Causes of Congestive Heart Failure

There are several causes of congestive heart failure, a syndrome brought about by the weakening of the heart. Some of these are:

  • Damage to the heart muscles.
  • Damaged heart valves.
  • Blockage of the coronary arteries, resulting in a lower supply of blood to the heart muscles. This can result in heart attacks.
  • Repeated exposure to toxins like cigarette smoke, alcohol and cocaine.
  • Infection.
  • High blood pressure or hypertension which results in a thickening of the heart muscle (left ventricular hypertrophy)
  • Congenital heart diseases
  • Pericardial disease that does not allow the heart to fill completely
  • Heart arrhythmias
  • Often it is not one single factor which causes congestive heart failure but a combination of factors. There are times when there is no specific underlying cause. This is known as idiopathic cardiomyopathy or heart muscle disease of unknown origin.
