Abstract: Despite advances in early reperfusion and a technologic renaissance in the space of Mechanical
Circulatory Support (MCS), Cardiogenic Shock (CS) remains the leading cause of in-hospital
mortality following Acute Myocardial Infarction (AMI). Given the challenges inherent to conducting
adequately powered randomized controlled trials in this time-sensitive, hemodynamically
complex, and highly lethal syndrome, treatment recommendations have been derived from AMI patients
without shock. In this review, we aimed to (1) examine the pathophysiology and the new classification
system for CS; (2) provide a comprehensive, evidence-based review for best practices for
interventional management of AMI-CS in the cardiac catheterization laboratory; and (3) highlight
the concept of how frailty and geriatric syndromes can be integrated into the decision process and
where medical futility lies in the spectrum of AMI-CS care. Management strategies in the cardiac
catheterization laboratory for CS include optimal vascular access, periprocedural antithrombotic
therapy, culprit lesion versus multi-vessel revascularization, selective utilization of hemodynamic
MCS tailored to individual shock hemometabolic profiles, and management of cardiac arrest. Efforts
to advance clinical evidence for patients with CS should be concentrated on (1) the coordination
of multi-center registries; (2) development of pragmatic clinical trials designed to evaluate innovative
therapies; (3) establishment of multidisciplinary care models that will inform quality care
and improve clinical outcomes.
