Heart failure
Heart failure is a long-term condition in which the heart cannot pump blood around the body as effectively as it should. This does not mean that the heart has stopped working. Instead, the heart may be too weak to pump enough blood, too stiff to fill properly, or both. Because the heart cannot meet the body's needs efficiently, fluid can build up in the lungs, legs, ankles and other parts of the body. This can lead to symptoms such as breathlessness, tiredness and swelling of the legs. Heart failure can develop gradually or sometimes appear suddenly. It can affect people of different ages, although it is more common in older adults. Heart failure is usually a long-term condition, but appropriate treatment, regular medical follow-up and lifestyle changes can help control symptoms, improve quality of life and reduce the risk of hospitalisation.
