Insufficient data exists regarding the relationship between body mass index (BMI) and prognosis of chronic heart failure (CHF) specifically within low- middle-income Asian countries. The objective this study was to evaluate impact BMI on adverse outcomes ambulatory patients with CHF in Vietnam.Between 2018 2020, we prospectively enrolled consecutive outpatients clinically stable an observational cohort, single-center study. participants were stratified according Asian-specific thresholds. relationships (all-cause death all-cause hospitalization) analyzed by Kaplan-Meier survival curves Cox proportional-hazards model.Among 320 (age 63.5 ± 13.3 years, 57.9% male), median 21.4 kg/m2 (IQR 19.5-23.6), 10.9% underweight (BMI <18.50 kg/m2). Over a follow-up time 32 months, cumulative incidence mortality hospitalization 5.6% 19.1%, respectively. After multivariable adjustment, had significantly higher risk than normal (adjusted hazard ratios = 3.03 [95% CI: 1.07-8.55]). Lower remained associated worse when as continuous variable 1.27 1.03-1.55] per 1 decrease for mortality). However, not found be (p > 0.05).In Vietnam, lower BMI, especially status < 18.5 kg/m2), mortality. These findings suggest that should considered use classification, managed team consisting cardiologists, nutritionists, geriatricians.
