LMWH in Primary PCI No randomized data (against UFH) Registry data ExTRACT-PCI data in STEMI FINESSE: largest experience in primary PCI

Objectives Primary –Evaluate the safety of enoxaparin 0.5mg/kg IV (+ 0.3mg/kg SC) vs. UFH 40U/kg (max 3000U) in Primary PCI with in lab abciximab –Compare the safety of LMWH to UFH in facilitated PCI with both abciximab and reteplase and with abciximab alone Secondary –Compare LMWH to UFH within similar treatment strategies with respect to efficacy

Objectives Primary PCI with in lab Abciximab R Abciximab Facilitated Primary PCI Reteplase/Abciximab Facilitated Primary PCI Heparin (40U/kg, 3000U max) “Main Study” Primary PCI with in lab Abciximab R Abciximab Facilitated Primary PCI Reteplase/Abciximab Facilitated Primary PCI With Enoxaparin (0.5 mg/kg IV, 0.3 mg/kg SC) “LMWH Substudy” Compare safety and efficacy between LMWH and UFH

Conclusions Compared with UFH and after adjustment for confounding variables, enoxaparin (0.5mg/kg IV + 0.3mg/kg SC) was associated with reductions of: –Major bleeding –Death –Death and complications of MI –All composite ischemic end-points Limitations of a non-randomized comparison  the ATOLL randomized study is underway
