AFib and Stroke

AFib and Stroke

Atrial fibrillation is a risk factor for stroke. About 15 percent of all people who have strokes have AFib. Because of the irregular and chaotic flow of blood through the heart, small blood clots can form in the heart chambers when you have atrial fibrillation. These clots can travel through the bloodstream to the brain, causing a stroke. This is why people with chronic AFib are usually on blood-thinning medications.
