Cardiogenic shock

Cardiogenic shock is an extreme form of cardiac failure.

The characteristic features are:

• poor tissue perfusion:
  • poor cerebral function
  • cool extremeties
  • oliguria
• hypotension
• poor cardiac output

Cardiogenic shock is most commonly caused by myocardial infarction.

• cardiogenic shock occurs in up to 10% of patients immediately following acute myocardial infarction and is associated with mortality rates of nearly 40% at 30 days and 50% at 1 year. Current evidence and clinical practice guidelines support immediate revascularization of the infarct-related coronary artery as the primary therapy for cardiogenic shock following acute myocardial infarction
