It is most commonly due to an acute myocardial infarction (AMI) that is extensive, impairs right ventricular contractility, or causes a rupture of a papillary muscle. Other etiologies to consider include cardiotoxic drug effects, infection (myopericarditis, endocarditis), and mechanical dysfunction (valvular disease, pulmonary embolism, cardiac tamponade, myocardial contusion). Early stabilization and treatment are critical, as mortality approaches 50% for AMI complicated by cardiogenic shock.
