Is Extracorporeal Membrane Oxygenator a New Weapon to Improve Prognosis in Patients With Profound Cardiogenic Shock Undergoing Primary Percutaneous Coronary Intervention

Despite advancements in pharmacological therapy and refinement of the tools and technique of primary percutaneous coronary intervention (PCI) and coronary artery bypass surgery, patients with acute myocardial infarction (AMI) complicated by profound cardiogenic shock (CS) still have unacceptably high in-hospital mortality and unfavorable long-term outcome. Thus, there is an imminent need of a new and safe treatment modality in the management of AMI complicated by profound CS. Growing evidence suggests that extracorporeal membrane oxygenator (ECMO)-supported primary PCI is an effective therapeutic option for saving lives under such conditions. In this review, we describe and interpret the potential role of circulatory mechanical support by ECMO in the setting of AMI complicated by profound CS for improving clinical outcomes.
