Comparison of Antiplatelet Effect of Ticagrelor vs Tirofiban in Patients With Non-ST Elevation Acute Coronary Syndrome

Summary

This is a single-center, open-label prospective randomized pharmacodynamic investigation of two anti platelet regimens in patients who are planned to undergo PCI for non-ST segment elevation acute coronary syndrome(NSTE-ACS) for 24 hours 1. Ticagrelor : loading dose(180mg) followed by maintenance dose(90mg bid) 2. Tirofiban : 0.4ug/kg/min for 30min followed by 0.1ug/kg/min * both agents will be given on top of aspirin
