N2 - Objectives: The authors sought to investigate the association between P2Y12 reaction units (PRU) and the risk of ischemic stroke (IS) after successful coronary drug-eluting stents (DES) implantation. Background: The association between platelet reactivity on clopidogrel and the risk for ischemic cerebrovascular events remains unclear. Methods: Incidence, predictors, and prognostic impact of IS were evaluated among patients enrolled in the multicenter, prospective ADAPT-DES (Assessment of Dual AntiPlatelet Therapy With Drug Eluting Stents) study. By protocol, patients were maintained on aspirin for 2 years and clopidogrel for at least 1 year. Baseline platelet reactivity on clopidogrel and aspirin were assessed by means of VerifyNow point-of-care assay after successful DES implantation. Results: Among 8,582 patients enrolled, 68 (0.8%) had an IS during 2-year follow-up. Across the spectrum of PRU, rates of IS were progressively greater as patients transitioned from the lowest quintile of PRU (more P2Y12 receptor inhibition; 2-year rate of 0.51%) to the highest quintile of PRU (less P2Y12 receptor inhibition; 2-year rate of 1.34%; adjusted p = 0.04). PRU >208 was independently associated with higher risk of IS at 2 years (adjusted hazard ratio 1.81; 95% confidence interval 1.08 to 3.04; p = 0.03). The association between higher PRU and risk for IS was also consistent in patients with versus without high CHA2DS2-VASc score (pinteraction = 0.30) and in those on or off oral anticoagulation at discharge (pinteraction = 0.99). Occurrence of IS was strongly associated with increased risk of all-cause mortality at 2 years (adjusted HR: 4.16; 95% CI: 1.95 to 8.87; p < 0.0001). Conclusions: Higher PRU was associated with increased risk of IS after coronary DES implantation. Ensuring adequate platelet P2Y12 receptor inhibition may reduce the risk of IS in this patient population.
