Upstream P2Y12 Inhibitors and the CABG Quandary

Given the extensive role that platelet activation and aggregation play in the pathophysiology of acute coronary syndromes, it seems reasonable to administer a P2Y12 inhibitor as early as possible to minimize thrombus formation and progression of ischemia. Nonetheless, there remains considerable controversy surrounding the optimal timing of P2Y12 inhibitor administration in those undergoing percutaneous coronary intervention. In this blog, we’ll explore the data for and against early P2Y12 inhibitor administration in those presenting with non-ST-segment-elevation acute coronary syndromes and how coronary artery bypass graft surgery should, or should not, impact the decision for when to administer P2Y12 inhibitors.
