Background: Although intracoronary abciximab failed to improve prognosis compared with intravenous route in unselected ST-segment elevation myocardial infarction (STEMI) patients, little is known about the role of intracoronary abciximab in diabetic patients. Objectives: To evaluate the efficacy of intracoronary abciximab administration in diabetic patients with STEMI undergoing primary percutaneous coronary intervention (PCI). Methods: Reperfusional and clinical outcomes of intracoronary abciximab compared with intravenous bolus abciximab according to diabetic status were evaluated in a pooled analysis of five randomized trials including 3158 STEMI patients. The primary clinical endpoint of the study was the composite of death or reinfarction at 30-day follow-up. Results: Among 584 diabetic patients (18.5%), the composite of death or reinfarction was significantly reduced with intracoronary abciximab compared to intravenous abciximab (4.7% vs. 8.8%; rate ratio [RR], 0.50; 95% confidence intervals [CI], 0.26-0.99; p = 0.04), driven by numerically lower deaths (3.7% vs. 6.4%; RR, 0.56; 95% CI, 0.26-1.20; p = 0.13). Moreover, a significant reduction in definite or probable stent thrombosis was observed in patients receiving intracoronary abciximab (1% vs. 3.5%; RR, 0.27; 95% CI, 0.07-0.99; p = 0.04). Although formal tests for interaction were not significant, no clinical benefit was apparent in the cohort of STEMI patients without diabetes (n = 2574). Conclusions: In diabetic patients with STEMI undergoing primary PCI, intracoronary abciximab may improve clinical outcomes as compared with standard intravenous use. These findings require confirmation in a dedicated randomized trial.
