经皮腔内冠状动脉成形术治疗冠心病223例疗效观察

Percutaneous transluminal coronary angioplasty in 223 patients with coronary heart disease

目的:探讨经皮腔内冠状动脉成形术(PTCA)治疗冠状动脉粥样硬化性心脏病(冠心病)的疗效。方法:回顾分析应用PTCA治疗的223例冠心病患者,并记录住院和随访期间的心脏事件。结果:共扩张267支血管,左前降支126支,左回旋支47支,右冠状动脉94支。非完全闭塞性病变222支,成功率98.20%(218/222);完全闭塞性病变45支,成功率77.78%(35/45),明显低于非完全闭塞组(P<0.01)。50例患者因疗效不满意给予放置冠脉内支架57个,均获得满意的疗效。术后随访1～43个月,21例心绞痛复发,3例术后3个月发生心肌梗死。结论:PTCA是治疗冠心病的较为安全、有效的方法。

Objective:To assess the efficacy of percutaneous transluminal coronary angioplasty (PTCA) for patients with coronary artery disease. Methods: Two hundred and twenty three patients with coronary artery disease underwent PTCA using standard technique. Cardiac events during hospitalization and follow up were recorded. Results: The procedural success rate was 98.20% in the stenotic groups (218 of 222 blood vessels) and 77.78% in the total occlusion group (35 of 45 blood vessels). The successful rate of stenotic group was significantly higher than occlusive group ( P <0.01). Fifty seven stents were implanted in 50 patients for acute closure or significant residual stenosis during PTCA.During 1～43 month follw up, 21 cases had recurrence of angina and 3 cases had acute myocardial infarction during 3 months after PTCA. Conclusion: PTCA is safe and effective in patients with coronary artery disease with low incidence of major clinical complications.
