摘　　要：目的分析冠状动脉支架治疗缺血性心肌病心力衰竭的效果及对心脏超声指标的影响。方法抽取2018年2月至2020年10月安阳市第三人民医院收治的缺血性心肌病心力衰竭患者94例,按随机数字表法分为观察组与对照组,每组47例。对照组采用常规药物治疗,观察组在对照组基础上采用冠状动脉支架治疗。对比两组疗效、不良心血管事件发生率,并比较两组治疗前后美国纽约心脏病协会(NYNA)分级、心脏超声指标[左心室舒张末期内径(LVEDD)、左室后壁舒张末期厚度(LVPWT)、左室射血分数(LVEF)]、X线心胸比和6 min步行距离(6MWD)水平。结果观察组总有效率(97.87%,46/47)高于对照组(82.98%,39/47),P<0.05。治疗后,观察组NYNA分级优于对照组(P<0.05)。治疗后,观察组LVEDD、LVPWT低于对照组,LVEF高于对照组(P<0.05)。治疗后,观察组X线心胸比低于对照组,6MWD大于对照组(P<0.05)。观察组不良心血管事件发生率(2.13%,1/47)与对照组(12.77%,6/47)比较差异未见统计学意义(P>0.05)。结论冠状动脉支架治疗缺血性心肌病心力衰竭患者的疗效确切,可改善其心脏超声指标和心功能,降低X线心胸比,提高运动耐受力,并能预防不良心血管事件的发生,预后效果良好。Objective To analyze the effect of coronary artery stent in the treatment of heart failure complicated by ischemic cardiomyopathy and its influence on echocardiographic index.Methods A total of 94 patients with heart failure complicated by ischemic cardiomyopathy treated in Anyang Third People’s Hospital from February 2018 to October 2020 were selected and divided into observation group and control group according to random number table method,with 47 cases in each group.The control group was treated with conventional drugs,and the observation group was treated by coronary artery stent based on the treatment of the control group.The efficacy and incidence of adverse cardiovascular events were compared between the two groups.The New York Heart Association(NYNA)classification,cardiac ultrasound indicators,including left ventricular end-diastolic diameter(LVEDD),left ventricular posterior wall end-diastolic thickness(LVPWT),left ventricular ejection fraction(LVEF),X-ray cardiothoracic ratio,and 6 min walking distance(6MWD)level before and after treatment were compared between the two groups.Results The total effective rate of observation group(97.87%,46/47)was higher than that of control group(82.98%,39/47),P<0.05.After treatment,the NYNA grade of observation group was better than that of control group(P<0.05).After treatment,LVEDD and LVPWT in observation group were lower than those in control group,while LVEF was higher than that in control group(P<0.05).After treatment,cardiothoracic X-ray in observation group was lower than that in control group,and 6MWD was longer than that in control group(P<0.05).There was no significant difference in the incidence of adverse cardiovascular events between the observation group(2.13%,1/47)and the control group(12.77%,6/47),P>0.05.Conclusions Coronary stent therapy for patients with heart failure complicated by ischemic cardiomyopathy has a definite curative effect,which can improve echocardiographic index and cardiac function,reduce X-ray cardiothoracic ratio,improve exercis
