Oral anticoagulants are effective at preventing strokes
in patients who have atrial fibrillation without significantly
increasing hemorrhage. The more risk factors for stroke that a
patient has along with atrial fibrillation the more benefit from
oral anticoagulants. The benefit of stroke prevention needs to be
weighed against risk of hemorrhage, life style change, medical
monitoring, and cost.
