About Heart Failure

Heart failure, also known as congestive heart failure, is a long-term chronic condition in which the heart can no longer pump oxygen rich blood to the rest of the body. It can affect either the right or left sides of the heart, but more often than not both sides of the heart are involved. Heart failure is most often caused by coronary artery disease (CAD), which is when the small blood vessels that supply both blood and oxygen to the heart become constricted. Heart failure can also occur when an infection weakens the heart, this is called cardiomyopathy.
