Glycoprotein IIb/IIIa inhibitors during rescue percutaneous coronary intervention in acute myocardial infarction.
Although percutaneous coronary intervention (PCI) following full-dose thrombolytic therapy (rescue angioplasty) is a common procedure, there is ample controversy regarding the usefulness of the procedure. Moreover, few data are available concerning the safety and efficacy of concomitant treatment with glycoprotein (GP) IIb/IIIa inhibitors in these patients. The aim of the present study was to compare the clinical outcomes of patients who underwent rescue PCI with stents and were treated with GP IIb/IIIa inhibitors. A total of 59 consecutive patients underwent rescue PCI at our institution during the study period, 29 patients (49.2%) were treated concomitantly with a GP IIb/IIIa inhibitor and 30 patients (50.8%) were not. Baseline clinical characteristics were similar between the two groups. In-hospital outcomes regarding death, reinfarction and the need for urgent target vessel revascularization was significantly lower in patients treated with GP IIb/IIIa inhibitors compared to those who were not treated (3.4% vs. 26.7%; p = 0.01, respectively). However, GP IIb/IIIa inhibitor administration was not an independent predictor of better outcomes by multivariate analysis. There was a higher rate of major bleeding complications in patients who received GP IIb/IIIa inhibitors, though it did not achieve statistical significance (6.9% vs. 0%; p = 0.14, respectively). The composite endpoint of major, minor bleeding and vascular complications was similar in both groups (24.1% vs. 16.7%; p = 0.48). In conclusion, the administration of GP IIb/IIIa inhibitors in patients undergoing rescue PCI after failed thrombolysis with stents was safe and may have a beneficial effect on 30-day event-free survival rates, without a significant increase in bleeding or vascular complications. These results warrant further investigation.
