What is congestive heart failure?

Heart failure occurs when the heart can not pump blood fast enough and effectively and your body to ensure an adequate supply of oxygen and nutrients. The result is a general fatigue, which is especially pronounced in physical exertion. Since the heart is not pumping enough blood to enter into the heart to stop, resulting in watering the lungs with fluid. This is the cause of breathlessness, which is usually the most distracting and limiting problem. Because of the poor blood flow through the kidneys they retain fluid in the body, which describes the problem worse. At the same time begin to swell legs and ankles, and other organs in the body.
