- Abstract
- Background: The long-term prognostic implication of platelet reactivity after percutaneous coronary intervention (PCI) is not clearly known. Objectives: The impacts of platelet reactivity from the PTRG-DES consortium were assessed. Methods: The primary endpoint was the major adverse cardiac and cerebrovascular events (MACCE) including all-cause death, myocardial infarction, stent thrombosis, or stroke. Key secondary endpoints were all-cause mortality, major bleeding, and net adverse clinical events (NACE), including MACCE and bleeding. Results: Between 2003 and 2018, a total of 11,714 patients were enrolled and grouped into tertiles according to P2Y12 reaction units (PRUs): high PRUs (≥253), intermediate PRUs (188-252), and low PRUs (<188). The Kaplan-Meier (KM) estimates of the primary outcome were significantly different across the groups; the high-PRU group showed the highest MACCE rate at 5 years (12.9%, 11.1%, and 7.0% in high-, intermediate-, and low-PRU groups, respectively; P < 0.001), as well as at 1 year (P < 0.001). The high-PRU group had the greatest KM estimates of all-cause death (8.2%, 5.9%, and 3.7%, respectively; P < 0.001) at 5 years without significant differences of major bleeding, and resultant of a higher KM estimates of NACE (15.7%, 13.6%, and 9.7%, respectively; P < 0.001). A PRU ≥252, the best cutoff value, was strongly related to MACCE (HR: 1.39; 95% CI: 1.11-1.74; P = 0.003) and all-cause death at 5 years after PCI (HR: 1.42; 95% CI: 1.04-1.94; P = 0.026). The optimal cutoff value of aspirin reaction units predicting the MACCE occurrence was ≥414 and was significantly associated with 5-year MACCE occurrence or all-cause death (P < 0.001). Conclusions: In this large-scale cohort, high PRU was significantly associated with occurrence of MACCE, all-death death, and NACE at 5 years, as well as 1 year after PCI.
