Congestive heart failure is a condition in which the heart cannot pump enough oxygenated blood to meet the needs of the body's other organs. The heart keeps pumping, but not as efficiently as a healthy heart. Usually, the loss in the heart's pumping action is a symptom of an underlying heart problem.
Symptoms may include:
- weight gain
- visible swelling of the legs and ankles (due to a build-up of fluid) and, occasionally, the abdomen
- shortness of breath during rest or exercise
- fatigue
- loss of appetite and nausea
- persistent cough - often produces mucus or blood-tinged sputum
