Clinical analysis of 93 patients with obstructive sleep apnea hypopnea syndrome / 中国实用内科杂志

ABSTRACT

Objective To investigate the serum levels of vascular endothelial growth factor(VEGF)in patients with obstructive sleep apnea hypopnea syndrome(OSAHS),and make a primary relative study on the relationship between VEGF and pH.Methods Thirty-nine patients with mild to moderate OSAHS,36 patients with severe OSAHS and 18 healthy snorers who had been admitted to the First Hospital Affiliated to Wenzhou Medical College from Feb.2003 to Sep.2004 were enrolled in this study.The serum levels of VEGF were detected in all patients at 7:00 AM the next day after the detection of polysomnography(PSG).Additionally 31 patients with OSAHS were detected by doppler echocardiography to get the values of pulmonary artery pression.Results There was nocturnal hypoxia in patients with OSAHS compared with healthy snorers,and the degree of nocturnal hypoxia was depended with the grade of OSAHS(both achieved statistical difference)by the detection of PSG.The levels of VEGF was significantly higher in patients with severe OSAHS than in healthy snorers(P
