Peri-Procedural Myocardial Infarction, Platelet Reactivity, Thrombin Generation, and Clot Strength: Differential Effects of Eptifibatide + Bivalirudin Versus Bivalirudin

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.
