Continuous variables are expressed as mean ± SD or median (confidence interval); discrete variables are expressed as n (%). Bold values indicate significant differences among groups.

AAR = area at risk; CMR = cardiac magnetic resonance; LGE = late gadolinium enhancement; LVEDV = left ventricular end-diastolic volume; LVEF = left ventricular ejection fraction; LVESV = left ventricular end-systolic volume; MACE = major adverse cardiac events; MH = myocardial hemorrhage; MSI = myocardial salvage index; MVO = microvascular obstruction; PASP = pulmonary artery systolic pressure; RVEDV = right ventricular end-diastolic volume; RVEF = right ventricular ejection fraction; TAPSE = tricuspid annular plane systolic excursion; TTE = transthoracic echocardiography.
