Venoarterial extracorporeal membrane oxygenation in acute myocardial infarction

<正>Introduction Mortality and complications associated with acute myocardial infarction （AMI） have gradually decreased in the era of reperfusion therapy.However,the outcomes are still poor for AMI patients with severe complications.[1] The quest for further improvement of the use of active mechanical circulatory support （MCS） devices is rapidly evolving.Venoarterial extracorporeal membrane oxygenation （VA-ECMO） is a form of heart-lung bypass that offers temporary mechanical support and simultaneous extracorporeal gas exchange,usually acting as a bridge to recovery.It has been widely used since 1972,after its introduction.Venoarterial extracorporeal membrane oxygenation provides cardiopulmonary support and is used to rescue patients with cardiopulmonary collapse.The use of VA-ECMO after AMI with severe complications is increasing.Recent studies have demonstrated a significant increase in survival using VA-ECMO in patients with AMI,and early VA-ECMO initiation yields better outcomes.This review article is aimed at evaluating the use of VA-ECMO in patients with AMI.[2]
