Eductional Objective: Cardiogenic shock and abrupt left ventricular failure (LV) can both exacerbate myocardial infarction. In cardiogenic shock, elevated LV end-diastolic pressure is transferred backward, increasing the pressure in the pulmonary capillary wedge (which results in pulmonary edema), as well as the pressure in the central veins. A significantly reduced cardiac output results in hypotension and a lower coronary perfusion pressure.
