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.

Outcome Measures
Primary Outcomes (2)
P2Y12 Reaction Units (PRU) Using VerifyNow™ at 0.5 Hours After Loading Dose
PRU at 0.5 hours after a single oral loading dose of either ticagrelor 180 mg or clopidogrel 600 mg given at the time of the bivalirudin bolus
0.5 hours post loading dose
P2Y12 Reaction Units (PRU) Using VerifyNow™ at 1 Hour After Loading Dose
PRU at 1 hour after a single oral loading dose of either ticagrelor 180 mg or clopidogrel 600 mg given at the time of the bivalirudin bolus
1 hour post loading dose
Study Arms (2)
Ticagrelor
EXPERIMENTAL90 mg oral tablet
Clopidogrel
ACTIVE COMPARATOR300 mg oral tablet
Interventions
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.
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.

- Patients with known bleeding diathesis or coagulation disorder; history of intracranial bleed.
- Use of Intravenous (IV) heparin less than 2 hours before procedure.
