A life-threatening condition in which the heart suddenly can't pump enough blood.

Cardiogenic shock is a rare, life-threatening condition. The heart suddenly can't pump enough blood to support the body's needs. It's often due to a severe heart attack. But damage to the heart or heart valves and drug overdoses also can cause it. Emergency treatment is needed to prevent organ damage and death.

Symptoms include rapid breathing, sudden rapid heartbeat, severe shortness of breath, loss of alertness and a weak pulse. The person may look pale and have cold skin.

Emergency life support is needed. This includes oxygen and a breathing machine. Medicines are given to help the heart pump better. A heart procedure or surgery is done to restore blood flow through the heart.
