Background The impact of psychosocial states, such as depression or anxiety, and social support on the outcomes of stable outpatients with mild heart failure (HF) has not been evaluated in the "real world" clinical practice. Methods and ResultsIn the present study, 139 patients with a prior history of admission for HF provided the baseline demographic, clinical, socio-environmental, and psychosocial information. Cardiac death or re-admission because of worsening of HF was monitored during the follow-up period of 1 year. The prevalence of depression and anxiety were 37% and 37%, respectively, in HF patients. Depression was independently associated with male (sβ=-0.36, P=0.01), social ties (sβ=0.22, P=0.04) and low social support (sβ=-0.39, P<0.01). Anxiety was associated with alcohol drinking (sβ=0.22, P=0.04), brain natriuretic peptide ≥200 pg/dl (sβ=0.35, P<0.01), and low social support (sβ=-0.28, P=0.01). Kaplan-Meier analysis demonstrated that patients with anxiety (log-lank test; P<0.01) and lower scores of social support (P<0.01) had a higher rate of HF-related re-admission. Conclusions Anxiety and low social support were independently associated with HF-related re-admission, which indicates the need for their inclusion in the assessment and management of HF.

Background: Exercise-based cardiac rehabilitation (CR) improves health-related quality of life and exercise capacity in patients with heart failure (HF). However, CR efficacy in patients with HF who are elderly, frail, or have HF with preserved ejection fraction remains unclear. We examined whether participation in multidisciplinary outpatient CR is associated with long-term survival and rehospitalization in patients with HF, with subgroup analysis by age, sex, comorbidities, frailty, and HF with preserved ejection fraction. Methods: This multicenter retrospective cohort study was performed in patients hospitalized for acute HF at 15 hospitals in Japan, 2007 to 2016. The primary outcome (composite of all-cause mortality and HF rehospitalization after discharge) and secondary outcomes (all-cause mortality and HF rehospitalization) were analyzed in outpatient CR program participants versus nonparticipants. Results: Of the 3277 patients, 26% (862) participated in outpatient CR. After propensity matching for potential confounders, 1592 patients were included (n=796 pairs), of which 511 had composite outcomes (223 [14%] all-cause deaths and 392 [25%] HF rehospitalizations, median 2.4-year follow-up). Hazard ratios associated with CR participation were 0.77 (95% CI, 0.65–0.92) for composite outcome, 0.67 (95% CI, 0.51–0.87) for all-cause mortality, and 0.82 (95% CI, 0.67–0.99) for HF-related rehospitalization. CR participation was also associated with numerically lower rates of composite outcome in patients with HF with preserved ejection fraction or frail patients. Conclusions: Outpatient CR participation was associated with substantial prognostic benefit in a large HF cohort regardless of age, sex, comorbidities, frailty, and HF with preserved ejection fraction.

Background :Heart failure (HF), defined as a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood, is a leading cause of mortality and hospitalization for adults older than 65 years in the industrialized countries. The characteristics and outcome of patients with HF have been described by several epidemiological studies and large scale clinical trials, performed mainly in the United States and Europe. Very little information is available on this issue in Japan. Methods and Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) is designed to prospectively study the characteristics, treatment, and outcomes of a broad sample of patients hospitalized with HF at teaching hospitals throughout Japan between January 2004 to June 2005 and the outcomes, including death and hospital readmission, will be followed through 2006 (mean follow-up at least 1 year). Participating cardiologists identify patients admitted for worsening of HF symptoms. Demographics, medical history, severity, treatment, and outcome data are collected and entered into a database via secure web browser technology. As of June 2005, baseline data for 2,676 patients with HF have been registered from 164 participating hospitals. Conclusions: The JCARE-CARD will provide important insights into the management of patients with HF in routine clinical practice in Japan, thus providing the framework for improved management strategies for these patients.
