KCCQ-OS), and visual analogue scale (VAS) and 1-year mortality or HF hospitalization.

Results

In 6,549 patients (mean age: 62 ± 13 years], 29% female, 27% HF with preserved ejection fraction), women and those in low SES groups had higher symptom burden but lower signs and similar KCCQ-OS to their respective counterparts. Malay patients had the highest GSSS (3.9) and lowest KCCQ-OS (58.5), and Thai/Filipino/others (2.6) and Chinese patients (2.7) had the lowest GSSS scores and the highest KCCQ-OS (73.1 and 74.6, respectively). Compared to no change, worsening of GSSS (>1-point increase), KCCQ-OS (≥10-point decrease) and VAS (>1-point decrease) were associated with higher risk of HF admission/death (adjusted HR: 2.95 [95% CI: 2.14-4.06], 1.93 [95% CI: 1.26-2.94], and 2.30 [95% CI: 1.51-3.52], respectively). Conversely, the same degrees of improvement in GSSS, KCCQ-OS, and VAS were associated with reduced rates (HR: 0.35 [95% CI: 0.25-0.49], 0.25 [95% CI: 0.16-0.40], and 0.64 [95% CI: 0.40-1.00], respectively). Results were consistent across all sex, ethnicity, and SES groups (interaction P > 0.05).

Conclusions

Serial measures of patient-reported symptoms and HRQoL are significant and consistent predictors of outcomes among different groups with HF and provide the potential for a patient-centered and pragmatic approach to risk stratification.

Predictors of the Quality of Life of University Students: A Cross-Sectional Study

Quality of life (QOL) is a complex and multifaceted concept that has been used to study different aspects of people's lives, including physical and psychological wellbeing, financial independence, social relationships, personal beliefs and living situation. In this study, we aimed to assess the QOL of a group of Spanish university students and identify associated factors.

METHOD

We completed a cross-sectional study of the QOL of 868 university students using the WHOQOL-BREF questionnaire. In addition, data regarding sociodemographic information and self-esteem (Rosenberg Self-Esteem Scale), physical activity (International Physical Activity Questionnaire-Short version), diet (Spanish Index of Healthy Eating), alcohol consumption (CAGE questionnaire) and sleep quality (Pittsburgh Sleep Quality Index) were collected.

RESULTS

A total of 66.2% of participants assessed their QOL positively, while 58.8% favorably evaluated their overall health. Students reported the highest scores for the physical health domain of QOL, whereas they gave the lowest scores for the psychological health domain. Age was inversely associated with QOL. Higher self-esteem and satisfaction with academic performance, as well as sleep and diet quality, were directly associated with higher QOL. The physical health domain of QOL was scored more highly by participants who had a healthy body weight or those who reported moderate levels of physical activity. Higher scores in the social relationships domain of QOL were directly linked to alcohol intake, smoking and low body weight in addition to being inversely associated with screen time. The psychological domain of QOL was lower for those who were overweight or lived alone.

CONCLUSION

Many sociodemographic, academic and behavioral variables are associated with university students' QOL. The present findings underscore the need to direct further initiatives toward identifying and overcoming barriers to increased QOL for university students.

Gender difference in heart failure with preserved ejection fraction: clinical profiles, examinations, and prognosis

Heart failure with preserved ejection fraction (HFpEF) has currently become a major concern in the aging society owing to its substantial and growing prevalence. Recent investigations regarding sacubitril/valsartan have suggested that there is a gender difference in the efficacy of the medication in HFpEF cohort. However, information of gender difference in clinical profiles, examination, and prognosis have not been well investigated. The present study aimed to evaluate the differences in baseline characteristics and outcomes between women and men in a Japanese HFpEF cohort. We analyzed the data from our prospective, observational, and multicenter cohort study. Overall, 1036 consecutive patients hospitalized for acute decompensated heart failure were enrolled. We defined patients with an ejection fraction (EF) of ≥ 50% as HFpEF. Patients with severe valvular disease were excluded; the remaining 379 patients (women: n = 201, men: n = 178) were assessed. Women were older than men [median: 85 (79–89) years vs. 83 (75–87) years, p = 0.013]. Diabetes mellitus, hyperuricemia, and coronary artery disease were more prevalent in men than in women (34.8% vs. 23.9%, p = 0.019, 23.6% vs. 11.4%, p = 0.002, and 23.0% vs. 11.9%, p = 0.005, respectively). EF was not significantly different between women and men. The cumulative incidence of cardiovascular death or hospitalization for congestive heart failure (CHF) was significantly lower in women than in men (log-rank p = 0.040). Women with HFpEF were older and less often exhibited an ischemic etiology; further, they were associated with a lower risk for cardiovascular death or hospitalization for CHF compared with men in the Japanese population.

Socio-economic status and 1 year mortality among patients hospitalized for heart failure in China

AIMS

This study explored the association between socio-economic status (SES) and mortality among patients hospitalized for heart failure (HF) in China.

METHODS AND RESULTS

We used data from the China Patient-centred Evaluative Assessment of Cardiac Events-Prospective Heart Failure Study (China PEACE 5p-HF Study), which enrolled patients hospitalized primarily for HF from 52 hospitals between 2016 and 2018. SES was measured using the income, employment status, educational attainment, and partner status. Individual socio-economic risk factor (SERF) scores were assigned based on the number of coexisting SERFs, including low income, unemployed status, low education, and unpartnered status. We assessed the effects of SES on 1 year all-cause mortality using Cox models. We used the Harrell c statistic to investigate whether SES added incremental prognostic information for mortality prediction. A total of 4725 patients were included in the analysis. The median (interquartile range) age was 67 (57-76) years; 37.6% were women. In risk-adjusted analyses, patients with low/middle income [low income: hazard ratio (HR) 1.61, 95% confidence interval (CI) 1.21-2.14; middle income: HR 1.32, 95% CI 1.00-1.74], unemployment status (HR 1.43, 95% CI 1.10-1.86), low education (HR 1.25, 95% CI 1.03-1.53), and unpartnered status (HR 1.22, 95% CI 1.03-1.46) had a higher risk of death than patients with high income, who were employed, who had a high education level, and who had a partner, respectively. Compared with the patients without SERFs, those with 1, 2, 3, and 4 SERFs had 1.52-, 2.01-, 2.45-, and 3.20-fold increased risk of death, respectively. The addition of SES to fully adjusted model improved the mortality prediction, with increments in c statistic of 0.01 (P < 0.01).

CONCLUSIONS

In a national Chinese cohort of patients hospitalized for HF, low income, unemployment status, low education, and unpartnered status were all associated with a higher risk of death 1 year following discharge. In addition, incorporating SES into a clinical-based model could better identify patients at risk for death. Tailored clinical interventions are needed to mitigate the excess risk experienced by those socio-economic deprived HF patients.

Prognostic factors associated with quality of life in heart failure patients considering the use of the generic EQ-5D-5L™ in primary care: new follow-up results of the observational RECODE-HF study

BACKGROUND

The implementation of care concepts fitting the needs of patients with chronic heart failure (HF) remains challenging. In this context, psycho-emotional well-being is not routinely assessed, and under-researched despite indications that it is of great relevance for, e.g., acceptance, adherence, and prognosis. The aim of this study was to observe clinical characteristics for their prognostic utility in HF patients, and to compare the patients' health-related quality of life (QoL) with German population norm values.

METHODS

The current post-hoc analysis was performed on data collected amongst participants of the RECODE-HF study who had fully answered the EQ-5D-5L™ items at both baseline and 12 months (n = 2354). The status in the patients' self-assessment items, EQ-5D visual analog scale (VAS) and EQ-5D index was categorized into worse/unchanged/improved. General linear mixed models (GLMM) with logit link were applied. Subgroups included 630 patients (26.8%) screened positive and 1724 patients (73.2%) screened negative for psychosocial distress (PSD).

RESULTS

The 12-months change in EQ-5D index, generally resulting from change in individual EQ-5D items, additionally associated not only with high NYHA class but sociodemographics (employment/living alone/GP practice years) (96.2% correctly classified in GLMM). The 12- months change in individual QoL aspects showed associations with age*NYHA, gender, body-mass index, and comorbidities dyslipidemia, myocardial infarction, asthma/chronic pulmonary disease. Important social roles were reflected in particular when HF patients lived alone or the doctor mentioned to the patient that the patient had HF. Patients with/without PSD differed in some sociodemographic and clinical parameters. However, no influence of PSD could be demonstrated in the 12-month follow-up of the EQ-5D-5L™. Nonetheless, comparison of the 12-months QoL with general German population norm values by age groups < 75 years and 75+ showed markedly health restrictions in HF patients in all EQ-5D-5L™ aspects.

CONCLUSION

Our analysis revealed different prognostic factors primarily associated with change of burden in different QoL aspects in HF patients. In GP practice it is important to consider in addition to the overall day-related VAS all the individual health-related QoL aspects to take a holistic view of the patient, as well as to pay particular attention to the interrelation of individual characteristics.

The multiple mediating effects of social connectedness and self-care confidence on the relationship between subjective social status and emotional well-being in patients with heart failure: a cross-sectional study

BACKGROUND

Previous studies have shown that subjective social status (SSS) was positively associated with well-being in various populations. However, little is known about the relationship considering the underlying mechanism in patients with heart failure (HF).

AIMS

The aim was to study the effects of social connectedness and self-care confidence on the relationship between SSS and well-being in patients with HF according to the Reserve Capacity Model.

METHODS AND RESULTS

We recruited 296 patients from a general hospital using convenience sampling. SSS, social connectedness, self-care confidence, and well-being were assessed using self-reported questionnaires. A multiple mediation model was examined using the PROCESS macro in SPSS.Higher levels of SSS (r = 0.18, P < 0.01), social connectedness (r = 0.21, P < 0.01), and self-care confidence (r = 0.20, P < 0.01) were positively correlated with better emotional well-being, but not with physical well-being. The multiple mediation analysis revealed that the relationship between SSS and emotional well-being was mediated by social connectedness (effect: 0.061, 95% CI [0.014, 0.148]) and self-care confidence (effect: 0.110, 95% CI [0.006, 0.249]) separately, and together in serial (effect: 0.008, 95% CI [0.001, 0.028]).

CONCLUSIONS

Social connectedness and self-care confidence are multiple mediators of the relationship between SSS and emotional well-being. Interventions targeting to strengthening social connectedness and self-care confidence may improve emotional well-being directly. In addition, emotional well-being may be improved by enhancing SSS indirectly in patients with HF.

Association between the health insurance status and clinical outcomes among patients with acute heart failure in Japan

The relationship between the socioeconomic status, including the health insurance status, and prognosis of heart failure (HF) has been recognized as an important concept for stratifying the risk in HF patients and is gaining increasing attention worldwide even in countries with a universal healthcare system. However, the impact of the Japanese health insurance status on outcomes among patients admitted for acute HF has not been fully clarified. We enrolled 771 patients admitted for acute HF between January 2018 and December 2019 and collected data on the in-hospital mortality, length of the hospital stay, and cardiac events, defined as cardiovascular death and readmission for HF within 1 year after discharge. Patients were divided into two groups according to their insurance status, i.e., public assistance (n = 87) vs. other insurance (n = 684). The public assistance group was significantly younger and had a higher rate of diabetes, smoking, ischemic and hypertensive heart disease, and low estimated glomerular filtration rate (all P < 0.05). Pharmacological/invasive heart failure therapy, in-hospital mortality, and the 90-day cardiac event rate after discharge did not differ between the groups. However, the public assistance group had a significantly higher 1-year cardiac event rate than the other insurance groups (P = 0.025). After adjusting for covariates, public assistance was independently associated with the 1-year cardiac event rate (HR: 2.15, 95% CI: 1.42-3.26, P < 0.001). Acute HF patients covered by public assistance received the same quality of medical care, including invasive therapy. As a result, no health disparities were found in terms of the in-hospital mortality and 90-day cardiac event rate, unlike overseas surveys. Nevertheless, HF patients with public assistance had a higher risk for the long-term prognosis than those with other insurance. Comprehensive HF management is required post-discharge.

Psychosocial Syndemics and Multimorbidity in Patients with Heart Failure †

Heart failure (HF) is a common cause of hospitalization and mortality in older adults. HF is almost always embedded within a larger pattern of multimorbidity, yet many studies exclude patients with complex psychiatric and medical comorbidities or cognitive impairment. This has left significant gaps in research on the problems and treatment of patients with HF. In addition, HF is only one of multiple challenges facing patients with multimorbidity, stressful socioeconomic circumstances, and psychosocial problems. The purpose of this study is to identify combinations of comorbidities and health disparities that may affect HF outcomes and require different mixtures of medical, psychological, and social services to address. The syndemics framework has yielded important insights into other disorders such as HIV/AIDS, but it has not been applied to the complex psychosocial problems of patients with HF. The multimorbidity framework is an alternative approach for investigating the effects of multiple comorbidities on health outcomes. The specific aims are: (1) to determine the coprevalence of psychiatric and medical comorbidities in patients with HF (n = 535); (2) to determine whether coprevalent comorbidities have synergistic effects on readmissions, mortality, self-care, and global health; (3) to identify vulnerable subpopulations of patients with HF who have high coprevalences of syndemic comorbidities; (4) to determine the extent to which syndemic comorbidities explain adverse HF outcomes in vulnerable subgroups of patients with HF; and (5) to determine the effects of multimorbidity on readmissions, mortality, self-care, and global health.

Socioeconomic Status and Outcomes in Heart Failure With Reduced Ejection Fraction From Asia

BACKGROUND

Little is known regarding the impact of socioeconomic factors on the use of evidence-based therapies and outcomes in patients with heart failure with reduced ejection fraction across Asia.

METHODS

We investigated the association of both patient-level (household income, education levels) and country-level (regional income level by World Bank classification, income disparity by Gini index) socioeconomic indicators on use of guideline-directed therapy and clinical outcomes (composite of 1-year mortality or HF hospitalization, quality of life) in the prospective multinational ASIAN-HF study (Asian Sudden Cardiac Death in Heart Failure).

RESULTS

Among 4540 patients (mean age: 60±13 years, 23% women) with heart failure with reduced ejection fraction, 39% lived in low-income regions; 34% in regions with high-income disparity (Gini ≥42.8%); 64.4% had low monthly household income (<US$1000); and 29.5% had no/only primary education. The largest disparity in treatment across regional income levels pertained to β-blocker and device therapies, with patients from low-income regions being less likely to receive these treatments compared with those from high-income regions and even greater disparity among patients with lower education status and lower household income within each regional income strata. Higher country- and patient-level socioeconomic indicators related to higher quality of life scores and lower risk of the primary composite outcome. Notably, we found a significant interaction between regional income level and both household income and education status (P_interaction <0.001 for both), where the association of low household income and low education status with poor outcomes was more pronounced in high-income compared with lower income regions.

CONCLUSIONS

These findings highlight the importance of socioeconomic determinants among patients with heart failure in Asia and suggest that attention should be paid to address disparities in access to care among the poor and less educated, including those from wealthy regions.

The Relationship Between Uncertainty in Illness and Quality of Life in Patients With Heart Failure: Multiple Mediating Effects of Perceived Stress and Coping Strategies

BACKGROUND

Previous investigators have demonstrated that uncertainty in illness is associated with quality of life (QoL) in patients with chronic illness. However, little is known about the mechanism underlying the relationship in patients with heart failure.

OBJECTIVE

The aim of this study was to examine the multiple mediating effects of perceived stress and coping strategies on the relationship between uncertainty in illness and QoL in patients with heart failure.

METHODS

We conducted a cross-sectional study in 302 patients with heart failure recruited at a general hospital in China from October 2016 to September 2017. Uncertainty in illness, perceived stress, coping strategies, and QoL were assessed using self-reported questionnaires. The multiple mediation model was tested using the PROCESS macro for SPSS.

RESULTS

Of the 302 patients, 51.7% had poor physical QoL and 45.7% had poor mental QoL (physical component summary or mental component summary score of <50 points). Uncertainty in illness had a significantly negative indirect effect on mental QoL through perceived stress and acceptance-resignation (indirect effect, -0.02; 95% confidence interval, -0.04 to -0.01). Uncertainty in illness also had a significantly negative indirect effect on mental QoL via perceived stress only (indirect effect, -0.18; 95% confidence interval, -0.26 to -0.09).

CONCLUSIONS

Poor QoL is prevalent in patients with heart failure. Perceived stress and acceptance-resignation are important mediating factors between uncertainty in illness and mental QoL in patients with heart failure. Interventions aimed at reducing perceived stress and acceptance-resignation coping may be beneficial for improving mental QoL in patients with heart failure.

Changing Spatiotemporal Trends in County-Level Heart Failure Death Rates in the United States, 1999 to 2018

Background

Amid recently rising heart failure (HF) death rates in the United States, we describe county‐level trends in HF mortality from 1999 to 2018 by racial/ethnic group and sex for ages 35 to 64 years and 65 years and older.

Methods and Results

Applying a hierarchical Bayesian model to National Vital Statistics data representing all US deaths, ages 35 years and older, we estimated annual age‐standardized county‐level HF death rates and percent change by age group, racial/ethnic group, and sex from 1999 through 2018. During 1999 to 2011, ~30% of counties experienced increasing HF death rates among adults ages 35 to 64 years. However, during 2011 to 2018, 86.9% (95% CI, 85.2–88.2) of counties experienced increasing mortality. Likewise, for ages 65 years and older, during 1999 to 2005 and 2005 to 2011, 27.8% (95% CI, 25.8–29.8) and 12.6% (95% CI, 11.2–13.9) of counties, respectively, experienced increasing mortality. However, during 2011 to 2018, most counties (67.4% [95% CI, 65.4–69.5]) experienced increasing mortality. These temporal patterns by age group held across racial/ethnic group and sex.

Conclusions

These results provide local context to previously documented recent national increases in HF death rates. Although county‐level declines were most common before 2011, some counties and demographic groups experienced increasing HF death rates during this period of national declines. However, recent county‐level increases were pervasive, occurring across counties, racial/ethnic group, and sex, particularly among ages 35 to 64 years. These spatiotemporal patterns highlight the need to identify and address underlying clinical risk factors and social determinants of health contributing to these increasing trends.

Living Alone and Gender Differences in Rehospitalization for Heart Failure After Discharge Among Acute Heart Failure Patients

Home treatment for heart failure (HF) is one of the most important problems in patients after discharge as a secondary preventive measure for rehospitalization for HF. However, there are no detailed studies on gender differences in sociopsychological factors such as living alone for HF rehospitalization among patients with acute HF (AHF).This prospective multicenter cohort study enrolled patients with AHF between April 2015 and August 2017. Patients of each gender with first AHF were divided into those living alone and those not living alone. The primary endpoint was defined as rehospitalization for HF after discharge. Cox proportional hazard analysis was performed to determine the association between living alone and the endpoint.Overall, 581 patients were included in this study during the 3-year follow-up. The proportion of rehospitalization for HF was significantly higher in patients living alone than in those not living alone among male patients. However, female patients showed no difference in endpoints between the two groups. The difference was independently maintained even after adjusting for differences in social backgrounds in male patients (adjusted hazard ratio (HR) 2.02; 95% confidence interval (CI), 1.07-3.70). In female patients, the HR for rehospitalization for HF showed no difference between the two groups (adjusted HR, 0.99; 95% CI, 0.56-1.69).In this study population, male patients living alone after first AHF discharge had a higher risk of rehospitalization for HF than those not living alone, but these differences were not observed in female patients.

Humanistic burden and economic impact of heart failure – a systematic review of the literature

Background: Heart failure (HF) is increasing in prevalence worldwide. This systematic review was conducted to inform understanding of its humanistic and economic burden. Methods: Electronic databases (Embase, MEDLINE®, and Cochrane Library) were searched in May 2017. Data were extracted from studies reporting health-related quality of life (HRQoL) in 200 patients or more (published 2007–2017), or costs and resource use in 100 patients or more (published 2012–2017). Relevant HRQoL studies were those that used the 12- or 36-item Short-Form Health Surveys, EuroQol Group 5-dimensions measure of health status, Minnesota Living with Heart Failure Questionnaire or Kansas City Cardiomyopathy Questionnaire. Results: In total, 124 studies were identified: 54 for HRQoL and 71 for costs and resource use (Europe: 25/15; North America: 24/50; rest of world/multinational: 5/6). Overall, individuals with HF reported worse HRQoL than the general population and patients with other chronic diseases. Some evidence identified supports a correlation between increasing disease severity and worse HRQoL. Patients with HF incurred higher costs and resource use than the general population and patients with other chronic conditions. Inpatient care and hospitalizations were identified as major cost drivers in HF. Conclusions: Our findings indicate that patients with HF experience worse HRQoL and incur higher costs than individuals without HF or patients with other chronic diseases. Early treatment of HF and careful disease management to slow progression and to limit the requirement for hospital admission are likely to reduce both the humanistic burden and economic impact of HF.

Association of household secondhand smoke exposure and mortality risk in patients with heart failure

Background

Secondhand smoke (SHS) exposure is a well-established cardiovascular risk factor, yet association between SHS and prognosis of heart failure remains uncertain.

Method

Data were obtained from the US National Health and Nutrition Examination Surveys III from 1988 to 1994. Currently nonsmoking adults with a self-reported history of heart failure were included. Household SHS exposure was assessed by questionnaire. Participants were followed up through December 31, 2011. Cox proportional-hazards models were used to assess the association of household SHS exposure and mortality risk. Potential confounding factors were adjusted.

Results

Of 572 currently nonsmoking patients with heart failure, 88 were exposed to household SHS while 484 were not. There were totally 475 deaths during follow-up. In univariate analysis, household SHS was not associated with mortality risk (hazard ratio [HR]: 0.98, 95% confidence interval [CI]: 0.76–1.26, p = 0.864). However, after adjustment for demographic variables, socioeconomic variables and medication, heart failure patients in exposed group had a 43% increase of mortality risk compared with those in unexposed group (HR: 1.43, 95% CI: 1.10–1.86, p = 0.007). Analysis with further adjustment for general health status and comorbidities yielded similar result (HR: 1.47, 95% CI: 1.13–1.92, p = 0.005).

Conclusion

Household SHS exposure was associated with increased mortality risk in heart failure patients.

Exercise-based cardiac rehabilitation for adults with heart failure

BACKGROUND

Chronic heart failure (HF) is a growing global health challenge. People with HF experience substantial burden that includes low exercise tolerance, poor health-related quality of life (HRQoL), increased risk of mortality and hospital admission, and high healthcare costs. The previous (2014) Cochrane systematic review reported that exercise-based cardiac rehabilitation (CR) compared to no exercise control shows improvement in HRQoL and hospital admission among people with HF, as well as possible reduction in mortality over the longer term, and that these reductions appear to be consistent across patient and programme characteristics. Limitations noted by the authors of this previous Cochrane Review include the following: (1) most trials were undertaken in patients with HF with reduced (< 45%) ejection fraction (HFrEF), and women, older people, and those with preserved (≥ 45%) ejection fraction HF (HFpEF) were under-represented; and (2) most trials were undertaken in the hospital/centre-based setting.

OBJECTIVES

To determine the effects of exercise-based cardiac rehabilitation on mortality, hospital admission, and health-related quality of life of people with heart failure.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and three other databases on 29 January 2018. We also checked the bibliographies of systematic reviews and two trial registers.

SELECTION CRITERIA

We included randomised controlled trials that compared exercise-based CR interventions with six months' or longer follow-up versus a no exercise control that could include usual medical care. The study population comprised adults (> 18 years) with evidence of HF - either HFrEF or HFpEF.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened all identified references and rejected those that were clearly ineligible for inclusion in the review. We obtained full papers of potentially relevant trials. Two review authors independently extracted data from the included trials, assessed their risk of bias, and performed GRADE analyses.

MAIN RESULTS

We included 44 trials (5783 participants with HF) with a median of six months' follow-up. For this latest update, we identified 11 new trials (N = 1040), in addition to the previously identified 33 trials. Although the evidence base includes predominantly patients with HFrEF with New York Heart Association classes II and III receiving centre-based exercise-based CR programmes, a growing body of studies include patients with HFpEF and are undertaken in a home-based setting. All included studies included a no formal exercise training intervention comparator. However, a wide range of comparators were seen across studies that included active intervention (i.e. education, psychological intervention) or usual medical care alone. The overall risk of bias of included trials was low or unclear, and we downgraded results using the GRADE tool for all but one outcome.Cardiac rehabilitation may make little or no difference in all-cause mortality over the short term (≤ one year of follow-up) (27 trials, 28 comparisons (2596 participants): intervention 67/1302 (5.1%) vs control 75/1294 (5.8%); risk ratio (RR) 0.89, 95% confidence interval (CI) 0.66 to 1.21; low-quality GRADE evidence) but may improve all-cause mortality in the long term (> 12 months follow up) (6 trials/comparisons (2845 participants): intervention 244/1418 (17.2%) vs control 280/1427 (19.6%) events): RR 0.88, 95% CI 0.75 to 1.02; high-quality evidence). Researchers provided no data on deaths due to HF. CR probably reduces overall hospital admissions in the short term (up to one year of follow-up) (21 trials, 21 comparisons (2182 participants): (intervention 180/1093 (16.5%) vs control 258/1089 (23.7%); RR 0.70, 95% CI 0.60 to 0.83; moderate-quality evidence, number needed to treat: 14) and may reduce HF-specific hospitalisation (14 trials, 15 comparisons (1114 participants): (intervention 40/562 (7.1%) vs control 61/552 (11.1%) RR 0.59, 95% CI 0.42 to 0.84; low-quality evidence, number needed to treat: 25). After CR, a clinically important improvement in short-term disease-specific health-related quality of life may be evident (Minnesota Living With Heart Failure questionnaire - 17 trials, 18 comparisons (1995 participants): mean difference (MD) -7.11 points, 95% CI -10.49 to -3.73; low-quality evidence). Pooling across all studies, regardless of the HRQoL measure used, shows there may be clinically important improvement with exercise (26 trials, 29 comparisons (3833 participants); standardised mean difference (SMD) -0.60, 95% CI -0.82 to -0.39; I² = 87%; Chi² = 215.03; low-quality evidence). ExCR effects appeared to be consistent different models of ExCR delivery: centre vs. home-based, exercise dose, exercise only vs. comprehensive programmes, and aerobic training alone vs aerobic plus resistance programmes.

AUTHORS' CONCLUSIONS

This updated Cochrane Review provides additional randomised evidence (11 trials) to support the conclusions of the previous version (2014) of this Cochane Review. Compared to no exercise control, CR appears to have no impact on mortality in the short term (< 12 months' follow-up). Low- to moderate-quality evidence shows that CR probably reduces the risk of all-cause hospital admissions and may reduce HF-specific hospital admissions in the short term (up to 12 months). CR may confer a clinically important improvement in health-related quality of life, although we remain uncertain about this because the evidence is of low quality. Future ExCR trials need to continue to consider the recruitment of traditionally less represented HF patient groups including older, female, and HFpEF patients, and alternative CR delivery settings including home- and using technology-based programmes.

Independent factors associated with the impact of gastroesophageal reflux disease on health-related quality of life

BACKGROUND

although a number of factors have been associated with a deterioration in quality of life in gastroesophageal reflux disease, it is not known which has an independent influence.

OBJECTIVE

to evaluate factors independently associated with the impact of gastroesophageal reflux disease on health-related quality of life.

METHODS

a post-hoc analysis of a prospective cohort of patients diagnosed with gastroesophageal reflux disease was performed. The patients completed validated questionnaires to evaluate health-related quality of life (SF 36), gastroesophageal reflux disease (GERQ) and psychological factors (STAI and SCL 90R).

RESULTS

the study included 98 patients. The univariate analysis showed that a deterioration in the physical component of the SF36 was significantly associated with female gender, educational level, age, weight loss, severity of typical symptoms, supraesophageal symptoms and monthly income. The mental component was significantly associated with alcohol consumption, epigastric pain and lower scores on the STAI and SCL90 questionnaires. The multivariate analysis showed an independent association between the physical component of the SF36 and educational level (β = 0.29; p < 0.01), severity of symptoms (β = -0.38; p < 0.001), body mass index (β = -0.30; p < 0.005), state anxiety (β = 0.28; p < 0.01), female gender (β = -0.23; p < 0.05) and dyspepsia (β = -0.21; p < 0.05). Associated variables within the mental component included state anxiety (β = -0.39; p < 0.01) and depression (β = -0.32; p < 0.05).

CONCLUSIONS

the principal factors independently associated with a deterioration in health-related quality of life in patients with gastroesophageal reflux disease included the severity of typical symptoms and the presence of dyspepsia. There is also an additional impact of body mass index and the psychological component.

Early readmission for heart failure: An avoidable or ineluctable debacle?

Early hospital readmission after an episode of Acute Decompensated Heart Failure (ADHF) is an emerging issue that is causing a relevant clinical and economic burden. Although there might be several reasons for early readmissions, in many cases these might be effectively prevented by a more adequate post-discharge management, including recommendations on lifestyle and rehabilitation programs. However, almost half of hospitalizations are unrelated to specific cardiac causes and thus increases the difficulty in analyzing risks prediction. Many episodes are related to social environment, poor familiar assistance and inadequate followup program. In addition, the national and insurance companies constantly quest for a reduction of costs that could lead to inappropriately shortened hospital stays. Therefore, the suitability of early re-hospitalization as a correct target for good medical practice is highly debated. Nevertheless, the post-discharge phase after episodes of ADHF remains poorly analyzed in clinical trials and specific investigations should be considered during the transition period from acute to chronic status. A validated program, which focuses on an appropriate risk algorithm including cardiac and extracardiac precipitating factors is lacking. This is a necessary and it should become one of the most important targets to aim for in HF management and strategy.

Comorbidities, Sociodemographic Factors, and Hospitalizations in Outpatients With Heart Failure and Preserved Ejection Fraction

Patients with heart failure and preserved ejection fraction (HFpEF) tend to be older and have a high co-morbidity burden. The impact of co-morbid conditions and sociodemographic risk factors on outcomes in these patients has not been quantified. We evaluated 445 consecutive outpatients with HFpEF, defined as established diagnosis of heart failure (HF) with left ventricular ejection fraction at presentation >40% and no previous left ventricular ejection fraction ≤40%. Patients with specific cardiomyopathies, congenital heart disease, primary right-sided disease, valvular disease, or previous advanced HF therapies were excluded. After 2 years, there were 44 deaths and 609 all-cause hospitalizations; of these, 260 (42.7%) were cardiovascular hospitalizations, including HF, and 173 (28.4%) were specifically for HF. The highest attributable risk for hospitalizations was associated with marital status (single, divorced, and widowed had higher hospitalization rates compared with married patients), hypoalbuminemia, diabetes, atrial fibrillation, and renal dysfunction. The proportion of hospitalizations potentially attributable to these factors was 66.6% (95% confidence interval [CI] 56.4 to 74.4) for all-cause hospitalizations, 76.9% (95% CI 65.2 to 84.6) for cardiovascular hospitalizations, and 83.0% (95% CI 70.3 to 90.3) for HF hospitalizations. For composite end points, the proportion was 46.9% (95% CI 34.0% to 57.3%) for death or all-cause hospitalization, 45.7% (95% CI 29.3% to 58.2%) for death or cardiovascular hospitalization, and 43.7% (95% CI 24.2% to 58.2%) for death or HF-related hospitalization. In conclusion, among outpatients with HFpEF, most hospitalizations could be attributed to co-morbidities and sociodemographic factors. Effects of HF therapies on hospitalizations and related end points may be difficult to demonstrate in these patients. Multidisciplinary approaches are more likely to impact hospitalizations in HFpEF.
