摘要: 目的:探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)与心血管疾病危险因素的相关性。方法:选取行睡眠监测确诊为OSAHS并准备手术的患者228例,分别测定血常规(红细胞压积,血红蛋白,红细胞)和血液生化指标(高密度脂蛋白,低密度脂蛋白,总胆固醇,甘油三脂,肌酐,尿素氮),并分析与呼吸暂停低通气指数(AHI)、呼吸暂停指数(AI)、低通气指数、最低血氧饱和度的相关性。将228例患者分为3组:轻度组(5≤AHI<15)、中度组(15≤AHI<30)和重度组(30≤AHI),分别统计各组发病率,并行ROC分析评估AHI、AI诊断OSAHS伴心血管疾病危险因素的价值。结果:①轻度组和中度组并发心血管疾病危险因素的发病率无明显差异(χ2=0.428,P>0.05),而重度组发病率明显大于轻度组和中度组(χ2=12.89,P<0.05)。ROC分析示AHI、AI的ROC曲线下面积分别为0.678、0.679,有一定诊断价值。②血常规与AHI有一定的正相关性(r=0.176~0.194,P<0.05)。结论:OSAHS可能是导致心血管疾病的病因之一。

Abstract: Objective: To explore the roles of cardiovascular disease in obstructive sleep apnea hypopnea syndrome.Method: All 228 OSAHS patients underwent the examination of biochemical and complete blood count. The correlation analysis between AHI,AI,HI,LSaO2, complete blood count,and biochemical examination were employed.Two hundred and twenty-eight cases were divided into 3 groups according to sleep apnea hypopnea index(AHI):group 1(5≤AHI<15),group 2(15≤AHI<30),group 3(30≤AHI). Morbidity of diseases in each group was calculated and the value of AHI and AI for morbidity was analyzed by using ROC curve.Result: ①No statistically significant difference was found between group 1 and group 2(χ2=0.428,P>0.05 ).There was significant difference between group 3 and group1,2(χ2=12.89,P<0.05).The areas under the ROC curves of AHI and AI were 0.678 and 0.679,repectively. ②There was significant positive correlation between AHI and complete blood count parameters(r=0.176 to 0.194,P<0.05).Conclusion: OSAHS may be one of the predisposing factors of cardiovascular disease. -
