NCT00370045

Brief Summary

The purpose of this study is to compare levels of clot formation (platelet aggregation), markers of heart muscle damage, and inflammation in two groups undergoing percutaneous coronary stent implantation. The first group will be on a regimen of high-dose clopidogrel used in combination with bivalirudin plus eptifibatide, and the second group will be on a regimen of high-dose clopidogrel with bivalirudin alone. Clinical outcomes will be determined up to one year after enrollment.

Outcome Measures

Primary Outcomes (1)

  • Compare the antiplatelet effects of clopidogrel+bivalirudin vs. clopidogrel+bivalirudin+eptifibatide in patients undergoing elective percutaneous intervention

Secondary Outcomes (3)

  • Compare the release of myocardial necrosis and inflammatory markers

  • Measure platelet reactivity with conventional light transmittance aggregometry and thrombelastography

  • Assess in-hospital 30 day, and 1 year clinical outcomes.
