0296: Heart failure diagnosis with bioelectrical impedance vector analysis in emergency department

Introduction The aim of this study was to evaluate bioimpedance vector analysis (BIVA) for the diagnosis of heart failure (HF) in patients with acute dyspnea in the emergency department (ED). Methods Patients with acute dyspnea presenting to the ED were prospectively enrolled. BIVA was measured with a multi-frequency impedancemeter. Four parameters were assessed: resistance (R), reactance (Ra), total body water (TBW), extracellular body water (EBW), Brain Natriuretic Peptide levels and cardiac ultrasound studies were performed in all patients on admission. Patients, were classified in HF and non-heart failure (NonHF) groups according to final diagnosis by expert cardiologists. Results 77 patients (39 males, age 68±14 years, weight 79,8±20,6 Kg) were included. Of the four BIVA parameters, Ra was significantly lower in the AHF group compared to non-AHF (32,7±14,3 versus 45,4±19,7; p Conclusion In a population of patients presenting with dyspnea, BIVA didn’t improve significantly the diagnostic performance for HF in addition to BNP alone also there significant levels of correlation.
