Data expressed as mean ± standard deviation. CMR = cardiovascular magnetic resonance, STEMI = ST-segment elevation myocardial infarction, LVEDM = Left ventricular end-diastolic mass, LVEDV = Left ventricular end-diastolic volume, LVESV = Left-ventricular end-systolic volume, LVEF = Left ventricular ejection fraction, PCI = percutaneous coronary intervention, IRA = infarct-related artery.
