Predicting the Future Need of Walking Device or Assistance by Moderate to Vigorous Physical Activity: A 2-Year Prospective Study of Women Aged 75 Years and Above
Objective. To examine the association between daily moderate to vigorous physical activity (MVPA) and the change in mobility function among community-dwelling Japanese women aged 75 years and above. Methods. This prospective study included 330 older women aged 75 years and above who could walk without a walking device or assistance. MVPA and light-intensity physical activity (LPA) were assessed using an accelerometer for seven consecutive days. MVPA was defined as an activity with an intensity of >3 metabolic equivalents. The study outcome was a change in mobility function, defined as the need of walking device or assistance, during the two-year period. Results. The results of the logistic regression analysis showed that MVPA was inversely associated with a decline in mobility function after controlling for LPA and potential confounders (adjusted odds ratio (OR) = 0.93 per 1âmin/d, 95% confidence interval (CI) = 0.88â0.99; P = 0.017), whereas LPA was not when adjusted for MVPA and confounders (adjusted OR = 0.99 per 1âmin/d, 95% CI = 0.96â1.01; P = 0.245). The receiver operating characteristics analysis identified a 7.9âmin/d of MVPA as the cut-off value. Conclusions. The results of this study suggest the importance of promoting daily MVPA for preventing mobility limitation in older women aged 75 years and above
Prognostic effects of cardiac rehabilitation in heart failure patients classified according to physical frailty: A propensity scoreâmatched analysis of a nationwide prospective cohort study
Background: Research regarding cardiac rehabilitation (CR) in the prognosis of heart failure (HF) patients and frailty remains lacking. Here, the effects of CR on the 2-year prognosis of HF patients were examined according to their frailty status. Methods: This multicenter prospective cohort study enrolled patients hospitalized for HF. Patients who underwent â„1 session per 2 weeks of CR within 3 months after discharge were categorized in the CR group. Patients were divided in a non-frailty (â€8 points) and physical frailty group (â„9 points) based on their FLAGSHIP frailty score. The score is based on HF prognosis, with a higher score indicating worsened physical frailty. A propensity score-matched analysis was performed to compare survival rates between the two groups according to their physical frailty status. Endpoints included HF re-hospitalization and all-cause mortality during a 2-year follow-up period. Results: Of 2697 patients included in the analysis, 285 and 95 matched pairs were distributed in the non-frailty and physical frailty groups, respectively, after propensity-score matching. CR was associated with lower incidence of HF rehospitalization in both non-frailty (hazard ratio 0.65; 95% confidence interval 0.44â0.96; p = 0.032) and physical frailty (0.54; 0.32â0.90; p = 0.019) groups. CR was not associated with all-cause mortality in either group (log-rank test, p > 0.05). Conclusion: These findings suggest the effects of CR on reduced HF rehospitalization, regardless of physical frailty status
Living alone and gender differences in rehospitalization for heart failure after discharge among acute heart failure patients
Prognostic impact of nutrition measures in patients with heart failure varies with coexisting physical frailty
Abstract Aims Malnutrition is prevalent among patients with heart failure (HF); however, the effects of coexisting malnutrition and frailty on prognosis are unknown. This study examines the impact of malnutrition and frailty on the prognosis of patients with HF. Methods and results We examined 1617 patients with HF aged 65 years or older (age: 78.6 ± 7.4; 44% female) from a Japanese multicentre prospective cohort study. The nutritional status was evaluated using the Geriatric Nutritional Risk Index (GNRI), Controlling Nutritional Status (CONUT), and Mini Nutritional Assessment Short Form on discharge. Frailty was assessed using the criteria determined in a previous study on patients with HF. The prognostic impact of each nutrition measure on the risk of composite allâcause mortality and cardiac readmissions within 2 years of hospital discharge was assessed using KaplanâMeier survival curves and Cox proportional hazards model analysis for nonâfrail and frail groups. Over 2324.2 personâyears of followâup, 88 patients died and 448 patients experienced readmission due to HF. In the nonâfrail group, poor nutritional status assessed using the GNRI and CONUT was associated with an increased hazard ratio (HR) of composite outcomes in the crude model; however, adjustment for potential confounders diminished the association. In the frail group, all three nutritional indicators were associated with the cumulative incidence of the study outcome (logârank test, P < 0.05). In multivariate analysis, only the CONUT score was associated with an increased HR even after adjustment for confounders. Conclusions The CONUT score predicted a poor prognosis in HF patients with coexisting physical frailty, highlighting the potential clinical benefit of nutritional assessment based on biochemical data for further risk stratification
