BACKGROUND: This study aims to investigate the relationship between estimated pulse wave velocity (ePWV) and all-cause mortality (ACM) and cardiovascular mortality (CVM) in patients with obstructive sleep apnea (OSA). METHOD AND RESULTS: A cohort study was conducted using data from the NHANES database (2005-2008, 2015-2018), focusing on adults with OSA. ePWV was calculated based on age and mean blood pressure. A weighted Cox regression model analyzed the association of ePWV with ACM and CVM, while restricted cubic spline (RCS) curves visualized this relationship. Kaplan-Meier (KM) survival curves assessed survival across different ePWV groups.The study involved 10,071 OSA patients with an average age of 48.46 years, with a follow-up period ending in December 2019 (average follow-up time: 102.10 ± 2.34 months). Results showed that increased ePWV correlated with higher ACM [hazard ratio [HR]: 1.25, 95% confidence interval [CI]: 1.20-1.31] and CVM (HR: 1.28, 95% CI: 1.21-1.36). RCS curves indicated stable mortality risks at ePWV ≤ 8.1 m/s, with rapid increases beyond this threshold. KM curves demonstrated poorer survival outcomes for OSA patients with elevated ePWV. CONCLUSION: Elevated ePWV levels are linked to increased ACM and CVM in OSA patients, suggesting that monitoring ePWV could help mitigate these risks and promote healthier longevity in this population.
背景:本研究旨在探讨阻塞性睡眠呼吸暂停(OSA)患者的估计脉搏波速度(ePWV)与全因死亡率(ACM)和心血管死亡率(CVM)之间的关系。 方法与结果:利用美国国家健康与营养检查调查(NHANES)数据库(2005 - 2008年,2015 - 2018年)的数据进行了一项队列研究,重点关注成年OSA患者。基于年龄和平均血压计算ePWV。采用加权Cox回归模型分析ePWV与ACM和CVM的关联,同时用受限立方样条(RCS)曲线直观展示这种关系。采用Kaplan - Meier(KM)生存曲线评估不同ePWV组的生存情况。该研究纳入了10,071例OSA患者,平均年龄48.46岁,随访期至2019年12月结束(平均随访时间:102.10 ± 2.34个月)。结果显示,ePWV升高与更高的ACM相关[风险比[HR]:1.25,95%置信区间[CI]:1.20 - 1.31]和CVM(HR:1.28,95% CI:1.21 - 1.36)。RCS曲线表明,ePWV≤8.1 m/s时死亡风险稳定,超过此阈值后迅速增加。KM曲线显示,ePWV升高的OSA患者生存结局较差。 结论:ePWV水平升高与OSA患者的ACM和CVM增加有关,这表明监测ePWV有助于降低这些风险,并促进该人群更健康长寿。
