Feasibility and Implementation of <i>CYP2C19</i> Genotyping in Patients Using Antiplatelet Therapy

Abstract

AIM: A tailored antiplatelet strategy based on CYP2C19 genotype may reduce atherothrombotic and bleeding events. We describe our experience with CYP2C19 genotyping, using on-site TaqMan or Spartan genotyping or shipment to a central laboratory. METHODOLOGY: Data from two ongoing projects were used: Popular Risk Score project (non-urgent percutaneous coronary intervention patients) and the Popular Genetics study (ST-segment elevation myocardial infarction patients). For both projects, the time to genotyping result was calculated. RESULTS: In the Popular Risk Score project (n = 2556), median time from blood collection to genotyping result was 4:04 h. In the Popular Genetics study (n = 1038), median time from randomization to genotyping result was 2:24 h. CONCLUSION: CYP2C19 genotyping is feasible in everyday clinical practice, both in the acute and non-acute settings.
