Objective:To investigate the significance of the vascular endothelial growth factor(VEGF) levels in obstructive sleep apnea syndrome(OSAS) associated with hypertension. Methods:The VEGF levels were measured in OSAS group(n = 36),OSAS plus hypertension group(n = 14) and control group(n = 20),before and after the continuous positive airway pressure(CPAP) treatment in OSAS plus Hypertension group respectively, and differences between each two groups were investigated. Results:The VEGF levels in simple OSAS group(n = 36)[(81.76 ± 10.81)pg/ml],and in OSAS plus hypertension group(n = 14)[(92.35 ± 7.49)pg/ml] were significant higher than that in the control group(n = 20)[(70.01 ± 5.71)pg/ml] espectively(P < 0.05), but there was no significant difference among the subgroups of OSAS(P > 0.05). The plasma VEGF levels in OSAS plus hypertensive group changed significantly from the baseline level(n = 14)[(92.35 ± 7.49)pg/ml] to the level[(72.56 ± 4.41)pg/ml ] after one week of CPAP treatment(P <0.05). Conclusion:Plasma VEGF levels in OSAS and hypertension patient were both higher than that in control group. Vascular endothelial growth factor(VEGF) may relieve OSAS and reduce the complication of cardiovascular disease by promoting vascular endothelial cell proliferation and angiogenesis as well as improving tissue hypoxia. There was a decrease in VEGF concentrations in OSAS plus hypertension group after CPAP treatment.
