We prospectively included 194 obstructive sleep apnea syndromepatients without cardiovascular disease (mean age 56.5±12.5 years) who were undergoing sleep tests. An overnight full laboratory polisomnography examination was conducted on each patient. The patients were divided into 3 groups according to the apnea-hypopnea index (AHI) (1) AHIlow group 5≤AHI<15, (2) AHImid group 15<AHI≤30, and (3) AHIhigh group AHI>30.
RESULTS:
The highest MPV values were found in the AHIhigh group compared with other groups (p<0.05 for all). Multiple linear regressionanalysis indicated that the MPV was associated with the AHI (β=0.500, p<0.001) and the high sensitivity C-reactive protein (hs-CRP) level (β=0.194, p=0.010).
