The impact of GP IIb/IIIa inhibitors during primary percutaneous coronary intervention in acute myocardial infarction patients.
The use of glycoprotein (GP) IIb/IIIa inhibitors during percutaneous coronary interventions (PCI) in the acute phase of myocardial infarction (AMI) is still a matter of debate. The aim of the present study was to compare the outcomes of patients with acute ST-segment elevation myocardial infarction who underwent primary PCI and were concomitantly treated with GP IIb/IIIa inhibitors with those who were not treated with these drugs. Between January 1996 and November 2003, a total of 418 consecutive patients underwent PCI in the setting of ST-segment elevation AMI. At the operator's discretion, 287 patients were concomitantly treated with GP IIb/IIIa inhibitors and 115 patients were not. Angiographic success and final TIMI 3 flow in the infarct-related artery was achieved more frequently in patients treated with GP IIb/IIIa inhibitors (90% vs. 77%; p=0.001). The in-hospital composite endpoint of death, reinfarction and bleeding complications was significantly better in patients treated with GP IIb/IIIa inhibitors (4% vs. 12%; p=0.005). Furthermore, the adjusted 12-month survival rate was significantly better in these patients (RR: 2.99, CI: 1.29-6.9; p=0.01). Therefore, adjunctive therapy with GP IIbIIIa inhibitors during primary PCI is associated with improved short-term outcomes and one-year survival without an increased risk of bleeding.
