Abstract:
Objective:To investigate the effects of nicorandil combined with thrombus aspiration during percutaneous coronary intervention on reperfusion arrhythmia in patients with acute ST-elevation myocardial infarction.Methods:180 patients with acute ST-elevation myocardial infarction who received treatment in Yidu Central Hospital, Weifang Medical University, China between January 2019 and June 2020 were included in this study. They were randomly assigned to receive either nicorandil combined with thrombus aspiration during percutaneous coronary intervention (NPCI group, n = 90) or conventional PCI (PPCI group, n = 90). Myocardial perfusion (myocardial blush grade 3 blood flow) and the occurrence of reperfusion arrhythmia within 24 hours after treatment were compared between the NPCI and PPCI groups. Results:The incidence of myocardial blush grade 3 blood flow in the NPCI group was significantly higher than that in the PPCI group [84.44% (76/90) vs. 68.88% (62/90), χ2 = 6.01, P = 0.01]. There was no significant difference in the total incidence of reperfusion arrhythmia between NPCI and PPCI groups ( χ2 = 1.19, P = 0.27). The incidence of severe reperfusion arrhythmia in the NPCI group was significantly lower than that in the PPCI group [13.33% (12/90) vs. 27.77% (25/90), χ2 = 5.75, P = 0.02]. The influential factor of severe reperfusion arrhythmia was analyzed by logistic regression taking whether NPCI treatment was used as the variable ( OR = 0.40, 95% CI 0.18-0.89, P = 0.02). The other factors that affect severe reperfusion arrhythmia included age ( OR = 0.71, 95% CI 0.19-0.92, P = 0.04), time from onset to reperfusion of infarct related artery ( OR = 0.62, 95% CI 0.21-0.98, P = 0.02), dcuhistory of pre-infarct angina pectoris ( OR = 0.67, 95% CI 0.19-0.98, P = 0.03), admission blood glucose level ( OR = 1.96, 95% CI 1.05-5.78, P = 0.03), admission leukocyte count ( OR = 1.99, 95% CI 1.02-6.18, P = 0.03) and cardiac function ( OR = 1.71, 95% CI 1.06-6.91, P = 0.04). Conclusion:Nicorandil combined with thrombus aspiration during percutaneous coronary intervention for the treatment of acute ST-elevation myocardial infarction can not only improve myocardial perfusion, but also reduce the incidence of reperfusion arrhythmia. The combined therapy is superior to monotherapy, has certain clinical significance and is innovative.
