The multivariable-adjusted Cox regression analysis accounted for age, sex, diabetes, and presence of cardiovascular disease at the start of the study as possible confounders (i.e., known coronary artery disease, coronary stent, prior ST-segment elevation myocardial infarction or non–ST-segment elevation myocardial infarction, prior stroke, ischemic cardiomyopathy). Note that only the significant data are presented. HR, hazard ratio; EF, ejection fraction; SL peak G, strain longitudinal peak global value; SL peak S, strain longitudinal peak systolic; SrL peak S, strain rate longitudinal peak systolic; SrL peak A, strain rate longitudinal diastolic peak A; SC peak G, strain circumferential global peak value; SC peak S, strain circumferential global peak systolic; SC peak P, strain circumferential peak positive; SrC peak E, strain rate circumferential diastolic peak E; SR peak G, strain radial peak global value; SrR peak E, strain rate radial diastolic peak E.
