Many people do not have any idea:
The Heart is a pump, which delivers blood & oxygen around the body,
Heart Failure is a name for a collection of symptoms, which stop this happening!
Heart failure is a progressive disorder in which damage to the heart causes weakening of the cardiovascular system. It manifests by fluid congestion or inadequate blood flow to tissues. Heart failure progresses by underlying heart injury or inappropriate responses of the body to heart impairment.
Heart failure may result from one or the sum of many causes. It is a progressive disorder that must be managed in regard to not only the state of the heart, but the condition of the circulation, lungs, neuroendocrine system and other organs as well. Furthermore, when other conditions are present (e.g. kidney impairment, hypertension, vascular disease, or diabetes) it can be more of a problem. Finally, the impact it can have on a patient psychologically and socially are important as well.
