摘要 目的探讨中年睡眠呼吸暂停综合征(obstructive sleep apnea-hypopnea syndrome,OS-AHS)对颈动脉内膜中层厚度影响,及其机制。方法收集我院58例中年睡眠呼吸暂停综合征患者及60例单纯肥胖为对照组,采用彩超检测颈动脉内膜中层厚度(intima-media thickness,IMT),同时测定血清超敏C-反应蛋白(hish-sensitivity-C response protein,hs-CRP)和血浆同型半胱氨酸(Homo-cysteine,Hcy)指标,分析其差异及相关性。结果 1)与单纯肥胖组比较,两组间年龄、性别、BMI无明显统计学差异(P>0.05),而AHI,平均SaO2%和平均最低SaO2%有显著统计学差异;(P<0.05);2)OSAHS患者IMT、hs-CRP和Hcy较单纯肥胖者明显异常,差异有统计学意义(P<0.05);3)相关性分析显示,AHI与IMT、hs-CRP和Hcy呈正相关(r=0.562,P=0.036;r=0.639,P=0.019;r=0.591,P=0.021);平均SaO2%与hs-CRP和Hcy负相关(r=-0.489,P=0.041;r=-0.612,P=0.034);最低SaO2%与IMT和Hcy负相关(r=-0.511,P=0.039;r=-0.635,P=0.022);IMT与hs-CRP和Hcy呈正相关(r=0.601,P=0.024;r=0.572,P=0.041)。结论中年OSAHS患者颈动脉内膜厚度明显增厚,其是监测OSAHS患者动脉粥样硬化的重要无创指标。而hsCRP和Hcy在其病理过程中起着重要作用,因此为早期干预OSAHS患者动脉粥样硬化过程提供新的靶点。
