Genotype-Guided Therapy
Subjects with high bleeding risk (HBR) on dual antiplatelet therapy (DAPT) with clopidogrel and aspirin, that underwent successful percutaneous coronary intervention (PCI) were stratified by the CYP2C19 loss-of-function (LOF) allele within one week of DAPT initiation. In this group, subjects identified as CYP2C19\*2 or\*3 LOF allele carrier were given prasugrel or ticagrelor monotherapy.
Prasugrel: 60 mg bolus then 10 mg daily
Tricagrelor: 180 mg bolus then 90 mg twice daily

Conventional Therapy
Subjects with high bleeding risk (HBR) on dual antiplatelet therapy (DAPT) with clopidogrel and aspirin, that underwent successful percutaneous coronary intervention (PCI) were stratified by the CYP2C19 loss-of-function (LOF) allele within one week of DAPT initiation. In this group, subjects identified as CYp2C19\*2 or\*3 LOF allele non-carriers continued with clopidogrel monotherapy.
Clopidogrel: 75 mg/day
