Study on the Protective Effect of Edaravone on Myocardial Ischemia Reperfusion Injury

By Hui Hou

Abstract

Objective: Discussion the role of edaravone as a free radical scavenger in protective effect of thrombolysis in acute myocardial ischemia reperfusion injury. Besides compared with the control group and analyze the possible mechanism which is widely used in clinical setting. Method: 80 patients hospitalized within year 2012−2013 with acute myocardial infarction (AMI) were treated with intravenous thrombolytic therapy, and were divided into treatment group (n = 41) and control group (n = 39). Edaravone injection 30 mg + 0.9% normal saline solution 100 mL with intravenous drip, BID for 14 days was given to the treatment group before and after thrombolytic treatment. Whereas, control group was treated with intravenous drip of placebo. Both groups were monitored by echocardiography and hemodynamic monitoring, and the myocardium was measured by echocardiography. Coronary artery CT was used to determine the degree of obstruction. Results: Compared with the control group, pain and reperfusion arrhythmia in treatment group was reduced. The area of myocardial wall movement disorder was significantly decreased (p < 0.05), the difference was statistically significant. CT result comparing treatment group and control group and show that rate of coronary recanalization increases 1.7 times (p < 0.01), the differences were statistically significant. Conclusion: For acute myocardial ischemia injection of edaravone before reperfusion and combine with pharmacological treatment can alleviate myocardial ischemia reperfusion injury, effectively scavenge oxygen free radicals and improve the ability of antioxidant. Both improve the thrombolytic treatment and protective effect for acute myocardial ischemia were significant. Hence, edaravone can is a kind of new milestone in the clinical cardiovascular drugs
