Two hundred and sixty seven consecutive patients in whom GP IIb/IIIa antagonist therapy was initiated in the catheterization laboratory for PCI were analyzed. Abciximab-treated patients were more likely to be undergoing primary (p<0.001) and rescue (p=0.022) PCI and to have received fibrinolytic therapy (p=0.013) when compared to patients receiving tirofiban or eptifibatide. There were no significant differences between abciximab- and non abciximab-treated patients in either the primary PCI or non primary PCI groups in any of the studied endpoints. In patients undergoing primary PCI, abciximab-treated patients when compared with non abciximab-treated patients exhibited a trend toward an increase in hospital LOS (7.8+/-7.0 d vs 6.2+/-3.9, p=0.19) and in the frequency of hemorrhagic complications (22.1% vs 5.3%, p=0.11). In patients not receiving fibrinolytic therapy, abciximab-treated patients experienced a trend toward increased hemorrhagic complications following PCI when compared to non abciximab-treated patients (10.2% vs 6.0%, p=0.28). Complications distant from the vascular access site comprised 62.5% of hemorrhagic complications in the abciximab-treated group, but only 20% of the complications in the non-abciximab treated population (p<0.001). These data suggest no differences in acute outcomes between groups of patients receiving abciximab or other approved GP IIb/IIIa antagonists highlighting a potential significant cost saving. These data will require interpretation following the publication of comparative trials.
