  1. SD = standard deviation, Min = minimum, Max: maximum, MMPOC = modified mechanical post-conditioning NYHA, New York Heart Association, LVEF = left ventricular ejection fraction, LMCA = left main coronary artery, Hb = hemoglobin, BUN: blood urea nitrogen, INR: international normalized ratio.
  2. Nominal variables were assessed by Chi square test or Fisher’s Exact test, where applicable. Continuous and ordinal variables were evaluated between two groups by Student’s t test and Mann–Whitney U test, respectively.
