This meta-analysis aims to identify factors that predict higher risk of mortality after VA-ECMO for AMI. Methods: We meta-analyzed mortality after VA-ECMO for CS complicating AMI and the effect of factors from systematically selected studies published after 2009. Results: 72 studies (10,276 patients) were included with a pooled mortality estimate of 58 %. With high confidence in estimates, failure to achieve TIMI III flow and left main culprit were identified as factors associated with higher mortality. With low-moderate confidence, older age, high BMI, renal dysfunction, increasing lactate, prothrombin activity < 50%, VA-ECMO implantation after revascularization, and non-shockable ventricular arrythmias were identified as factors associated with mortality. Conclusion: These results provide clinicians with a framework for selecting patients for VA-ECMO for CS complicating AMI.
