Android to gynoid fat ratio and its association with functional capacity in male patients with heart failure

Abstract

Abstract Aims We studied the association between android (A) to gynoid (G) fat ratio and functional capacity (peak VO2) in male patients with heart failure with reduced ejection fraction (HFrEF). Methods and results We enrolled 118 male patients with HFrEF with left ventricular ejection fraction (LVEF) 25 kg/m2 with FNIH index 0.55 was detected in 60 patients. Relative peak VO2 was lower in patients with A/G ratio > 0.55 than in patients with A/G ratio 0.55 to be independently associated with reduced peak VO2 adjusted for age, body mass index, LVEF, presence of sarcopenia, anabolic hormones, and haemoglobin (odds ratio 3.895, 95% confidence interval 1.030–14.730, P = 0.045). Conclusions Body fat distribution, particularly android and gynoid fat composition, together with other cofactors, might have an important adverse role on functional capacity in male patients with HFrEF. Future studies are needed to address possible mechanisms involved in this relationship.
