  1. Values are n (%), mean ± SD, or median with interquartile range
  2. LVEDD left ventricular end-diastolic dimension, LVEF left ventricular ejection fraction, FS fraction shortening, LAD left anterior descending coronary artery, LCX left circumflex coronary artery, RCA right coronary artery disease, ISR in-stent restenosis, LM disease left main coronary artery disease
