Abstract:
Objective To investigate the influence of nasal continuous positive airway pressure (nCPAP) treatment on cardiovascular risk factors in patients with obstructive sleep apnea-hypopnea Syndrome (OSAHS). Methods Thirty-one patients with newly diagnosed OSAHS were divided into 3 groups based on the status of nC-PAP treatment: group 1,10 patients with nCPAP > 4 hrs/night;group 2:9 patients with nCPAP < 4 hrs/night;group 3:12 patients without nCPAP treatment. Serum cardiovascular risk factors (i. e. ,C-reactive protein(CRP), total cholesterol, triglycerides, highdensity lipaprntein cholesterol (HDL-C), low-density lipoprotein cholesterol, apo-lipoprotein A-I (ApoA-1), and apolipoprotein B (ApoB) ) were measured at baseline and 6 months after nCPAP treatment. Results ① There was no significant difference on age,body mass index,blcod pressure,Epworth sleepi-ness scale (ESS) and saturation of blood oxygen (SPO_2) between the 3 groups (P>0.05). ②In group 1, ESS, SPO_2 minimum SPO_2 were significantly improved (3.20±2.80,93.80±2.01 and 84.10±6.17, respectively) compared to baseline (13.30±5.20,88.60±4.14 and 69.60±11.80, respectively) (P<0.01). Moreover, in group 2, there were significant improvement on ESS, SPO_2 and minimum SPO2 (4.95±2.67,94.20±1.46 and 85.20±4.97, respectively) compared to baseline (12.80±5.50,89.10±5.11 and 73.70±12.50, respectively) (P<0.01). ③In group 1 ,significant decreases in the levels of CRP,total cholesterol was observed (P=0.021 and 0.038). ④In group 2, group 3 there were slightly decrease of CRP after treatment, but the difference did not reach statistieal significance. Conclusions Good compliance to nCPAP treatment decreases the serum levels of cardiovas-cular risk factors, indicating a beneficial effect on the overall cardiovascular disease prevention and control.
