Outcome Measures
Primary Outcomes (1)
The primary end point of the study is composite of death, myocardial infarction and target lesion revascularization at one year after stent implantation
12 months
Secondary Outcomes (4)
Myocardial infarction rate
12 months
Need of target lesion revascularization (TLR), defined as any revascularization procedure involving the target lesion due to luminal re-narrowing in the presence of symptoms or objective signs of ischemia.
12 months
All cause death
12 months
Stent thrombosis
12 months

Interventions
due to randomization Cypher stent will be implanted
due to randomization Taxus stent will be implanted
due to randomization a rapamycin-eluting stent with biodegradable polymer will be implanted
Due to randomization one bare-metal stent will be implanted. The decision about the stent type will be up to the interventionalist
Eligibility Criteria
You may qualify if:
- Patients older than age 18 with ischemic symptoms or evidence of myocardial ischemia in the presence of ≥ 50% de novo stenosis located in CABG
- Written, informed consent by the patient or her/his legally-authorized representative for participation in the study.
- In women with childbearing potential a negative pregnancy test is mandatory
You may not qualify if:
- Cardiogenic shock
- Target lesion located in the native coronary vessels.
- In-stent restenosis of CABG
- Target lesion located at internal mammary artery graft or free arterial graft
- Malignancies or other comorbid conditions (for example severe liver, renal and pancreatic disease) with life expectancy less than 12 months or that may result in protocol non-compliance.
- Known allergy to the study medications: clopidogrel, rapamycin, paclitaxel, stainless steel.
- Inability to take clopidogrel for at least 6 months.
- Pregnancy (present, suspected or planned) or positive pregnancy test.
- Previous enrollment in this trial.
- Patient's inability to fully cooperate with the study protocol.
