Data are presented as n (%). Pearson chi-square test. Different lower case letters in a row indicate statistically significant difference between groups. CIN: contrast induced nephropathy, DHF: decompensated heart failure, MACE: major adverse cardiac events, RSS: residual SYNTAX score, and VT/VF: ventricular tachycardia/fibrillation.
