This sub-analysis investigated the impact of the time to PCI from loading with oral P2Y12 inhibitors (clopidogrel or ticagrelor) on periprocedural myocardial necrosis.35 Patients undergoing elective PCI (N = 1809) were divided into quartiles (Q) as a function of the P2Y12 inhibitor loading time before PCI. This evidence concerns the gene P2RY12 and Myocardial necrosis.
