STEMI Treated With Primary Angioplasty and Intravenous Lovenox or Unfractionated Heparin (UFH)

Summary

Randomized evaluation of enoxaparin (0.5mg/kg IV) versus UFH (50-70IU/kg with GPIIb/IIIa inhibitors; 70-100IU without GPIIb/IIIa inhibitors). Anticoagulation can be continued after the procedure using the same agents as those allocated per randomization (enoxaparin SC, UHF IV or SC)
