Could sex explain why sleep apnea harms women's hearts more?
NCT ID NCT04436731
First seen Jul 28, 2026 · Last updated Jul 29, 2026 · Updated 1 time
Summary
This study investigates whether sex and obesity influence how blood vessels respond to low oxygen levels, a key factor in sleep apnea. Researchers will compare healthy-weight and obese men and women to see if differences in vessel constriction and dilation help explain why women with sleep apnea face higher cardiovascular risks. The goal is to uncover mechanisms that could lead to better, sex-specific therapies.
