Left Ventricular Mechanical Circulatory Support Devices for Cardiogenic Shock After Myocardial Infarction.

Cardiogenic shock is the most common cause of mortality in patients with acute myocardial infarction (AMI). Historically, AMI complicated by cardiogenic shock was associated with in-hospital survival of only ~50%. Recent advances in mechanical circulatory support have allowed for improved survival rates compared with only conventional medical treatment. However, the management strategy for AMI-related cardiogenic shock remains largely empirical due to limited high-quality evidence-based studies. In this review, we provide an overview of the four types of left ventricular mechanical circulatory support currently available, review new guideline updates from the American College of Cardiology Foundation/American Heart Association and European Society of Cardiology, and discuss recent and ongoing studies and registries in cardiogenic shock following AMI.
