Over the years, several parameters obtained by cardiac imaging techniques have been proposed, to evaluate left ventricular remodeling (LVR) that occurs in patients who have experienced an acute myocardial infarction (STEMI) despite effective coronary revascularization and optimal medical therapy[1]. In addition to the parameters traditionally evaluated by conventional and three-dimensional echocardiography such as the end-diastolic and end-systolic volumes of LV (EDV, ESV) and the ejection fraction (EF) [2-3], interest has been placed at the global longitudinal tension (GLS)[4]and recently at the myocardial area size with severe longitudinal strain alteration (SAS) evaluated by two-dimensional echocardiography with speckle tracking (2D-STE) which has been shown to be correlated with the size of the transmural myocardial infarction[5]. This study aims to evaluate the value of the SAS area in predicting LVR after STEMI and also to compare it with other echocardiographic predictors and cardiac magnetic resonance imaging LVR (CMR) such as microvascular obstruction (MVO) and the global function index LV (LV-GFI).
