Predictors and Long-Term Clinical Impact of Heart Failure With Improved Ejection Fraction After Acute Myocardial Infarction.

ABSTRACT:

Background

Little is known about the characteristics and long-term clinical outcomes of patients with heart failure with improved ejection fraction (HFimpEF) after acute myocardial infarction.

Methods and results

From a multicenter, consecutive cohort of patients with acute myocardial infarction undergoing percutaneous coronary intervention, patients with an initial echocardiogram with left ventricular ejection fraction ≤40% and at least 1 follow-up echocardiogram after 14 days and within 2 years of the initial event were considered for analyses. HFimpEF was defined as an initial left ventricular ejection fraction ≤40% and serial left ventricular ejection fraction >40% with an increase of ≥10% from baseline at follow-up. Independent factors predicting HFimpEF were identified
