Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	late lumen loss in-lesion at 6 months	late lumen loss in-lesion at 6 months assessed by blinded QCA	6 months
Secondary	Procedural Success	< 30% final stenosis, TIMI III flow, no flow-limiting dissection, and the absence of in-hospital MACE	during hospital stay of index procedure
Secondary	MACE	cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization	6 and 12 months
Secondary	Individual clinical endpoints	stent thrombosis, cardiac death, target lesion myocardial infarction, clinically driven target lesion revascularization, binary restenosis (stenosis = 50% at follow-up angiography)	6 and 12 months
