Role of Mechanical Circulatory Support in Acute MI Management.

Abstract

Cardiogenic shock complicating acute MI carries high mortality and morbidity in many cases. Mechanical circulatory support devices are often used in these cases, aimed at improving patient-centered outcomes, although there is a lack of large randomized clinical trial-based evidence for many of such devices. Various circulatory support devices are available with their associated risks and benefits. Ideal circulatory support device intends to unload the myocardium, halt the spiral of ischemia, provide support for revascularization, and/or allow time for myocardial recovery. In this review paper, the commonly used mechanical circulatory support devices available for use in acute myocardial infarction settings are discussed, and the pros and cons of these devices are examined, considering the contemporary data for each. While this is an evolving field, the authors believe this paper can be helpful to review the current status of the use of mechanical support devices in the setting of acute MI and highlight some of the unmet needs in this field.
