Objectives : We assessed the safety and efficacy of early administration of abciximab prior to percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI) patients. Background : Research suggests that platelet glycoprotein IIb/IIIa receptor inhibitors, e.g. abciximab, may improve myocardial perfusion. In particular, early administration in the emergency department, prior to PCI, may result in more effective reperfusion. Methods : Eighty AMI patients with planned PCI were randomized in a double‐blind fashion to receive a 0.25 mg/kg abciximab bolus either “early” in the emergency department or “late” in the catheterization laboratory after angiographic assessment. In total, 74 patients underwent PCI after diagnostic angiography, all of which then received an abciximab infusion of 0.125 μg/kg/min for 12 hr. Results : Prior to PCI, no significant differences were observed between the two groups regarding the angiographic endpoints or ST‐segment resolution. After PCI, thrombolysis in MI (TIMI) frame count (TFC) was significantly improved in patients treated early rather than in those treated late (23 ± 10 vs. 41 ± 35; P = 0.02). Consistent trends, also favoring early treatment, were observed for TIMI flow grade 3 (TFG 3), corrected TFC (CTFC), and TIMI myocardial perfusion grade 3 (TMPG 3). Nine deaths (4 early, 5 late) and six significant bleeds (4 early, 2 late) were observed at 30 days after randomization. Conclusions : Early administration of abciximab is both feasible and safe in patients planned for primary PCI, increasing coronary flow and myocardial reperfusion after PCI, as demonstrated by significantly decreased TFC scores and trends toward improvements in TFG, CTFC, and TMPG. © 2006 Wiley‐Liss, Inc.
