Worsening Renal Function and Congestion in Patients with Acute Heart Failure: A Study with Bioelectrical Impedance Vector Analysis (BIVA) and Neutrophil Gelatinase-Associated Lipocalin (NGAL).

Background: Worsening renal function (WRF) is frequently observed in the setting of aggressive diuresis for the treatment of acute decompensated heart failure (ADHF) and is associated with poor outcomes in some studies.

Objective: We sought to assess the relationship of WRF and congestion at discharge with events (cardiac death or heart failure hospitalization).

Methods: Eighty patients with ADHF were studied.
