Both men and women appear to have a greater risk of stroke if they suffer from obstructive sleep apnea, researchers found.
Through up to 14 years of follow-up, stroke risk increased along with the obstructive sleep apnea index to a similar extent in both men and women, according to Suzanne Bertisch, MD, instructor in medicine at Harvard Medical School/Beth Israel Deaconess Medical Center in Brookline, Mass.
The 5-year probability of having a stroke with the least severe obstructive sleep apnea index was 0.4% for women and 0.6% for men, while the probability in the highest quartile of obstructive sleep apnea severity was 1.2% for women and 1.8% for men, she reported at the American Thoracic Society meeting in San Diego.
At 10 years, the probability of having a stroke if you were in the lowest quartile of the sleep apnea index was 0.9% for women and 1% for men, while the probability of having a stroke in the highest quartile of the apnea index was 2.3% in women and 3.1% in men.
All results were adjusted for various confounders, including age, race, education level, smoking status, diabetes, hypertension, and body mass index, she said.
