Cardiogenic shock, unrelated to mechanical complications, as current complication following acute myocardial infarction

**Definition:** The most severe clinical expression of left ventricular failure and is associated with extensive damage to the left ventricular myocardium after acute myocardial infarction, unrelated to a mechanical defect such as ventricular septal or papillary muscle rupture. Shock is defined as systolic blood pressure (BP) < 90 mmHg and organ hypoperfusion.
