目的分析经皮冠状动脉介入术(PCI)治疗无保护左主干病变的安全性与有效性。方法回顾性总结我院2007年9月—2010年9月53例经选择接受PCI治疗的冠心病无保护左主干病变患者临床资料、疗效、随访结果。结果无保护主干病变PCI成功率为100%,所有患者治疗后临床症状消失,52例(98.11%)患者完成9～12个月随访,随访期MACE发生率为9.43%,再发心绞痛发生率为7.55%、急性心肌梗死发生率为1.87%、靶血管重建发生率为5.66%,无心性死亡患者。结论对经过选择的无保护左主干病变患者进行PCI是安全有效的,预后较好。
Objective To analyze the safety and efficacy of percutaneous coronary intervention (PCI) in the treatment of unprotected left main disease. Methods The clinical data, curative effect and follow-up results of 53 patients with unprotected left main coronary artery disease who underwent PCI during September 2007 to September 2010 in our hospital were retrospectively reviewed. Results The success rate of PCI in unprotected trunk lesions was 100%. The clinical symptoms disappeared in all patients after treatment, and 52 (98.11%) patients completed 9-12 months follow-up. The incidence of MACE at follow-up was 9.43%. The incidence of recurrent angina was 7.55%, the incidence of acute myocardial infarction was 1.87%, the incidence of target vessel reconstruction was 5.66%, patients without cardiac death. Conclusions PCI is safe and effective for selected patients with unprotected left main disease and has a good prognosis.
