Cardiogenic shock is a state in which the heart has been damaged so much that it is unable to supply enough blood to the organs of the body.
Alternative Names
Shock - cardiogenic
Causes, incidence, and risk factors
Shock occurs whenever the heart is unable to pump as much blood as the body needs.
The most common causes are serious heart complications. Many of these occur during or after a heart attack (myocardial infarction). These complications include:
Dangerous heart rhythms, such as ventricular tachycardia, ventricular fibrillation, or supraventricular tachycardia
Very slow heart rhythm (bradycardia) or heart conduction block
Tear or rupture of the wall (septum) between the left and right ventricle
Tear or rupture of the muscles or tendons that support the heart valves, especially the mitral valve
A large section of heart muscle that no longer moves well or does not move at all
Rupture of the heart muscle due to damage from the heart attack
Symptoms
Profuse sweating, moist skin
Rapid breathing
Rapid pulse
Restlessness, agitation, confusion
Skin that feels cool to the touch
Pale skin color or blotchy (mottled) skin
Weak (thready) pulse
Decreased mental status
Loss of ability to concentrate
Loss of alertness
Coma
Signs and tests
An examination will reveal:
Low blood pressure (less than 90 systolic)
Blood pressure may drop more than 10 points when you stand up after lying down (orthostatic hypotension)
Weak (thready) pulse
To diagnose cardiogenic shock, a catheter (tube) may be placed in the pulmonary artery (right heart catheterization). Measurements often indicate that blood is backing up into the lungs and the heart is not pumping properly.
