左冠状动脉主干明显狭窄,可引起大面积心肌缺血,该动脉闭塞则引起广泛前壁心肌梗死,威胁患者的生命。冠状动脉支架的进步,使经皮冠状动脉介入治疗(PCI)在左冠状动脉病变治疗中作用加大,学界研究已证实这项治疗的中期安全性和支架的有效性,应用药物洗脱支架更进一步增加了其有效 Left main coronary artery stenosis, can cause a large area of ​​myocardial ischemia, the artery occlusion is caused by anterior myocardial infarction, threatening the lives of patients. Advances in coronary stents have led to an increased role for percutaneous coronary intervention (PCI) in the treatment of left coronary artery lesions. Academic research has demonstrated the medium-term safety and scaffold efficacy of this treatment, and the use of drug-eluting stents Further increase its effectiveness
