Eur Respir J:安第斯高地人群心血管疾病与睡眠呼吸紊乱相关!

2017-06-18 xing.T MedSci原创

在高海拔地区人群中,夜间低氧血症和睡眠呼吸暂停与患者不同的心血管结局相关,过多的红细胞增多症和葡萄糖不耐受分别会导致不同的风险。

高海拔地区睡眠呼吸障碍(SDB)与心脏代谢结局之间的相关性还没有被评估。近日,呼吸疾病领域权威杂志Eur Respir J上发表了一篇研究文章,研究人员秘鲁高地(3825 m)进行了夜间多导睡眠监测。

研究人员采用多变量线性回归模型来评估SDB的指标与血红蛋白、血糖耐受性(糖化血红蛋白A1c(HbA1c))、空腹血糖、稳态模型评估的胰岛素抵抗和β细胞功能(分别为HOMA-IR和HOMA -β)、血压和血脂之间的相关性,同时,调整了年龄、性别、体重指数(BMI)和醒觉时的氧合。

参与者(n=187;91名为男性)年龄(中位数(四分位间距))为52(45-62)岁,并且体重指数为27(24.3-29.5)kg/m2以及在清醒时87%(85-88%)的氧合血红蛋白(动脉血氧饱和度)。在充分调整的模型中,恶化的夜间低氧血症与男性血红蛋白升高相关(P=0.03),独立于醒觉时的氧合和呼吸暂停低通气指数(AHI),而醒觉时的氧合恶化与老年女性血红蛋白升高相关(P=0.02)。与此相反,AHI与HbA1c升高独立相关(P<0.05)。在单变量模型中,夜间低氧血症与较高的HbA1c、HOMA-IR和HOMA -β相关(分别有P<0.001,P=0.02,P=0.04),而AHI与HOMA-IR、收缩压和甘油三酯升高相关(分别有P=0.02,P=0.01,P<0.01)。在完全调整模型中,这些相关性并不显著。

在高海拔地区人群中,夜间低氧血症和睡眠呼吸暂停与患者不同的心血管结局相关,过多的红细胞增多症和葡萄糖不耐受分别会导致不同的风险。
