冠状动脉内支架术治疗不稳定性心绞痛的疗效评价

目的:评价冠状动脉内支架术治疗不稳定性心绞痛的临床疗效.方法:不稳定性心绞痛病人38例,常规药物治疗的基础上行冠状动脉内支架术.根据心绞痛发作次数、心电图变化评价临床疗效.平均随访6个月.结果:术后即刻,血管残余狭窄均＜10%,相关血流恢复TIMI 2～3级,手术成功率为94.7%.36例未再发作心绞痛,2例心绞痛发作次数明显减少.心电图29例恢复正常,5例ST-T改变大于50%,4例ST-T无明显变化.随访期间,4例心绞痛复发,其中3例再次行冠状动脉内支架术,无急性心肌梗死或死亡发生.结论:冠状动脉内支架术是一种治疗不稳定性心绞痛的安全而有效的方法,值得临床推广.

The efficacy of coronary stenting in the treatment of patients with unstable angina

Objective:To evaluate the efficacy of coronary stenting in the treatment of patients with unstable angina.Methods:38 patients with unstable angina underwent coronary stenting based on routine conservative therapy.The clinical outcome was evaluated with regard to the frequency of angina and the changes in electrocardiogram.The patients were followed up for average 6 months.Results:The procedural success rate was 94.7% in the patients with residual stenosis less than 10% and initial TIMI grade 3 flow.There were no recurrent angina in 36 patients and significantly less angina frequency in 2 patients.The electrocardiogram in 29 patients recovered normally.More than 50% ST-T segment changes happened in 5 patients while 4 patients suffered no obvious changes.During the follow-up,4 patients presented recurrent angina,3 of which underwent repeat coronary stenting.There was no acute myocardial infarction or death.Conclusion:Coronary stenting is a safe and effective treatment for unstable angina.
