BODY FAT PERCENTAGE EVALUATED BY A BIOELECTRICAL IMPEDANCE ANALYSIS PROVIDES PROGNOSTIC VALUE IN ACUTE HEART FAILURE, BEYOND ON THE “OBESITY PARADOX”

Background: Obesity is associated with incident heart failure, but it is paradoxically associated with better prognosis during acute heart failure(AHF). Currently, obesity is usually identified by body mass index(BMI). Bioelectrical impedance analysis is a noninvasive modality for evaluating the
