Abstract

Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor (clopidogrel, prasugrel, or ticagrelor) is indicated after percutaneous coronary intervention (PCI) to reduce the risk of atherothrombotic events. Approximately 30% of the US population has a CYP2C19 no‐function allele that reduces the effectiveness of clopidogrel, but not prasugrel or ticagrelor, after PCI. We have shown improved outcomes with the integration of CYP2C19 genotyping into clinical care to guide the selection of prasugrel or ticagrelor in CYP2C19 no‐function allele carriers. However, the influence of patient‐specific demographic, clinical, and other genetic factors on outcomes with genotype‐guided DAPT has not been defined. In addition, the impact of genotype‐guided de‐escalation from prasugrel or ticagrelor to clopidogrel in patients without a CYP2C19 no‐function allele has not been investigated in a diverse, real‐world clinical setting. The Precision Antiplatelet Therapy after Percutaneous Coronary Intervention (Precision PCI) Registry is a multicenter US registry of patients who underwent PCI and clinical CYP2C19 testing. The registry is enrolling a diverse population, assessing atherothrombotic and bleeding events over 12 months, collecting DNA samples, and conducting platelet function testing in a subset of patients. The registry aims to define the influence of African ancestry and other patient‐specific factors on clinical outcomes with CYP2C19‐guided DAPT, evaluate the safety and effectiveness of CYP2C19‐guided DAPT de‐escalation following PCI in a real‐world setting, and identify additional genetic influences of clopidogrel response after PCI, with the ultimate goal of establishing optimal strategies for individualized antiplatelet therapy that improves outcomes in a diverse, real‐world population.
