†Lesion morphology assessed by operators. ‡Stent length calculated by operators. §Complex PCI is defined as having any of the following PCI characteristics: ≥3 vessels treated, ≥3 lesions treated, total stent length >60 mm, bifurcation with at least 2 stents implanted, atherectomy device use, left main PCI, surgical bypass graft or chronic total occlusion as target lesions. CABG: coronary artery bypass graft; CAD: coronary artery disease; LAD: left anterior descending; LCx: left circumflex; PCI: percutaneous coronary intervention; RCA: right coronary artery
