    Study Notes

    Cardiogenic Shock Overview

    • Leading cause of mortality in cardiogenic shock is due to the failure of the heart to pump effectively, often resulting in multi-organ dysfunction.
    • Clinically, cardiogenic shock presents with symptoms such as hypotension, tachycardia, decreased urine output, altered mental status, and cold, clammy skin.

    Causes and Mechanisms

    • Primary cause of systemic hypoperfusion in cardiogenic shock is reduced cardiac output, which leads to inadequate blood flow to vital organs.
    • Myocardial infarction is the condition that accounts for the majority of patients experiencing cardiogenic shock, often resulting from coronary artery disease.
