Cardiogenic shock occurs when the heart is unable to pump blood and maintain an adequate blood supply for other vital organs. Cardiogenic shock has a death rate of about 60% and is the major cause of death in patients hospitalized for a heart attack. Getting immediate medical treatment for a heart attack is important in preventing the development of cardiogenic shock. The June 7, 2006, issue of JAMA includes an article about improving long-term survival for patients who have had cardiogenic shock.

CAUSES OF CARDIOGENIC SHOCK

• Myocardial Infarction (heart attack)
  
• Myocarditis—a condition in which the heart does not pump properly because the heart muscle is inflamed and diseased
  
• Valvular Heart Disease—damage to heart valves interrupts blood flow
  
• Cardiac Arrhythmias—severe irregular heart rhythms cause uncoordinated blood flow through the heart
  
• Obstruction—certain conditions apply pressure or compress the heart, not allowing it to function as a pump. Pericardial tamponade (collection of blood . . . [Full Text of this Article]
