Abstract | BACKGROUND: METHODS: In the Platelet IIb/IIIa Antagonist for the Reduction of Acute Coronary Syndrome Events in a Global Organization Network B ( PARAGON B) trial, patients with an acute coronary syndrome were randomized to receive the IIb/IIIa inhibitor lamifiban or a placebo. To rigorously explore the potential benefits of LWMH and GP IIb/IIIa inhibition, we analyzed the rates of ischemic complications and safety outcomes in PARAGON B. RESULTS: Approximately one fifth of the patients received LMWH (805 vs 4395 UFH). For the overall cohort, the incidence of death/ myocardial infarction (MI)/severe recurrent ischemia (SRI) was 12.2%, and this composite end point was numerically lowest in the lamifiban with LMWH group (10.2%). Similarly, the incidence of death/MI was 11.0% for the entire cohort and lowest in the lamifiban and LMWH group (9.0%). The lower event rate for patients taking LMWH in the lamifiban group was sustained at 6 months, with a lower revascularization rate (51.5% vs 42.8%) and a lower composite of death/MI (13.8% vs 11.9%). Bleeding was comparable in the 2 heparin groups (1.4% with UFH vs 0.9% with LMWH). The propensity adjusted odds ratio for 30-day revascularization was significantly lower with LMWH (odds ratio 0.67, 95% CI 0.57-0.79, P <.001). There were no significant differences in death/MI/SRI at 30 days (P =.465), death/MI at 30 days (P =.264), and stroke at 30 days with the type of heparin use (P =.201) after propensity risk adjustment. CONCLUSIONS: In the PARAGON B trial, use of LMWH in conjunction with a GP IIb/IIIa inhibitor was safe and associated with a lower revascularization rate. These findings support the rationale and promise for combining GP IIb/IIIa blockers and LMWH for future management of acute coronary syndrome.
