What is the risk of early recurrence of a stroke in patients with atrial fibrillation?
The risk of early recurrence of a stroke in patients with atrial fibrillation is high - for example, the International Stroke Trial reported a 4.8% risk of recurrent stroke in those with atrial fibrillation within the first week, while other studies suggest a recurrence risk of between 0.4% and 1.3% per day in the first 7 days.
