Researchers in Connecticut have found that obstructive sleep apnea (OSA) in patients with atrial fibrillation (AF) appears to be an independent predictor of stroke. The authors also found that ischemic stroke was more common in AF patients with OSA when compared with those who did not have OSA (25.4% vs 8.2%). They concluded that this association may have important clinical implications in ischemic stroke risk stratification.
