Abstract Aims Sarcopenia, one of the extracardiac factors for reduced functional capacity and poor outcome in heart failure (HF), may act differently between HF with preserved ejection fraction (HFpEF) (HFrEF). We sought to investigate impact sarcopenia on mortality HFpEF HFrEF. Methods results performed a post hoc analysis multicentre prospective cohort study, including 942 consecutive older (age ≥65 years) hospitalized patients: 475 (ejection ≥45%, age 81 ± 7 years, 48.8% men) 467 HFrEF...

Abstract Background The purpose of this study was to clarify the prevalence, association with frailty and exercise capacity, prognostic implication sarcopenic obesity in patients heart failure. Methods present included 779 older adults hospitalized failure (median age: 81 years; 57.4% men). Sarcopenia diagnosed based on guidelines by Asian Working Group for Sarcopenia. Obesity defined as percentage body fat mass (FM) obtained bioelectrical impedance analysis. FM cut-off points were 38% women...

Background Frailty is conceptualized as an accumulation of deficits in multiple areas and strongly associated with the prognosis heart failure (HF). However, social domain frailty less well investigated. We prospectively evaluated clinical characteristics prognostic impact (SF) elderly patients HF. Methods Results FRAGILE-HF (prevalence value physical geriatric hospitalized for failure) a multicenter, prospective cohort study focusing on HF aged ≥65 years. defined SF by Makizako's 5 items,...

Although evidence suggests that cognitive decline and physical frailty in elderly patients with heart failure (HF) are associated prognosis, the impact of concurrent impairment, is, frailty, on prognosis has yet to be fully investigated. The current study sought investigate prevalence prognostic HF.This is a sub-analysis FRAGILE-HF, prospective multicentre observational involving aged ≥65 years hospitalized for HF. Fried criteria Mini-Cog were used diagnose respectively. association between...

Cachexia substantially impacts the prognosis of patients with heart failure (HF); however, there is no standard method for cachexia diagnosis. This study aimed to investigate association Evans's criteria, consisting multiple assessments, HF in older adults.This a secondary analysis data from FRAGILE-HF study, prospective multicentre cohort that enrolled consecutive hospitalized aged ≥65 years HF. Patients were divided into two groups: and non-cachexia groups. was defined according criteria...

ABSTRACT Background The Asian Working Group for Cachexia (AWGC) proposed a new definition of cachexia; however, its impact on cachexia prevalence and overlaps with other conditions, such as sarcopenia malnutrition, are unclear. We investigated these aspects the prognostic value based AWGC mortality in older patients heart failure (HF). Methods This study was secondary analysis prospective multicentre cohort, namely, FRAGILE‐HF cohort study. Older (≥ 65 years) who had been hospitalized due to...

Abstract Aims The benefits of exercise in patients with heart failure are well documented. However, to date, the association between habits and prognosis is yet be evaluated. In this study, we investigated pre-hospital post-discharge older adult failure. Methods This post-hoc analysis utilised data from FRAGILE-HF which included 1,262 aged ≥ 65 years who required hospitalisation for decompensation. Exercise before were assessed through a three-question physical activity assessment tool....

Abstract Frailty is a common comorbidity associated with adverse events in patients heart failure, and early recognition key to improving its management. We hypothesized that the AST ALT ratio (AAR) could be marker of frailty failure. Data from FRAGILE-HF study were analyzed. A total 1327 aged ≥ 65 years hospitalized failure categorized into three groups based on their AAR at discharge: low (AAR < 1.16, n = 434); middle (1.16 ≤ 1.70, 487); high 406). The primary endpoint was one-year...

Abstract Aims Functional decline due to skeletal muscle abnormalities leads poor outcomes in patients with acute heart failure (AHF). The 6-minute walking test (6MWT) reliably evaluates functional capacity, but its technical difficulty for the elderly often limits benefits. Although Short Physical Performance Battery (SPPB) is a comprehensive measure of physical performance, role AHF remains unclear. This study aimed examine prognostic significance SPPB compared 6MWT hospitalized AHF....

Abstract Aims Frailty is highly prevalent and associated with poor prognoses in elderly patients heart failure (HF). However, the potential effects of physical frailty on benefits HF medications are unclear. We aimed to determine influence prognosis reduced mildly ejection fraction (HFr/mrEF). Methods results From combined database FRAGILE‐HF Kitasato cohorts, hospitalized a left ventricular < 50% age ≥ 65 years were analysed. Patients treated or without renin‐angiotensin‐aldosterone...

Social factors encompass a broad spectrum of nonmedical factors, including objective (social isolation [SI]) and perceived (loneliness) conditions. Although social have attracted considerable research attention, information regarding their impact on patients with heart failure is scarce. We aimed to investigate the prognostic SI loneliness in older failure.
