Risk stratification of outcomes after coronary artery bypass grafting in ischemic cardiomyopathy with symptomatic heart failure.

ABSTRACT:

Background

To identify the predictors of all-cause mortality and heart failure (HF) events in patients with ischemic cardiomyopathy (ICM) undergoing isolated coronary artery bypass (CABG) grafting who present with symptomatic HF, and to identify potential stratification variables for future regenerative therapy trials.

Methods

We retrospectively analyzed data from 90 patients with ICM, left ventricular ejection fraction of ≤ 40%, and New York Heart Association class ≥ II who underwent primary isolated CABG. Clinical characteristics, operative data, and long-term outcomes were assessed. The primary endpoints were all-cause mortality and incidence of HF events, defined as a composite of all-cause mortality and initial HF readmission. Prognostic factors were evaluated using Kap
