ABSTRACT
ObjectiveToinvestigatethecorrelationofobstructivesleepapnea(OSAS)andsilentbrain infarction (SBI) in elderly population. Methods A total of 1658 old subjects aged 60 in Beijing and Qingdao w ere screened. Polysomnography (PSG) w as used to conduct the diagnosis and grade of OSAS. MRI w as used to diagnose SBI. Results In al elderly subjects, the prevalences of OSAS and SBI w ere 32.1% and 22.4%. There w ere significant differences in the constituent ratio of the patients w ith hypertension and diabetes, as w el as apnea-hypopnea index (AHI), oxygen desaturation index (ODI), mean oxygen saturation and the low est oxygen saturation betw een the patients w ith OSAS of different severity and the control group. With the increased severity of OSAS, the incidence of SBI increased significantly. The incidences of patients w ith non-OSAS and mild, moderate and severe patients w ith OSAS w ere 13.2%, 30.5%, 43.5%, and 68.8%, respectively. There w as a significant difference betw een the 2 groups ( χ2 =13.365, P=0.004). Multivariable logistic regression analysis showed that hypertension (odds ratio [OR] 2.254, 95%confidence interval [CI] 1.325 to 8.347;P=0.002), diabetes melitus (OR 1.893, 95%CI1.471-8.432;P=0.003) and AHI ≥15 times/h (OR 3.106, 95%CI 1.583-12.571; P<0.001) were the independent risk factors for SBI in elderly population. Conclusions The incidence of OSAS w as higher in the elderly population aged over 60. The incidence of SBI in patients w ith OSAS w as significantly higher than that in patients w ith non-OSAS, and w ith the aggravation of OSAS, it show ed an increasing trend. Moderate to severe OSAS w as an independent risk factor for SBI in elderly population.
