Abstract
The aim of this meta-analysis was to compare the benefit of "early" vs. "delayed" P2Y12 inhibition in patients undergoing percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI).We conducted a meta-analysis including seven randomised controlled trials (RCTs) which compared early vs. delayed P2Y12inhibition in STEMI patients scheduled for PCI, providing data on major adverse cardiac events (MACE), all-cause death, and major bleeding. The primary endpoint was MACE. Secondary endpoints included stent thrombosis and the use of GP IIb/IIIa inhibitors (GPI). All endpoints were analysed at the shortest follow-up available. A total of 9,648 patients were included ("early"=4,792, "delayed"=4,856). "Early" P2Y12 inhibition was associated with a significant reduction in MACE rate (OR 0.73, 95% CI: 0.61-0.88, p=0.0008), myocardial infarction (OR 0.71, 95% CI: 0.57-0.90, p=0.004), bail-out GPI use (OR 0.87, 95% CI: 0.75-1.00, p=0.04) and improved coronary reperfusion before PCI (OR for Thrombolysis In Myocardial Infarction [TIMI] flow grade 2-3=1.12, 95% CI: 1.00-1.26, p=0.04). Major bleeding was not increased (OR 0.87, 95% CI: 0.62-1.21, p=0.41).A strategy of early effective P2Y12 inhibition in PCI of STEMI appears to improve coronary reperfusion before PCI, and reduce MACE, MI and bail-out GPI use without increase of major bleeding.
