Body composition in patients with obesity-related heart failure with preserved ejection fraction: A comparison study.

ABSTRACT:

Background

Appendicular lean mass index is a major determinant of cardiorespiratory fitness in patients with obesity-related heart failure with preserved ejection fraction (HFpEF). Moreover, appendicular lean mass index can be used to diagnose sarcopenia and sarcopenic obesity in this population. We aimed to validate the ability of segmental single-frequency bioelectrical impedance analysis (SF-BIA) to assess body composition compared with dual-energy x-ray absorptiometry (DXA) in patients with HFpEF and obesity, with a focus on appendicular lean mass index for its critical role in diagnosing sarcopenia and sarcopenic obesity.

Methods

We analyzed 62 euvolemic patients from a heart failure outpatient clinic with persistent obesity-related HFpEF (83.8% women, 60.8 ± 2.8 years
