What is the risk of thromboembolism in chronic atrial fibrillation?
According to a 1997 study published in the American Journal of Cardiology, the risk of thromboembolism in chronic atrial fibrillation is significant. The study found that the risk of thromboembolism was higher in patients with a history of stroke or transient ischemic attack, more than one episode of atrial fibrillation, and a left atrial diameter greater than 40 mm.
