Am J Resp Crit Care:呼吸暂停低通气事件持续时间可预测男性和女性死亡率

2018-10-22 xing.T MedSci原创

由此可见,呼吸事件持续时间较短作为低唤醒阈值的标志可预测男性和女性的死亡率。呼吸事件较短的个体可能易于增加通气不稳定性和/或增加自主神经系统反应,并且增加不良健康结局的可能性,强调评估阻塞性睡眠呼吸暂停的生理变化尤为重要。

阻塞性睡眠呼吸暂停是死亡的危险因素,但其诊断指标-呼吸暂停低通气指数,是一种较差的风险预测指标。该呼吸暂停低通气指数不能捕捉患者内部和患者之间的生理变异范围,例如低氧血症和睡眠片段化程度,这反映了气道塌陷的病理生理学作用、化学感受器反馈环增益和唤醒阈值的差异。近日,呼吸内科以及重症医学领域权威杂志Am J Resp Crit Care上发表了一篇研究文章,该研究旨在评估呼吸事件持续时间,一个反映觉醒阈值的遗传性睡眠呼吸暂停特征,预测全因死亡率的功能。

死亡风险作为事件持续时间的函数通过睡眠心脏健康研究中的Cox比例风险来估计,该研究是一项基于社区的前瞻性队列。研究人员还计算了针对性别的风险比率。

在11年的随访中,5712名参与者中有1190例患者发生死亡。在调整人口统计学因素(平均年龄为63岁; 52%为女性)、呼吸暂停低通气指数(平均为13.8;标准差为15.0)、吸烟和心脏代谢疾病患病率后,事件持续时间最短的个体全因死亡率风险比最为显著为1.31[95%置信区间为1.11-1.54]。这种关系在男性和女性中均可观察到,并且在中度睡眠呼吸暂停患者中最为明显(风险比=1.59 [1.11-2.28])。

由此可见,呼吸事件持续时间较短作为低唤醒阈值的标志可预测男性和女性的死亡率。呼吸事件较短的个体可能易于增加通气不稳定性和/或增加自主神经系统反应,并且增加不良健康结局的可能性,强调评估阻塞性睡眠呼吸暂停的生理变化尤为重要。
