Cardiogenic Shock

Emergency and Critical CareAll SpeciesNew

Key Points

Cardiogenic shock is a life-threatening form of circulatory shock caused by a primary cardiac pump failure, resulting in inadequate tissue perfusion
It is characterised by reduced cardiac output, poor perfusion and elevate cardiac filling pressures
Common causes include cardiomyopathies, severe arrhythmias and advanced primary cardiac disease
Diagnosis requires assessment of perfusion parameters and identification of impaired cardiac function
Supporting cardiac output is central to treatment but, unlike other forms of shock, aggressive fluid resuscitation is contraindicated as it can worsen cardiac function
Without intervention, cardiogenic shock can rapidly progress to multi-organ dysfunction syndrome (MODS) and death
