Data are presented as mean ± SD, number (percentage). BMI was divided to BMI range (Group 1 ≤ 22 kg/m2, Group 2 ≥ 22 < 26 kg/m2 and Group 3 ≥ 26 kg/m2–Group 4 ≥ 26 < 30 kg/m2 Group 5 ≥ 30 kg/m2). P-value less than 0.005 is statistically significant.
Lesion based on American College of Cardiology/American Heart Association lesion classification. LAD left anterior descending artery, LCX left circumflex artery, LMCA left main coronary artery, TIMI thrombolysis in myocardial infarction.
