植入式左心室辅助装置在缺血性心力衰竭患者中的应用与进展

Application status and development of left ventricular assist devices in ischemic heart failure patients

缺血性心力衰竭患者在国内心力衰竭患者中的占比超过一半,也是植入式左心室辅助装置的主要应用群体,然而缺血性心力衰竭患者的左心室辅助装置植入治疗面临诸如患者选择、冠状动脉病变、小左心室、二尖瓣关闭不全以及室壁瘤等问题。针对这些问题,国外仅有一些小样本量的回顾性研究,并且缺乏相应的归纳总结;国内则尚缺乏对这些问题的系统认识。因而本文针对这一困境,对植入式左心室辅助装置在缺血性心力衰竭患者中的应用与进展做一概述,旨在帮助临床医师对缺血性心力衰竭患者的左心室辅助装置植入治疗策略有一个全面而系统的认识,并在一些具体问题的处理上提供相应的参考。

In China,more than half of heart failure patients are ischemic heart failure patients.And a large proportion of left ventricular assist device implantation patients are also ischemic heart failure patients.However,left ventricular assist device implantation in ischemic heart failure patients is facing with problems such as patient screening,coronary artery disease,small left ventricle,mitral insufficiency,and ventricular aneurysm.There are only a few retrospective studies with small sample sizes abroad trying to provide solutions to these problems.While there is a lack of systematic understanding of this issue in China.Therefore,we provide an overview of the application and progress of left ventricular assist devices in ischemic heart failure patients,aiming to help clinicians have a comprehensive understanding of this issue and provide some guidance.
