Abstract：Objective To observe the night blood pressure in obstructive sleep apnea-hypopnea syndrome (OSAHS) patients with normal day-time blood pressure. Methods According to level of night blood pressure, 50 OSAHS patients were divided into two groups: patients with hypertension in sleeping and patients without hyperten-sion in sleeping. Polysomnogram and arterial pressure were tested. Serum endothelin (ET) and calcitonin gene-re-lated peptide (CGRP) levels were measured and compared. Results Eighteen OSAHS patients had hypertension in sleeping. Among them 16 patients had hypertension at morning. The apnea hypopnea index (AHI),the lowest SaO2、the serum levels of ET and ET/CGRP ratio in the OSAHS patients with hypertension in sleeping were higher than those in OSAHS patients without hypertension in sleeping. Conclusion A part of OSAHS patients with hyper-tension in sleeping might be unnoticed only by day-time blood pressure.
