Bioelectrical impedance analysis for evaluation of adverse cardiovascular events in patients with acute coronary syndromes: a prospective cohort study.

ABSTRACT:

Background

Bioelectrical impedance analysis (BIA) is a noninvasive method for assessing body fluid composition and may offer prognostic value in patients with acute coronary syndrome (ACS).

Materials

In this longitudinal cohort study, we enrolled 467 patients with ACS to investigate the association between BIA-derived parameters and 1-year major adverse cardiac events (MACE), including all-cause mortality, reinfarction, or heart failure (HF) requiring rehospitalization. BIA focused on measuring the electrodynamic properties of intracellular and extracellular fluids.

Results

Patients who developed MACE had significantly higher impedance (Z, calculated as the vector sum of resistance [R] and reactance [Xc]) compared to those without MACE. A Z value of 417.5 was identifi
