    Abstract:
    The aim of this retrospective study was to assess whether intravenous nicorandil, a hybrid of NO and a KATP channel opener, in conjunction with percutaneous coronary intervention (PCI) improves the long-term prognosis in patients with acute myocardial infarction (AMI). Intravenous nicorandil has already been shown to improve the in-hospital prognosis of patients with anterior AMI. The study population consisted of 272 patients with a reperfused AMI who were admitted during a similar time interval, before (control; n=114) and after nicorandil treatment (n=158). In the nicorandil group, a 4 mg bolus injection was given, followed by 6 mg/h infusion for 24 h and then oral nicorandil at 15 mg/day for at least 1 month. In the patients with an anterior AMI, left ventricular (LV) function was better and the frequency of LV remodeling was lower after 3 months in the nicorandil group; however, in those with a non-anterior AMI, there were no differences in functional outcome and the frequency of LV remodeling between the 2 groups. The frequency of cardiac events was significantly lower in the nicorandil group, and the use of nicorandil was derived as a potential factor related to freedom from cardiac events (p<0.01, odds ratio = 0.27). Nicorandil treatment was associated with better myocardial perfusion and a better functional and clinical outcome than PCI alone, and this beneficial effect was maintained for a long time, particularly in patients with anterior AMI.
