Use, patient selection and outcomes of P2Y12 receptor inhibitors in patients with STEMI based on contemporary European registries.

Aims To describe the effectiveness and safety of P2Y12 receptor inhibitors in patients with STEMI based on the data from contemporary European ACS registries.Methods and results Twelve registries provided data in a systematic manner on outcomes in STEMI patients overall, and seven of these also provided data for P2Y12 receptor inhibitor-based dual antiplatelet therapy. The registries were heterogeneous in terms of site, patient, and treatment selection, as well as in definition of endpoints (e.g. bleeding events). All-cause death rates based on the data from 84 299 patients (9612 patients on prasugrel, 11 492 on ticagrelor, and 27 824 on clopidogrel) ranged between 0.49 and 6.68% in-hospital, between 3.07 and 7.95% at 30 days (reported in 6 registries), between 8.15 and 9.13% at 180 days, and between 2.41 and 9.58% at 1 year (5 registries). Major bleeding rates were 0.09–3.55% in-hospital (8 registries), 0.09–1.65% at 30 days, and 1.96% at 1 year (only 1 registry). Fatal/life-threatening bleeding was rare occurring between 0.08 and 0.13% in-hospital (4 registries) and 1.96% at 1 year (1 registry)
