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.

Resumen
Objetivos

Evaluar el impacto pronóstico del análisis del vector de bioimpedancia (bioelectrical impedance vector analysis [BIVA]) en pacientes ingresados por insuficiencia cardiaca (IC).

Material y métodos

Cohorte prospectiva de 105 pacientes ingresados por IC. El BIVA se realizó previo al alta, y la muestra final se dividió en 3 grupos según el valor obtenido: hiperhidratación [hiperH] (>74,3%), normohidratación [normoH] (72,7-74,3%) y deshidratación [desH] (<72,7%). En el seguimiento, se consideraron eventos adversos la mortalidad total y los reingresos por IC.

Resultados

Se observó una mayor incidencia de eventos en los pacientes hiperH y desH respecto a los normoH (Kaplan-Meier: log rank 2,1; p=0,04), con un incremento de riesgo independiente en el análisis multivariado (HR 2,6 [1,05-6,44]; p=0,039).

Conclusiones

El análisis BIVA en pacientes ingresados por IC permite estratificar el riesgo de reingreso por IC y mortalidad total en el seguimiento a largo plazo.
