The main function of the heart is to supply oxygenated blood to different parts of the body. It pumps oxygen-rich blood into the circulatory system through the arteries. Congestive heart failure (CHF) is a medical condition wherein the heart’s pumping action weakens considerably. As a result of this weakened action, the tissues of the body do not receive adequate blood and oxygen.

Congestive heart failure does not mean that the heart completely stops working. In this condition, the heart loses its ability to pump sufficient amounts of blood needed by the body to perform its various tasks. As a result, the blood also does not circulate properly which often leads to accumulation of blood (swelling) in some parts of the body. People diagnosed with congestive heart disease often have swollen legs and hands. The ability of the kidney to dispose water and sodium is also hampered. If fluid collects in the lungs, then shortness of breath is also experienced.

In the early stages of congestive heart failure, the heart responds by enlarging itself to meet the needs of the body. It starts pumping faster to increase the output of blood. As the pumping activity becomes stronger, more blood is circulated through the entire body. This helps the body in performing its functions properly. However, over a period of time, the heart muscle weakens and the functioning of the heart slows down. Eventually, people suffering from this condition experience health problems such as restlessness and chest pain. Read the rest of this entry »
