Variables with p < 0.05 in univariate analysis were entered into the multivariate model.
AMI, Acute myocardial infarction; BMI, Body mass index; EF, Ejection fraction; LA, Left atrium; LASr, Left atrial peak reservoir strain; LAVi, Left atrial volume index; LV, Left ventricle; LV–GLS, Left ventricular global longitudinal strain; LVMi, Left ventricular mass index. Numbers marked in bold are significant predictors of the outcome.
