冠心病经皮冠状动脉内成形术的临床应用

目的：观察心绞痛、心肌梗死经皮冠状动脉内成形术（PTCA）的安全性和有效性。方法：不稳定型心绞痛3例，急性心肌梗死2例。其中病变血管6支，回旋支远端狭窄1例，左前降支完全闭塞1例，左前降支近端狭窄3例（其中1例合并右冠状动脉中段狭窄）。分别行PTCA或PTCA加支架术。结果：PTCA成功4例，失败1例。PTCA后有3例发现内膜撕裂和血管壁塌陷，随即行支架植入。术前急性心肌梗死溶栓治疗临床试验（TIMI）血流0－1级，术后均恢复TIMI血流3级。术后随访1－3个月，患者均无心绞痛发作。结论：PTCA和支架植入，是冠状血管再通安全而有效的方法。

Clinical application of percutaneous transluminal coronary angioplasty in coronary heart disease

Objective:To evaluate the efficiency and safety of percutaneoustrasluminal coronary angiolasty(PTCA) in unstable angina and acute myocardial infarction(AMI).Methods:PTCA or PTCA with coronary artery stent(CS) were performed in all patients,in which 3 patients with unstable angina pectoris and 2 patients with AMI,vessel disease were left circumflex in 1 patient,left anterior descending artery total occlusion in 1 patient,left anterior descending stenosis in 3 patients,right coronary artery stenosis in 1 patient.Results:PTCA were successed in 4 patients(success rate 80%) and coronary stent were implanted in 3 patients.TIMI 0～1 flow was in all patients before PTCA and TIMI 3 flow was recovered after PTCA or PTCA+CS.With follow-up 1～3 months,there were no any angina attack in all patients.Conclusions:PTCA+CS is a safety and efficient therapeutic maneuver in coronary vessel reperfusion.It is profitable for patients with unstable angina and acute myocardial infarction.
