N2 - Objectives: We sought to evaluate the impact of GP IIb/IIIa receptor blockers on long-term mortality in patients undergoing PCI for AMI. Background: Glycoprotein (GP) IIb/IIIa inhibitors are potent suppressors of platelet aggregation and when used during percutaneous coronary intervention (PCI) for the treatment of acute myocardial infarction (AMI) may improve short-term clinical outcomes, including survival. However, the impact of GP IIb/IIIa treatment during PCI for AMI on long-term survival is unknown. Methods: Patients undergoing primary or rescue PCI for AMI within 24 hours of symptom onset with or without GP IIb/IIIa inhibitor treatment were identified from a multicenter PCI database. All cause mortality at a mean follow-up of 3 years was the primary end point. Results: Of the 269 patients treated with primary or rescue PCI for AMI, 107 (40%) received a GP IIb/IIIa antagonist. Patients treated with GP inhibitors were more likely to present with or develop heart failure (13% vs. 6.2%, P = 0.052). Left ventricular ejection fraction was reduced in those treated with GP IIb/IIIa antagonists (44% vs. 48%, P = 0.051). The extent of coronary artery disease did not differ between groups. Stent use was 80% in both groups. Procedural success was high and did not differ between groups. In-hospital mortality was low and did not differ between groups. The mortality at a mean follow-up of 3 years was 1.9% among patients treated with a GP IIb/IIIa antagonist and 15% for those who were not treated (log-rank P = 0.0005). Treatment with a GP IIb/IIIa antagonist was independently associated with a significant reduction in the hazard of long-term mortality (Hazard Ratio, 0.159; 95% Confidence Interval, 0.034-0.729; P = 0.018). Conclusions: Treatment of patients undergoing PCI for AMI with GP IIb/ IIIa antagonists appears to be associated with a profound reduction in late mortality.
