Short-term efficacy observation of percutaneous transluminal coronary angioplasty on unstable angina pectoris

目的 了解经皮冠状动脉腔内成形术 (PTCA)治疗不稳定性心绞痛的短期疗效。方法 在C型臂X光机上开展PTCA及冠脉内支架置入术并予随访。结果 35例患者进行了PTCA术 ,2 9例患者随访 6～ 2 3月 ,2 2例无心绞痛发作。结论 在C臂型X光机上开展PTCA及冠脉内支架置入术治疗不稳定性心绞痛安全有效。

Objective To evaluate short term efficacy of percutaneous transluminal coronary angioplasty(PTCA)on unstable angina pectoris. Methods PTCA and stenting were operated with C type arm digital subtraction angiography system, the patients who underwent PTCA were followed up by direct interview. Results 35 patients were underwent successful PTCA, 29 cases of these patients were followed up, and in 22 cases of these patients no evidence of angina pectoris was observed during 6～23 months. Conclusion To treat unstable angina pectoris, It is safe and effective that PTCA and stenting were operated with C type arm digital subtraction angiography system.
