Reloading Prasugrel or Clopidogrel on High Platelet Reactivity Before Percutaneous Coronary Intervention

Summary

High platelet reactivity unit (PRU) after loading dose clopidogrel in patients undergoing percutaneous coronary intervention (PCI) is related to high risk of short and long term recurrent ischemic events including stent thrombosis. The investigators hypothesize that additional loading of prasugrel in patients with high PRU after clopidogrel loading would be superior to additional loading of clopidogrel in reducing platelet reactivity and thereby result in lower risk of short term recurrent ischemic events.
