摘要 冠状动脉慢性完全闭塞(CTO)病变是指冠状动脉100%闭塞且闭塞超过3个月的病变。CTO病变行经皮冠状动脉介入治疗(PCI)技术难度大、即刻成功率低、术后再闭塞和再狭窄发生率高,故被认为是目前PCI领域最大的障碍和挑战。2014年欧洲心脏病学会(ESC)血运重建指南中将PCI改善CTO患者缺血症状作为Ⅱa类选择(证据级别B),可见CTO病变PCI选择仍有部分争议,笔者在此对CTO行PCI开通前后左心室功能改变的研究进展作一综述,并试图找寻其影响因素,为CTO治疗的选择提供依据。 （LI Bo-yan, QIU Chun-guang, LU Wen-jie, et al.） Abrtract： Coronary chronic total occlusions （CTO） are defined as an occluded coronary segment with thrombolysis in myocardial infarction flow 0 for ≥3 months duration. Percutaneous revascularization of CTO is difficult, with low immediate success rate, high incidence of reocclusion and restenosis, therefore, it is considered to be the largest obstacles and challenges in PCI field. 2014 European Society of Cardiology （ESC） guidelines has assigned a class Ⅱa （level of evidence B） recommendation for CTO PCI. In the current review, we focus on the impact of CTO revascularization on left ventricular ejection fraction, and search factors. Key Words：coronary artery, chronic total occlusions, percutaneous conronary intervention, left ventricular ejection fraction, development Department of Cardiology, the First Affiliated Hospital of Zhengzhou University, Zhengzhou 450052, China 参考文献：
