Heart failure is the inability of the heart to pump adequate amounts of blood around the body, as a result the body is starved of the oxygen and the nutrients which it needs to function efficiently.
When heart failure occur, the blood backs up behind the heart causing increased pressure in the lungs, because of the accumulation of fluids shortness of breath occur, regardless of whether the person is lying down, resting or during physical exertion. Fatigue and dizziness also occur due to reduced blood flow to the brain and muscles. The heart beat becomes irregular as it tries to compensate for the inadequate supply of oxygenated blood circulating in the body. Fluid retention known as oedema also occurs causes swelling of the legs, ankles and abdomen.
