BACKGROUND Despite therapeutic advances, chronic heart failure (CHF)-related mortality and hospitalization is still unacceptably high. Evidence shows that muscular wasting, sarcopenia, cachexia are independent predictors of mortality and morbidity in CHF and are signs of protein metabolism disarrangement (PMD), which involve all body proteins including circulating one. We postulate that circulating human serum albumin (HSA) could be a marker of PMD and catabolic low-grade inflammation (LGI) in CHF patients. METHODS One hundred sixty-six stable CHF patients (73% males), with optimized therapy referred to cardiac rehabilitation, were retrospectively divided into three groups based on their HSA concentration: ≥3.5 g/dL (normal value), 3.2-3.49 g/dL (low value); ≤3.19 g/dL (severe value). Hematochemical analyses (including circulating proteins and inflammatory markers) and body mass composition (by Bioelectrical Impedance Vector Analysis) were collected and compared. Correlations and multivariate regression were performed. RESULTS Despite being overweight (BMI=27 kg/m2), 75% of patients had reduced HSA (
