Outcomes in patients with acute myocardial infarction (AMI) who received adjunctive therapy with glycoprotein (GP) IIb/IIIa-receptor inhibitors during percutaneous coronary intervention (PCI) were studied. Data from a national all-payer database for the period from January 2000 to July 2001 were analyzed to compare in-hospital mortality, complications, incremental costs, and length of stay between AMI patients who did and did not receive a GP IIb/IIIa-receptor inhibitor during PCI. Risk adjustment was performed by logistic regression to account for differences in patient and institutional characteristics. Complications were evaluated as a composite of cardiac, noncardiac, procedural, and nonprocedural complications. Incremental costs and length of stay were analyzed by least-squares regression. A total of 32,529 patients in 99 hospitals were included. Only abciximab had a significant benefit for risk-adjusted mortality (odds ratio [OR] = 0.74, 95% confidence interval [CI] = 0.59-0.92, p = 0.007) and shorter length of stay (0.21 day, 95% CI = 0.09-0.34 day, p = 0.0013) compared with the controls. Eptifibatide was associated with fewer complications (OR = 0.86, 95% CI = 0.75-0.98, p = 0.02), and tirofiban incurred the lowest incremental cost ($644, OR = $252-$1,036, p < 0.0001), but abciximab had the most favorable cost-effectiveness ratio ($14,515 per life-year gained). Information from a large database supported the use of GP IIb/IIIa-receptor inhibitors in patients with AMI undergoing PCI. Treatment with abciximab was associated with favorable differences in survival, cost-effectiveness, and length of stay compared to treatment without a GP IIb/IIIa-receptor inhibitor.
