ObjectivesThe aim of this study was to compare eptifibatide and abciximab as adjuncts to primary percutaneous coronary intervention (PCI).BackgroundThe glycoprotein (GP) IIb/IIIa receptor inhibitor abciximab as adjunct to primary PCI in patients with ST-segment elevation myocardial infarctions has been shown to reduce ischemic complications and improve clinical outcomes. So far, no trial has been performed to compare the efficacy of another GP IIb/IIIa receptor inhibitor, eptifibatide, and abciximab in primary PCI.MethodsA total of 427 patients with ST-segment elevation myocardial infarctions <12 h and planned primary PCI were randomized to double-bolus eptifibatide (n = 226) followed by a 24-h infusion or single-bolus abciximab (n = 201) followed by a 12-h infusion. In this noninferiority trial, the primary end point was the incidence of complete (> or =70%) ST-segment resolution (STR) 60 min after PCI, a measure of myocardial reperfusion. The assumption was a 60% complete STR rate in the abciximab group. The noninferiority margin was set to 15%.ResultsThe incidence of complete STR at 60 min after PCI in the intention-to-treat analysis was 62.6% after eptifibatide and 56.3% after abciximab (adjusted difference: 7.1%; 95% confidence interval: 2.7% to 17.0%). All-cause mortality 6.2% versus 4.5% (p = 0.50); reinfarction 0.4% versus 3.5% (p = 0.03); target vessel revascularization 4.4% versus 6.5% (p = 0.40); the combined end point of death, nonfatal reinfarction, and target vessel revascularization 10.6% versus 10.9% (p = 0.90); stroke 0.5% versus 0.5% (p = 1.00) after 6 months; and Thrombolysis In Myocardial Infarction major bleeding complications 4.0% versus 2.0% (p = 0.20) after 30 days were observed after eptifibatide and abciximab, respectively.ConclusionsEptifibatide as an adjunct to primary PCI is equally as effective as abciximab with respect to STR.
