Description
Summary:Background: There are few data on the prognostic significance of the wall motion score index compared with left ventricle ejection fraction after an acute myocardial infarction. Our objective was to compare them after the hyperacute phase. Methods: Transthoracic echocardiograms were performed in 352 consecutive patients with myocardial infarction, after the first 48 hours of admission and before hospital discharge (median 56.3 hours (48.2–83.1)). We evaluated the ability of the wall motion score index and left ventricular ejection fraction to predict the combined endpoint (mortality and rehospitalization for heart failure) as a primary objective and the independent events of the combined endpoint as a secondary objective. Results: In 80.7% of patients, the wall motion score index was high despite having an ejection fraction >40%. No patient had an ejection fraction
