Abstract
- Background: Diabetic patients are at increased risk for future cardiovascular events after ST-segment elevation myocardial infarction (STEMI). Administration of an intracoronary abciximab bolus during primary percutaneous coronary intervention (PCI) may be beneficial in this high-risk subgroup.<br />Objectives: This study sought to report the 1-year clinical outcomes and cardiac magnetic resonance (CMR) findings in STEMI patients with and without diabetes randomized to intracoronary or intravenous abciximab bolus at the time of primary PCI.<br />Methods: Patient-level data from 3 randomized trials were pooled. The primary endpoint was the composite of death or reinfarction. Comprehensive CMR imaging was performed in 1 study.<br />Results: Of 2,470 patients, 473 (19%) had diabetes and 1,997 (81%) did not. At 1 year, the primary endpoint was significantly reduced in diabetic patients randomized to intracoronary abciximab compared with those randomized to intravenous bolus (9.2% vs. 17.6%; hazard ratio [HR]: 0.49; 95% confidence interval [CI]: 0.28 to 0.83; p = 0.009). The intracoronary abciximab bolus did not reduce the primary endpoint in patients without diabetes (7.4% vs. 7.5%; HR: 0.95; 95% CI: 0.68 to 1.33; p = 0.77), resulting in a significant interaction (p = 0.034). Among diabetic patients, intracoronary versus intravenous abciximab bolus was associated with a significantly reduced risk of death (5.8% vs. 11.2%; HR: 0.51; 95% CI: 0.26 to 0.98; p = 0.043) and definite/probable stent thrombosis (1.3% vs. 4.8%; HR: 0.27; 95% CI: 0.08 to 0.98; p = 0.046). At CMR (n = 792), the myocardial salvage index was significantly increased only in diabetic patients randomized to intracoronary compared with intravenous abciximab (54.4; interquartile range: 35.1 to 78.2 vs. 39.0, interquartile range: 24.7 to 61.7; p = 0.011; p for interaction vs. no diabetes = 0.016).<br />Conclusions: In diabetic patients with STEMI, the administration of intracoronary abciximab improved the effectiveness of primary PCI compared with the intravenous bolus.<br /> (Copyright © 2016 American College of Cardiology Foundation.
