  Background: Endothelial dysfunction is often present in subjects with obstructive sleep apnea (OSA) on walking up. Although the intermittent hypoxia has been suggested as a main cause of endothelial dysfunction in these subjects, the precise mechanism of this event is still unclear. The aim of this study was to demonstrate the correlation between the level of hypoxia during sleep with arterial blood pressure and plasma concentration of nitrite. Methods: Non-smoker subjects were included in a cross-sectional study. They underwent systolic and diastolic blood pressure (SBP and DBP) measured at bed before sleep and on walking up, overnight polysomnography (PSG), and measurement of nitrite in plasma from peripheral blood at walking up. Results: Sixty-five subjects with mean age of 58 ± 12 years were included in this study. The male-female ratio was 0.9 and BMI was 23.3 ± 3.4.. View More»
