目的探讨经皮冠脉腔内成形术(PTCA)及冠脉内支架术治疗不稳定心绞痛(UAP)的临床应用价值。方法对药物治疗疗效欠佳的不稳定心绞痛患者行冠脉造影术，单支血管病变行PTCA术并置入支架，双支或三支血管病变先判断“罪犯”病变血管，根据病情扩张包括“罪犯”病变血管在内的主要病变血管，可同期手术扩张双支血管或分期手术。结果 11例单支血管病变全部成功扩张后植入支架11枚，双支或三支血管病变中，3例患者首期仅扩张了“罪犯”血管，均接受了二期手术，5例患者同期手术扩张双支病变血管，5例患者仅扩张了“罪犯”血管，PTCA成功率为96.8%，置入支架30枚，成功率100%，术后血管前向血流全部TiMi3级。结论 PTCA及冠脉内支架术治疗UAP疗效确切，安全系数大，多支血管病变即使行不完全血运重建亦能显著缓解症状，减少病死率，提高生活质量，值得在基层医院推广。

Objective To evaluate the efficiency of percutaneous transluminalcoronary angioplasty（PTCA）and intracoronary stenting in treatment of unstable angina pectoris（UAP）．Methods Coronary angiography were performed in 24 patients with UAP．Results Eleven patients had one-vessel lesions，intracoronary stenting was implanted after PTCA，3 had two or three-vessel lesions，only dilate “culprit lesions”in first PTCA and other lesion was dilated in second PTCA after 2 weeks，5 patients only dilated “culprit lesions”．PTCA success rate was 96．8％，30 stenting were implanted and success rate was 100％．Conclusion PTCA and intracoronary stenting is a safe and effective therapy for the patients with UAP．
