The investigators enrolled patients treated with DES during DAPT including clopidogrel who had at least one of VerifyNow test (PRU and ARU) and genotyping. In this consortium, the investigators tried to find the unique characteristics of East Asians based on platelet function, genotype and inflammatory markers.
The PTRG-DES consortium is a coalition composed of multi-center, real-world registries including CAD patients treated with DES in South Korea. From 9 academic registries in Korea, a total of 13,160 patients were enrolled for this database between July 2003 and August 2018. The aim of the study was to investigate long-term prognostic implications of platelet function and genotypes after DES implantation for significant CAD in South Korea.
