[Cardiogenic shock--severe complication of myocardial infarction].

Cardiogenic shock is the most common fatal complication of acute myocardial infarction. The conception of an extensive irreparable myocardial injury underlying the cardiogenic shock has changed especially with the results of the SHOCK study. In addition to the infarction injury, an acute inflammatory reaction, neurohumoral activation as well as improving myocardial stunning influence the development of shock. Mortality is high at the initial stage, whereas subsequent prognosis is equivalent to that seen in other infarction patients. Essential therapy consists in a prompt revascularization of the infarcted area and optimization of hemodynamics, if necessary by applying mechanical supportive therapies.
