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).

Multiparametric approach to congestion for predicting long-term survival in heart failure.

Background: Congestion is a marker of adverse prognosis in patients with heart failure (HF). In addition to brain natriuretic peptide (BNP), estimated plasma volume status (ePVS), bioimpedance vector analysis (BIVA), and blood urea nitrogen/creatinine ratio (BUN/Cr) are emerging as new markers for congestion. The aim of this study was to evaluate the prognostic value of BNP, ePVS, BIVA, and BUN/Cr in HF.

Serum biochemical determinants of peripheral congestion assessed by bioimpedance vector analysis in acute heart failure.

Background: The pathophysiology of peripheral congestion is poorly investigated in patients with acute heart failure (AHF).

Objectives: to evaluate the relative contribution of serum colloid osmotic pressure (COP), relative plasma volume status (PVS), biomarkers of renal function, electrolytes, haemoglobin, and brain natriuretic peptide (BNP) in peripheral fluid overload using bioimpedance vector analysis (BIVA).

Methods: We retrospectively analysed data from 485 patients with AHF.

Supraventricular tachycardia, pregnancy, and water: A new insight in lifesaving treatment of rhythm disorders.

Pregnancy may predispose to paroxysmal supraventricular tachycardia (SVT), in subjects with or without identifiable heart disease. Many physiological conditions such as autonomic nervous system changes, altered systemic hemodynamics, etc. can contribute to the onset of arrhythmias during pregnancy.
