Background Intravenous nicorandil infusion with percutaneous coronary intervention (PCI) has been reported to reduce reperfusion injury events and improve cardiac function in patients with acute myocardial infarction (MI). However, there is limited information on the use of intracoronary nicorandil. Methods and Results In the present study, 73 patients with acute ST segment elevation MI undergoing PCI were randomly assigned to the Nicorandil Group (n=37) or the Control Group (n=36). The composite endpoints were the incidences of ventricular arrhythmia, no-reflow and slow flow. A significant difference in the composite endpoint was observed in the Nicorandil Group when compared with the Control Group (p=0.037). The occurrence of post Thrombolysis In Myocardial Infarction (TIMI) grade 3 was significantly higher in the Nicorandil Group (p=0.019). Major adverse cardiac events during hospitalization and within 30 days of treatment were similar between the 2 groups. Conclusion Administration of intracoronary nicorandil reduced the occurrence of no-reflow, slow reflow, and reperfusion arrhythmia, and improved the myocardial perfusion grade, TIMI flow during PCI and improved clinical outcomes in patients with acute MI.
