About this trial

This is an interventional treatment trial for Coronary Artery Disease focused on measuring dual antiplatelet therapy, sirolimus drug-eluting stent, major adverse cardiac events, bleeding

Eligibility Criteria

    5. Study Description

    Brief Summary
    The study aims to assess the effectiveness of dual antiplatelet therapy, aspirin alone versus steeply discontinued clopidogrel plus aspirin in preventing clinical MACE events.Our subject is beyond a 12-month period patients receiving sirolimus drug-eluting stent implantation.
    Detailed Description
    It is not clear that dual antiplatelet therapy is better than aspirin beyond 12-months period patients receiving sirolimus drug-eluting stent implantation. If aspirin plus clopidogrel reduced MACE rates without increasing blood events, the investigators will evaluate risk-benefit ratio. The investigators will observe all cause mortality, nonfatal myocardial infarction, or clinical-driven target vessel revascularization TVR in a 1-year trial duration. In addition, strokes, stent thrombosis, cardiac re-hospitalizations, dialysis/hemofiltration, duration of hospitalization and bleeding events will be observed.
