Acute myocardial infarction-related cardiogenic shock (AMI-CS) is a severe, life-threatening condition characterised by inadequate tissue perfusion due to the heart's inability to pump blood effectively. The pathophysiology of AMI-CS usually arises from the sudden loss of myocardial contractility, leading to a decrease in cardiac output and systemic hypoperfusion. In approximately 90% of AMI-CS cases, the left ventricle is the primary site of dysfunction.

Introduction: Hemorrhage is the leading cause of preventable deaths in trauma patients, resulting in 1.5 million deaths annually worldwide. Traditional trauma assessment follows the ABC (airway, breathing, circulation) sequence; evidence suggests the CAB (circulation, airway, breathing) approach to maintain perfusion and prevent hypotension.

Septic patients are routinely exposed to endogenously released and exogenously administered catecholamines, which may alter cardiac function and perfusion causing ischemia. Early during human septic shock, left ventricular ejection fraction (LVEF) decreases but normalizes in survivors over 7-10 days.

Cardiogenic shock represents a critical condition in which the heart is unable to maintain adequate circulation leading to insufficient tissue perfusion and end-organ failure. Temporary mechanical circulatory support offers the potential to stabilize patients, provide a bridge-to-recovery, provide a bridge-to-decision, or facilitate definitive heart replacement therapies. Although randomized controlled trials have been performed in infarct-related cardiogenic shock and refractory cardiac arrest, the optimal timing, appropriate patient selection, and optimal implementation of these devices remain complex and predominantly based on observational data and expert consensus, especially in non-ischaemic shock.
