[Cardiogenic shock : etiology and management].

Cardiogenic shock is one of the four types of circulatory shock (cardiogenic, distributive, hypovolemic and obstructive). It is a serious complication associated with a hypoperfusion state of terminal organs and possible multivisceral failures, with a high mortality rate of nearly 50 %. It is secondary to an acute myocardial infarction in 8 out of 10 cases but only complicates it in 5 to 10 %. It is more frequently encountered in pluri-troncular coronary diseases. Coronary revascularization and supportive care are the main treatments.
