Abstract

Objectives: To assess the prognostic impact of the bioimpedance vector (bioelectrical impedance vector analysis [BIVA]) for patients hospitalized for heart failure (HF).

Material and methods: A prospective cohort of 105 patients hospitalized for HF. BIVA was performed prior to discharge, and the final sample was divided into 3 groups according to the value obtained: hyperhydration [hyperH] (>74.3%), normal hydration [normoH] (72.7-74.3%) and dehydration [desH] (<72.7%). In the follow-up, total mortality and readmissions for HF were considered adverse events.

Results: A higher incidence of events was observed among the patients with hyperH and desH compared with those with normoH (Kaplan-Meier: log-rank, 2.1; p=.04), with an increase in independent risk in the multivariate analysis (HR, 2.6 [1.05-6.44]; p=.039).

Conclusions: BIVA helps stratify the risk of readmission for HF and total mortality in the long-term follow-up of patients hospitalized for HF.
