摘要
目的评价支架植入术对不稳定型心绞痛（UAP）的治疗效果。方法对22例不稳定型心绞痛患者行经皮冠状动脉腔内成形术（PTCA）及支架植入术，同期20例住院的不稳定型心绞痛患者做对照组，观察两组患者1年内心绞痛、急性心肌梗死、死亡、再次住院的发生率及出院后患者左室功能。结果介入治疗组手术全部成功，未见与手术有关并发症，1年内无死亡、无急性心梗、无接受冠脉搭桥术（CABG）者，其左室射血分数较对照组明显改善（P〈0．01）；对照组1年内1例死亡、3例发生急性心梗、1例接受外科搭桥术。结论支架植入术是目前对不稳定型心绞痛的一种安全、有效的治疗手段。
Objective To evaluate the effect of coronary stent in treatment of unstable angina pectoris. Methods 42 patients suffering from unstable angina pectoris were divided into two groups. Patients in the intervention group were treated with pereutaneous transluminal coronary angioplasty （PTCA） and stent while only standard drug treatment was applied in the control group. The incidence of angina pectoris, myocardial infarction, death and rehospitalization as well as left ventricle function were ollowed up for 1 year. Results All the operation was successful without any complication. There were no case of death, myocardial infarction and CABG in intervention group. Besides, the left ventricle ejection fraction was enhanced significantly compared with control group （P 〈0.01 ）. However, in the control group, 1 patient died, 3 patients attacked by acute myocardial infarction and 1 patient underwent CABG. Conclusion Coronary stent is the safe and effective treatment for unstable angina pectoris in the present.
