Brief Summary:
In the setting of reperfusion therapy in an acute myocardial infarction using primary percutaneous intervention (PCI), the body's own inflammatory system involving the complement cascade may be harmful. This study will test the safety and efficacy of a novel complement inhibitor, pexelizumab to reduce mortality at 30 days.
