Overview
Heart failure means the heart is not pumping blood around the body as well as it should, so fluid builds up and organs get less blood than they need. It does not mean the heart has stopped. It usually develops after other heart problems like a heart attack or long-standing high blood pressure. It causes breathlessness, tiredness and swelling, and while it is a serious long-term condition, medicines and lifestyle changes can control symptoms and help people live longer, fuller lives.
Symptoms
- Breathlessness on exertion and when lying flat
- Swelling of the ankles, legs or belly
- Tiredness and weakness
- Waking at night short of breath
- Rapid weight gain from fluid and a persistent cough
When to see a doctor
See a doctor for breathlessness, swelling or unusual tiredness, and urgently if breathing suddenly worsens or you cannot lie flat.
Emergency — call 108 or go to the nearest hospital
- Sudden severe breathlessness, gasping while sitting up, frothy or pink sputum, chest pain or fainting — call 108 immediately
Causes
Damage or strain from a previous heart attack, long-standing high blood pressure, heart valve or muscle disease, and uncontrolled diabetes.
