Design outcomes

Primary

MeasureTime frameDescription
Composite event1 yearThe number of events with the first occurrence of a composite event(death, non-fatal myocardial infarction, target vessel revascularization)

Secondary

MeasureTime frameDescription
Cardiac death5 years
Myocardial infarction5 years
Composite event of death or myocardial infarction5 years
Composite event of cardiac death or myocardial infarction5 years
All death5 years
Target lesion revascularization5 yearsDefined as any repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion. All TLRs should be classified prospectively as clinically indicated or not clinically indicated by the investigator prior to repeat angiography. An independent angiographic core laboratory should verify that the severity of percent diameter stenosis meets requirements for clinical indication and will overrule in cases where investigator reports are not in agreement. The target lesion is defined as the treated segment from 5 mm proximal to the stent and to 5 mm distal to the stent.
Stent thrombosis5 yearsDEFINITE stent thrombosis : acute coronary syndrome and angiographic or pathologic evidence of stent thrombosis; PROBABLE stent thrombosis : unexplained death within 30 days or target-vessel infarction without angiographic information Academic Research Consortium (ARC) stent thrombosis is reported as a cumulative value at different time points and within the different separate time points. Time 0 is the time point after the guide catheter has been removed. Acute stent thrombosis: 0-24 hours after stent implantation; Subacute stent thrombosis: \>24 hours to 30 days post; late stent thrombosis: \>30 days to 1 year post; Very late stent thrombosis: \>1 year post;
Stroke5 years
Procedural success3 daysDefined as mean lesion diameter stenosis ≤50% and without the occurrence of in-hospital myocardial infarction (MI), target vessel revascularization (TVR), or death
Target vessel revascularization5 yearsDefined as any repeat percutaneous intervention or surgical bypass of any segment of the target vessel. The target vessel is defined as the entire major coronary vessel proximal and distal to the target lesion, which includes upstream and downstream branches and the target lesion itself. Clinical-driven Clinically indicated angiography at follow-up shows a percent diameter stenosis ≥ 50% (core lab QCA assessment) and if one of the following occurs: (1) a positive history of recurrent angina pectoris, presumably related to the target vessel; (2) objective signs of ischemia at rest (ECG changes) of during exercise test (or equivalent), presumably related to the target vessel; (3) abnormal results of any invasive functional diagnostic test (eg, Doppler flow velocity reserve, fractional flow reserve). Ischemia-driven if one of followings of above-mentioned symptom (clinical-driven) or sign of ischemia or diameter stenosis ≥ 70 %
