Study of Optimal Clopidogrel Duration in Patients Receiving Drug Eluting Stents (SCORE Trial) (SCORE)
Study Overview
Detailed Description
SCORE is a multicenter, prospective randomized study of post-percutaneous coronary intervention (PCI) patients with an uneventful 1 year post-PCI course on dual anti-platelet therapy (DAPT) with clopidogrel and aspirin. Patient will be randomized to an additional 1 year of DAPT (treatment arm) vs. aspirin alone (control arm)to assess the following endpoints during the 1 year follow-up period:
- Death / Myocardial infarction (MI) (Primary end-point)
- Combined endpoints of death, myocardial infarction, repeat revascularization, stroke, and major/minor bleeding (Secondary end-point)
During the year of follow up, subjects will be contacted once every three months. This will enable us to track study endpoints in the study population. In addition the patients' medical records will be screened to investigate if any of the aforementioned endpoints have been reached.
