Creatinine Clearance Measurement with Bioelectrical Impedance Analysis in Heart Failure Patients: Comparison with Estimated-Creatinine Clearance Formulas.

Background: Kidney disease is common in patients with heart failure (HF). The Donadio equation combines plasma creatinine and bioimpedance vector analysis (BIVA) to estimate creatinine clearance. This study aimed to compare the Donadio formula to the Cockcroft-Gault (CG), Modification of Diet in Renal Disease Study (MDRD-4), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations in patients with HF.

Respiratory failure and bioelectrical phase angle are independent predictors for long-term survival in acute heart failure.

The assessment of long-term mortality in acute decompensated heart failure (ADHF) is challenging. Respiratory failure and congestion play a fundamental role in risk stratification of ADHF patients. The aim of this study was to investigate the impact of arterial blood gases (ABG) and congestion on long-term mortality in patients with ADHF.

Congestion and nutrition as determinants of bioelectrical phase angle in heart failure.

Background: The whole-body bioelectrical phase-angle (PhA) is emerging as a new tool in stratifying prognosis in patients with both acute (AHF) and chronic heart failure (CHF).

Objective: To evaluate the determinants of PhA in HF patients.

Methods: We analyzed data from 900 patients with AHF or CHF (mean age: 76±10 years, 54% AHF).
