Body Composition and Survival in Patients With Heart Failure
Background
Body composition is increasingly recognized as an important factor in the prognosis of patients with heart failure (HF). Variations in muscle mass, fat-free mass, and fat mass may influence survival outcomes, but the extent of these associations remains unclear.
Objectives
This study aims to evaluate the impact of body composition parameters on survival in patients with HF.
Methods
Five databases were searched through January 2024. Eligible papers reported associations between body composition parameters and survival in HF patients. All-cause mortality was the primary outcome. Risk of bias was evaluated using the Newcastle-Ottawa scale. A random-effects model was used to calculate the 95% CI and HR, with heterogeneity assessed using Cochran’s Q and I2 tests.
Results
The analysis included 39 cohort studies involving 36,176 HF patients, with 21 studies included in the quantitative analysis. Low muscle mass (HR: 1.73 [95% CI: 1.32-2.26]; I2 = 47%) (7 studies) was significantly associated with increased all-cause mortality risk. The prognostic significance of low muscle mass remained consistent across sensitivity and subgroup analysis. Elevated fat mass was not associated with a risk of death (pooled adjusted HR: 0.75 [95% CI: 0.26-2.12]; I2 = 77%). Higher abdominal fat showed no significant mortality association.
Conclusions
The authors found a strong association between body composition parameters and all-cause mortality. Muscular wasting, measured by low muscle mass, was associated with increased mortality, strengthening the role of muscle mass in HF prognosis. In contrast, higher fat mass and abdominal adiposity showed no association. These findings underscore the importance of comprehensive body composition evaluation in HF prognosis.

期刊介绍:
JACC: Heart Failure publishes crucial findings on the pathophysiology, diagnosis, treatment, and care of heart failure patients. The goal is to enhance understanding through timely scientific communication on disease, clinical trials, outcomes, and therapeutic advances. The Journal fosters interdisciplinary connections with neuroscience, pulmonary medicine, nephrology, electrophysiology, and surgery related to heart failure. It also covers articles on pharmacogenetics, biomarkers, and metabolomics.
