摘　　要：目的:分析尼可地尔对急性ST段抬高型心肌梗死(ST-segment elevation myocardial infarction,STEMI)患者Tp-Te间期、Tp-Te/QT及预后的影响。方法:选取2021年9月—2023年1月在潍坊市益都中心医院接受急诊介入治疗的STEMI患者160例,以数表法随机分成治疗组(尼可地尔治疗,80例)和对照组(常规药物治疗,80例);比较两组术前及术后48 h、1周、2周、4周的Tp-Te间期、Tp-Te/QT比值;随访6个月,比较两组主要不良心血管事件(major adverse cardiovascular events,MACE)发生率及全因死亡率,并根据有无MACE发生将患者分成MACE组和无MACE组,比较两组临床资料,分析STEMI预后危险因素。结果:治疗组与对照组Tp-Te间期、Tp-Te/QT比值在时间及组间上,差异有统计学意义(P<0.05);术前,两组Tp-Te间期、Tp-Te/QT比值比较差异无统计学意义(P>0.05);术后48 h、1周、2周、4周,治疗组Tp-Te间期、Tp-Te/QT比值均低于对照组(P<0.05);随访6个月,治疗组MACE共发生10例(12.50%),死亡7例(8.75%),低于对照组的22例(27.50%)和12例(15.00%)(P<0.05)。MACE组射血分数低于无MACE组,术前Tp-Te间期、术前Tp-Te/QT比值高于无MACE组(均P<0.05)。logistic回归分析显示:低射血分数、术前高Tp-Te间期、术前高Tp-Te/QT比值是STEMI预后危险因素(均P<0.05)。ROC分析显示:Tp-Te间期、Tp-Te/QT比值预测MACE的AUC为0.663、0.643,联合预测为0.693。结论:尼可地尔可显著缩短STEMI患者介入术后Tp-Te间期及Tp-Te/QT比值,减少不良心血管事件,改善患者预后。低射血分数、术前高Tp-Te间期、术前高Tp-Te/QT比值与急性STEMI患者术后MACE的发生相关密切,其中Tp-Te间期、Tp-Te/QT比值对STEMI的预后有重要的预警意义。Objective To analyze the effects of Nicorandil on Tp-Te interval,Tp-Te/QT and prognosis in patients with acute ST-segment elevation myocardial infarction(STEMI).Methods A total of 160 STEMI patients receiving emergency interventional treatment in Yidu Central Hospital of Weifang City from September 2021 to January 2023 were selected and randomly divided into treatment group(Nicorandil treatment,n=80)and control group(conventional drug treatment,n=80)by numerical table method.The Tp-Te interval and Tp-Te/QT ratio before and 48 hours,1 week,2 weeks and 4 weeks after operation were compared between the two groups.After 6 months of follow-up,the incidence of major adverse cardiovascular events(MACE)and all-cause mortality were compared between the two groups,and the patients were divided into MACE group and non-MACE group according to the occurrence of MACE.The clinical data of the two groups were compared,and the prognostic risk factors of STEMI were analyzed.Results Tp-Te interval and Tp-Te/QT ratio between treatment group and control group were significantly different(P<0.05).Before surgery,there was no significant difference in the Tp-Te interval and Tp-Te/QT ratio between the two groups(P>0.05).At 48 h,1 week,2 weeks and 4 weeks after operation,the Tp-Te interval and Tp-Te/QT ratio in the treatment group were lower than those in the control group,there were significantly different in two groups(P<0.05).After 6 months of follow-up,there were 10 cases(12.50%)of MACE and 7 cases(8.75%)of death in the treatment group,which were lower than 22 cases(27.50%)and 12 cases(15.00%)in the control group,there were significantly different in two groups(P<0.05).The ejection fraction of MACE group was lower than that of non-MACE group,and the preoperative Tp-Te interval and Tp-Te/QT ratio were higher than those of non-MACE group(P<0.05).logistic regression analysis showed that low ejection fraction,high preoperative Tp-Te interval and high preoperative Tp-Te/QT ratio were risk factors for STEMI prognosis(all P<0.05).ROC analysi
