Primary Outcome Measures
NameTimeMethod
Target Vessel Failure2 years

defined as composite event of cardiac death, non-fatal myocardiac infarction, target vessel revascularization

Secondary Outcome Measures
NameTimeMethod
Cardiac death5 years
All-cause death5 years
Composite event of death or myocardial infarction5 years
Composite event of cardiac death or myocardial infarction5 years
Procedural success7 days

Defined as mean lesion diameter stenosis less than 30% and without the occurrence of in-hospital myocardial infarction (MI), target vessel revascularization (TVR), or death

Target Vessel revascularization5 years
Number of myocardial infarction events5 years

Q wave myocardial infarction or non Q wave myocardial infarction

Target Lesion revascularization5 years
Number of stent thrombosis events5 years

DEFINITE 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;

Number of stroke5 years
