急诊冠状动脉内支架置入治疗不稳定性心绞痛

目的　探讨在不稳定性心绞痛病人症状未缓解状态下行急诊冠状动脉内支架置入的疗效及安全性。方法　对53例不稳定性心绞痛病人在心绞痛反复发作时即行冠状动脉造影，明确病变后行冠状动脉支架置入术。结果　53处病变置入56个支架，术中无严重并发症，34例心绞痛消失；9例有不典型胸痛，症状在1～2天内消失，无急诊冠状动脉搭桥及死亡。随访3个月～3年,6例冠脉造影证实再狭窄，5例行再次PTCA术后症状消失，1例行PTCA后仍有症状行冠状动脉旁路移植术(CABG)，无死亡病例。结论　冠状动脉内支架置入治疗急性冠状动脉综合征近期及远期效果较好，治疗成功率及安全性较高。

Treatment of Unstableangina with emergent coronary stenting installing

Objective To investigate the effect of the treatment on unstable angina with emergency coronary stent installing. Methods Having treated 53 patients suffering from unstable angina in recent 3 years. We treated the patients with angiography to illuminate the features of lesions and proceeded with PTCA stenting when the angina was not completely controlled. Results We implanted 56 stents in 53 lesions. 34 patients had no symptom of angina after the procedure, and 9 patients had untypical chest pain which disappeared in 1-2 days. There were no death patients and cases which needed emergent CABG. After follow-up in 3 months to 3 years, there are 6 patients who had restenosis confirmed by coronary angiography. Through another PTCA process 5 patients symptom disappeared. 1 patient needed CABG when he still had angina after PTCA. No death in follow-up period. Conclusion This is an effective and safe method to treat unstable angina according to short or long period results.
