Answer

For stroke, this risk is estimated at approximately one third of patients with nonrheumatic atrial fibrillation. Males with hypertension, structural heart disease, left ventricular dysfunction, and diabetes may be at higher risk for thromboembolic complications. It is noteworthy that associated atrial fibrillation appears not to increase the risk of embolic complications significantly.
