    Yes atrial fibrillation can definitely increase the risk of stroke.
    The irregular and erratic contractions in the atrium can lead to stasis of blood and the formation of blood clots; if these blood clots detach from the atrium and travel to the brain they can block the blood supply to the brain and cause a stroke.
    Your health care professional can assess your risk of stroke based on a simple risk algorithm and advise if treatment is indicated to reduce your risk of stroke.
