Are there complications associated with AF?

The main risk associated with AF is stroke. As the blood is not being properly pumped away from the heart, it may collect or ‘pool’ and a clot could develop in the heart. If the clot leaves the heart and enters the small blood vessels of the brain, the flow of blood may block and result in a stroke.

People with AF are more likely to have a stroke compared with people who do not have AF.

If your atrial fibrillation is not well controlled, it may start to weaken your heart. In extreme cases, it can lead to heart failure where your heart cannot pump blood around your body efficiently.
