Obstructive sleep apnea, stroke, and atrial fibrillation

Obstructive sleep apnea (OSA), stroke, and atrial fibrillation are related. OSA can increase risk of stroke. So can atrial fibrillation. OSA can make it harder for cardiologists to control atrial fibrillation. Here is a study that studied these three conditions. They monitored people with OSA to see if they had a stroke. In those that did have a stroke, atrial fibrillation was much more common. This suggests a relationship between atrial fibrillation and OSA in stroke development. And this relationship was true after adjusting for common conditions like age, diabetes, body mass index, etc.
