Measure
Prasugrel
Patients will be randomly (1:1) assigned to receive FDA approved doses of either prasugrel (60 mg loading dose - 10 mg/day maintenance dose) or ticagrelor (180 mg loading dose - 90 mg b.i.d maintenance dose). Prasugrel: Maintenance dose will be maintained for 10±3 days.
Ticagrelor
Patients will be randomly (1:1) assigned to receive FDA approved doses of either prasugrel (60 mg loading dose - 10 mg/day maintenance dose) or ticagrelor (180 mg loading dose - 90 mg b.i.d maintenance dose). Ticagrelor: Maintenance dose will be maintained for 10±3 days.
