¹LGE transmural extent: 0 = 0%, 1 = 0%-25%, 2 = 25%-50%, 3 = 50%-75%, and 4 > 75%. LGE: Late gadolinium enhancement; ECG: Electrocardiography; LVEF: Left ventricular ejection fraction; STD: ST-segment depression; STE: ST-segment elevation; VT: Ventricular tachycardia; VF: Ventricular fibrillation; VPBs: Ventricular premature beats; MI: Myocardial infarction; ACEI: Angiotensin-converting enzyme inhibitor.
