Genotyping of cytochrome P450 CYP2C19 *2, *3 and *17 was performed and OPR was measured using the VerifyNow P2Y12 assay. Carriers were those with at least one CYP2C19 LOF allele.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>474 patients were enrolled; 236 received DAT, 238 TAT. Mean OPR was significantly lower in the TAT compared with the DAT group (207\u00b15 vs 236\u00b15, p&lt;0.001, P2Y12 reaction units, PRU). When grouped according to the presence of the CYP2C19 LOF allele, mean OPR was significantly lower in the TAT compared with the DAT group in only carriers of the LOF allele and not non-carriers (213\u00b16 vs 256\u00b17 PRU, p&lt;0.001 in carriers, 196\u00b19 vs 211\u00b18 PRU, p=0.242 in non-carriers for TAT vs DAT, respectively). The proportion of patients with high OPR was highest in carriers receiving DAT (60.8%) compared with the other three groups. On multivariate analysis, carriers on DAT was an independent predictor of high OPR (OR 2.93, 95% CI 1.64 to 5.21) along with female gender and increasing age.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>TAT significantly reduced OPR compared with DAT in carriers of the CYP2C19 LOF allele, but not in non-carriers.
