Brief Summary:
Early reperfusion therapy has improved the clinical outcomes of patients with acute myocardial infarction (AMI), but these benefits are limited in some patients by reperfusion injuries. There is now increasing evidence that reactive oxygen species cause reperfusion injury. This study was designed to examine the effects of edaravone, a novel free radical scavenger, in patients with AMI.

Condition or disease Intervention/treatment Phase
Myocardial Infarction Reperfusion Injury Drug: edaravone Phase 4

Detailed Description:
Initial AMI patients were randomly assigned to receive 30 mg of edaravone or a placebo intravenously just before reperfusion. We compared infarct size, using serial determination of serum biomarkers and Q wave formations, and the incidence of reperfusion arrhythmia between the groups. Cardiovascular event-free curves were estimated by Kaplan-Meier method. In addition, we determined serum thioredoxin levels, an oxidative stress marker, to assess the antioxidant effect of edaravone.
