Popis: | Objectives: The aim of this study was to compare efficacy and safety outcomes among patients receiving enoxaparin or unfractionated heparin (UFH) while undergoing percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI). Background: Primary PCI (pPCI) for ST elevation has traditionally been supported by UFH. The low molecular weight heparin enoxaparin may provide better outcomes when used for pPCI. Methods: Consecutive eligible patients (580) undergoing pPCI enrolled in the prospective electronic Pitie-Salpetriere registry of ischemic coronary syndromes (e-PARIS) registry were grouped according to whether they received UFH or enoxaparin as the sole anticoagulant. Logistic regression modeling, propensity-weighted adjustment, and sensitivity analyses were used to evaluate efficacy and safety endpoints for enoxaparin vs. UFH. Results: Enoxaparin was administered to 346 patients and UFH to 234 without ACT or anti-Xa guided dose adjustment. PCI was performed through the radial artery in 90%, with frequent (75%) use of GPIIb/IIIa antagonists. Patients receiving enoxaparin were more likely to be therapeutically anticoagulated during the procedure (68% vs. 50%, P < 0.0001) and were less likely to experience death or recurrent myocardial infarction (MI) in hospital (adjusted OR 0.28 95% CI (0.12–0.68) or by 30 days (adjusted OR 0.35 95% CI 0.16–0.81). All cause mortality was also reduced in hospital (adjusted OR 0.32, 95% CI (0.12–0.85) and to 30 days (adjusted OR 0.40 95% CI 0.17–0.99). Other ischemic endpoints were similarly reduced with enoxaparin. Thrombolysis in myocardial infarction (TIMI) major bleeding events were numerically fewer among patients receiving enoxaparin (1.2% vs. 2.6%, P = 0.2). Conclusions: In patients with STEMI presenting for PCI, enoxaparin was associated with a reduction in all ischemic complications, more frequent therapeutic anticoagulation, and no increase in major bleeding when compared against unfractionated heparin. © 2010 Wiley-Liss, Inc. |
