Usefulness of four echocardiographic risk assessments in predicting 30-day outcome in acute myocardial infarction.
One thousand fifty-one consecutive patients who had acute myocardial infarction were classified into 3 risk groups by 4 echocardiographic risk assessments: left ventricular ejection fraction, left ventricular filling pattern, estimated systolic pulmonary artery pressure, and mitral regurgitation, with 30-day mortality rates of 13.7%, 3.8%, and 1%, respectively (p <0.001). Independent echocardiographic and clinical predictors of 30-day mortality included age (10 years, hazard ratio [HR] 1.30, 95% confidence interval [CI] 0.91 to 1.89), female gender (HR 2.12, 95% CI 0.94 to 4.74), Killip's class > or =II on admission (HR 3.09, 95% CI 1.38 to 7.11), group 2 (moderate) risk (HR 2.89, 95% CI 1.07 to 8.56), and group 1 (high) risk (HR 8.16, 95% CI 2.95 to 25.23).
