Infarct Size Following Treatment With Second‐ Versus Third‐Generation P2Y12 Antagonists in Patients With Multivessel Coronary Disease at ST‐Segment Elevation Myocardial Infarction in the CvLPRIT Study

摘要

BackgroundThird‐generation P2Y12 antagonists (prasugrel and ticagrelor) are recommended in guidelines on ST‐segment elevation myocardial infarction. Mechanisms translating their more potent antiplatelet activity into improved clinical outcomes versus the second‐generation P2Y12 antagonist clopidogrel are unclear. The aim of this post hoc analysis of the Complete Versus Lesion‐Only PRImary PCI Trial‐CMR (CvLPRIT‐CMR) substudy was to assess whether prasugrel and ticagrelor were associated with reduced infarct size compared with clopidogrel in patients undergoing primary percutaneous coronary intervention.
