Conditions: Non-ST Elevation Acute Coronary Syndrome
Keywords: Percutaneous Coronary Intervention
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 34
Healthy volunteers: no

Brief summary:
The purpose of this study is to determine if ticagrelor is as effective as clopidogrel in rate of onset and degree of platelet inhibition for patients with non-ST elevation of acute coronary syndrome (NSTE-ACS) undergoing ad hoc percutaneous coronary intervention (PCI) with bivalirudin.

Detailed description:
Multi-center, open-label study that will compare the onset of the platelet inhibition with ticagrelor versus clopidogrel when administered with bivalirudin during PCI on a background therapy of aspirin in patients with NSTE-ACS.

Arms:
arm 1: 90 mg oral tablet arm 2: 300 mg oral tablet

Interventions: intervention 1: ticagrelor intervention 2: clopidogrel
Intervention descriptions: intervention 1: Single loading dose of 180mg of ticagrelor at time of bivalirudin administration. Beginning 12 hrs following study drug administration, all pts in the ticagrelor arm will receive ticagrelor 90 mg (maintenance dose) approximately every 12 hrs until Follow-up telephone contact. intervention 2: Single loading oral dose of 600 mg of clopidogrel will be given at time of bivalirudin administration. Beginning 4 hrs following study drug administration, all pts in the clopidorgrel arm will receive ticagrelor 180 mg for the loading dose, followed by 90 mg maintenance dose approximately every 12 hours until the Follow-up telephone contact.
