Afib and Stroke

Atrial fibrillation can pose a major risk factor for stroke. A person with Afib is five times more likely to have a stroke1 and about 15 percent of all people who have strokes also have Afib.

An estimated 15 percent of the 700,000 strokes in the United States each year are caused by untreated Afib. Since the heart doesn't beat normally in an Afib patient, it allows blood to pool in the left atrial appendage (LAA), a small pouch attached to the left atrium. In a major study of patients with Afib who had a stroke, more than 90 percent of the clots were found to exist in the LAA.1
