Echocardiographic Parameters Predict Short- and Long-Term Adverse Cardiovascular Events in Patients with Acute Myocardial Infarction.

Abstract

ObjectiveThis study aimed to find echocardiographic parameters that can predict short- and long-term adverse cardiovascular events in patients with AMI.MethodsA total of 126 patients with AMI admitted to our hospital from July to December 2012 were enrolled in this study. All patients underwent echocardiographic examination within 12 hours after admission and received regular follow-ups until December 2018. The primary endpoint was a composite of the major adverse cardiovascular events (MACEs).ResultsIn the first year of this study, a primary endpoint occurred in 35 patients and the predictor derived from the echocardiography of 1-year primary endpoint was LVEF<40% (OR: 9.000, 95% CI 3.242-24.987, p<0.0001) and the area under the curve (AUC) for the predictor was 0.676 (95% CI 0.561-0.790, p=0.002). For the total 5 years, 57 patients underwent primary endpoint. The results of the 5-year primary endpoint were: E/E’>15 (OR: 4.094, 95% CI 1.726–9.710, P=0.001), the wall motion score index was (WMSI)>1.5 (OR: 12.791, 95% CI 1.511–108.312, P=0.019), and the AUC was 0.691 (95% CI 0.595–0.787 P<0.0001).ConclusionLVEF is correlated with a short-term outcome (1-year), and WMSI and E/E’ can predict a long-term outcome (5-year) in patients with acute myocardial infarction.
