CMR, cardiovascular magnetic resonance; LVEDV, left ventricular end-diastolic volume; LVEF, left ventricular ejection fraction; LVESV, left ventricular end-systolic volume; MVO, microvascular obstruction; %AAR–salvaged, percentage of area at risk salvaged; %LV–AAR, percentage of left ventricular mass at risk; %LV–scar, percentage of left ventricular mass that is infarcted.
