    What causes Cardiogenic Shock ?
    ### Response:
    Immediate Causes
                
Cardiogenic shock occurs if the heart suddenly can't pump enough oxygen-rich blood to the body. The most common cause of cardiogenic shock is damage to the heart muscle from a severe heart attack.
                
This damage prevents the hearts main pumping chamber, the left ventricle (VEN-trih-kul), from working well.
