目的评价冠状动脉内支架术治疗不稳定型心绞痛的临床疗效。方法对40例不稳定心绞痛患者,均在常规药物治疗的基础上行冠状动脉介入治疗。根据心绞痛、心电图变化评价临床疗效。平均随访半年。结果术后即刻,血管残余狭窄均<20%,相关血流恢复TIMI2～3级,手术成功率为97.2%。36例未再发作心绞痛,4例心绞痛发作次数明显减少。心电图30例恢复正常,6例ST-T变化改善大于50%,4例ST-T无明显改善。随访期间,无急性心肌梗死或死亡发生。结论动脉介入术是治疗不稳定型心绞痛安全而有效的方法,临床应予以推广。
Objective To evaluate the clinical effect of coronary stenting in the treatment of unstable angina pectoris. Methods Forty patients with unstable angina pectoris underwent coronary intervention on the basis of routine medical treatment. According to angina, ECG changes in the evaluation of clinical efficacy. The average follow-up of six months. Results Immediately after operation, the residual vascular stenosis was less than 20%, and the related blood flow recovered to TIMI level 2-3. The successful rate of operation was 97.2%. 36 cases did not have recurrent angina pectoris, 4 cases of angina pectoris decreased significantly. Electrocardiogram 30 cases returned to normal, 6 cases of ST-T changes improved more than 50%, 4 cases of ST-T no significant improvement. During follow-up, no acute myocardial infarction or death occurred. Conclusions Arterial intervention is a safe and effective method for the treatment of unstable angina pectoris. Clinical application should be promoted.
