Background Abciximab is a widely used adjunctive therapy for acute coronary syndrome (ACS). However, the effect of intracoronary (IC) administration of abciximab on cardiovascular events remains unclear when compared with intravenous (IV) therapy. Methodology and Principal Findings We systematically searched the Medline, Embase, and Cochrane Central Register of Controlled Trials databases and reference lists of articles and proceedings of major meetings for obtaining relevant literature. All eligible trials included ACS patients who received either IC administration of abciximab or IV therapy. The primary outcome was major cardiovascular events, and secondary outcomes included total mortality, reinfarction, and any possible adverse events. Of 660 identified studies, we included 9 trials reporting data on 3916 ACS patients. Overall, IC administration of abciximab resulted in 45% reduction in relative risk for major cardiovascular events (RR; 95% confidence interval [CI], 24−60%), 41% reduction in RR for reinfarction (95% CI, 7−63%), and 44% reduction in RR for congestive heart failure relative to IV therapy (95% CI, 8−66%); however, compared to IV therapy, IC administration of abciximab had no effect on total mortality (RR, 0.69; 95% CI, 0.45−1.07). No other significant differences were identified between the effect of IC abciximab administration and IV therapy. Conclusions/Significance IC administration of abciximab can reduce the risk of major cardiovascular events, reinfarction, and congestive heart failure when compared with IV therapy.
