Impact of renal failure and high-platelet reactivity on major cardiovascular ischemic events among patients with acute coronary syndrome receiving dual antiplatelet therapy with ticagrelor

No study has so far evaluated the impact of chronic kidney disease (CKD) on high-on treatment platelet reactivity (HRPR) with ticagrelor and their prognostic consequences, that were therefore the aim of the present study.Patients on dual antiplatelet therapy with ASA+ticagrelor (90mg/twice a day) after percutaneous coronary revascularization for ACS were scheduled for platelet function assessment 30-90 days post-discharge. The primary study endpoint was defined as the occurrence of major cardiovascular events (a composite of cardiovascular death, recurrent acute coronary syndrome (MI), target vessel revascularization) at the longest available follow-up.We included 396 patients, that were divided according to CKD (eGFR
