SAH: systemic arterial hypertension; DM: diabetes mellitus; CKD: chronic kidney disease; COPD: chronic obstructive pulmonary disease; HF: heart failure; FC: functional class; AMI: acute myocardial infarction; MRS: myocardial revascularization surgery; VR: valve replacement with mortality and rehospitalization. 25 However, some studies have shown that not only BMI but also other anthropometric variables should be used in the assessment of HF patients, for a better assessment of body compartments and central obesity. 24,26 BIA has been currently validated to estimate body composition and nutritional status in healthy individuals, and in several clinical conditions, including malnutrition and chronic diseases. 9 The validity of its use in HF patients has been questioned, since the method is known to be influenced by the amounts of body fluids, and to not be appropriate for situations of altered hydration of tissues. 12,25 Therefore, in our study, we used standardization criteria for BIA; only stable patients participated in the study, and those with altered hydration were excluded. 12 According to BF%measured by this method, 67.7% of men and 71.4% of women were identified as obese, corresponding to themajority (68.3%) of the study population. Central obesity indicators are positively correlated with the amount of visceral adipose tissue and cardiometabolic disorders. 25 Our subjects had excess central adiposity according to all indicators studies (WC, C-index and WHtR). Similar findings were
