Heart failure is a serious condition where the heart has difficulty pumping enough blood around the body.
Heart failure occurs when the heart muscle has become too weak or too stiff to pump blood through the body as effectively as normal.
Sometimes the symptoms of heart failure can develop quickly (acute heart failure). However, they usually develop gradually, over time (chronic heart failure).
Heart failure does not usually have a single cause. There are a number of health conditions that increase your risks of developing heart failure including:
- coronary heart disease
- high blood pressure
- heart attack
- heart muscle damage (cardiomyopathy)
- heart rhythm disturbance (atrial fibrillation)
- heart valve disease (damage or problems with the heart’s valves).
In most cases, heart failure is a lifelong condition that cannot be cured.
Personal story: heart failure
Being diagnosed with heart failure can be both emotionally and practically challenging. Listening to others who have experienced similar situations is often re-assuring and can be helpful for you, your loved ones or when preparing questions for your doctor or a specialist.
