Background: Obstructive sleep apnea (OSA) is associated with several cardiovascular diseases. However, the mechanisms are not completely understood. Recent studies have shown that OSA is associated with multiple markers of endothelial damage. We hypothesized that OSA affects functional and structural properties of large arteries, contributing to atherosclerosis progression. Methods and Measurements: Twelve healthy volunteers, 15 patients with mild to moderate OSA, and 15 with severe OSA matched for age, sex, and body mass index were studied by using (1) full standard overnight polysomnography; (2) carotid-femoral pulse wave velocity with a noninvasive automatic device; and (3) a high-definition echo-tracking device to measure intima-media thickness, diameter, and distensibility. All participants were free of hypertension, diabetes, and smoking, and were not on any medications. Patients with OSA were naive to treatment. Main Results: Significant differences existed between control subjects and patients wit...
