Abstract:
Objective To study the correlation between the obstructive sleep apnea-hypopnea syndrome (OSAHS) and hypertension by monitoring nocturnal blood pressure fluctuation in patients.Methods 95 patients with OSAHS and hypertension (group A) and 95 patients with OSAHS only (group B) were selected and their body mass index, the ratio of neck circumference and height , the blood pressure at time of visit were recorded.At least 7 hours, polysomnography(PSG) was performed for every patient , meanwhile, the blood pressure before sleep, at night and right after wake-up were also collected.The two groups' data was compared and analyzed.Re-sults There was no statistical difference in the body mass index and neck circumference/height between the two groups.No significant difference was found in the highest blood pressure in patients with different severity of OS-AHS.There was no statistical correlation between AHI and systolic blood pressure(SBP) difference of sleep and right after wake, so was AHI and diastolic blood pressure (DBP) difference of before sleep and sleep and bedtime (P > 0.05).But there was correlation between AHI and the different value of SBP before sleep and sleep, so is AHI and DBP diferenee of right after wake and sleep (P > 0.05).Conclusions There is correlation between AHI and the different value of SBP before sleep and sleep, so was AHI and DBP diferenee of right after wake and sleep.Measure of different time-points blood pressure at night can avoid interrupting the sleep state of patients, will help better evaluate cardiovascular complications and prognosis of patients with OSAHS .
