Aim: An algorithm that uses clinical factors and CYP2C19 genotype to guide P2Y12 inhibitor selection in high-risk patients undergoing percutaneous coronary intervention was implemented at our institution. We sought to evaluate use of this algorithm and identify which factors influenced P2Y12 inhibitor selection.
Patients & Methods: This retrospective cohort study included 264 patients receiving percutaneous coronary intervention from July-December 2012.
