Brief Summary

One of the most likely mechanisms explaining the sleep apnea (SA)-induced increase in metabolic syndrome is the oxidative stress (OS) induced by intermittent hypoxia (IH). There are clear-cut signs of OS in postmenopausal women that may be further enhanced by SA. In rats exposed to IH, an estradiol receptor alpha agonist decreases the level of OS markers. The aims of this study are to compare OS in apneic and non-apneic postmenopausal women and to demonstrate that OS will improve after 3 months of treatment with ER alpha agonists (Duavive) in apneic post-menopausal women.
