Data are presented as mean ± SD, median (0.250.75 percentiles), and n (%). ANOVA, Kruskal–Wallis test, and Pearson chi-square test were used and different letters show that there is a statistically significant difference. BMS: bare metal stent, CX: circumflex, DES: drug eluting stent, LAD: left anterior descending, LMCA: left main coronary artery, PCI: percutaneous coronary intervention, NA: not applicable, PostPro: postprocedural, PrePro: preprocedural, RCA: right coronary artery, RSS: residual SYNTAX score, SS: SYNTAX score, and TIMI: the thrombolysis in myocardial infarction.
