Purpose The pathogenesis of cardiovascular disease (CVD) in patients with obstructive sleep apnea (OSA) is unclear. Several studies have suggested that CVD may be caused by oxidative stress from chronic intermittent hypoxia and associated vascular endothelial dysfunction. Oxidative stress in patients with OSA can induce endothelial cell apoptosis, aggravate vascular endothelial damage, and promote the expression of redox-sensitive genes and adhesion molecules. No meta-analysis has explored whether or not OSA is related to nitric oxide (NO). Method To assess the association between serum/plasma NO levels and OSA, we performed a meta-analysis of the literature on the subject to grade the strength of evidence. Results OSA was significantly related to decreased serum or plasma NO levels (WMD = − 11.66, 95% CI − 17.21 to − 6.11; P < 0.01). Among the studies analyzed, there was high degree of heterogeneity ( I 2 = 79%, P < 0.01). Sensitivity analysis showed that after omitting any single study or converting a random effects model (REM) to a fixed effects model (FEM), the main results still held. Conclusions This meta-analysis suggests a strong correlation between OSA and serum or plasma NO levels which may explain the link between intermittent hypoxia of OSA and risk of CVD. The strength of this finding may spur further basic and clinical research into vascular endothelial dysfunction in patients with OSA.

一氧化氮 (NO) 水平在阻塞性睡眠呼吸暂停低通气综合征患者中的作用:荟萃分析

目的阻塞性睡眠呼吸暂停(OSA)患者心血管疾病(CVD)的发病机制尚不清楚。一些研究表明 CVD 可能是由慢性间歇性缺氧和相关血管内皮功能障碍引起的氧化应激引起的。OSA患者氧化应激可诱导内皮细胞凋亡,加重血管内皮损伤,促进氧化还原敏感基因和粘附分子的表达。没有荟萃分析探讨 OSA 是否与一氧化氮 (NO) 相关。方法 为了评估血清/血浆 NO 水平与 OSA 之间的关联,我们对该主题的文献进行了荟萃分析,以对证据强度进行分级。结果 OSA 与血清或血浆 NO 水平降低显着相关(WMD = - 11.66,95% CI - 17.21 至 - 6.11;P < 0.01)。在分析的研究中,存在高度异质性(I 2 = 79%,P < 0.01)。敏感性分析表明,在省略任何单一研究或将随机效应模型(REM)转换为固定效应模型(FEM)后,主要结果仍然成立。结论 这项荟萃分析表明 OSA 与血清或血浆 NO 水平之间存在很强的相关性,这可以解释 OSA 间歇性缺氧与 CVD 风险之间的联系。这一发现的力量可能会刺激对 OSA 患者血管内皮功能障碍的进一步基础和临床研究。结论 这项荟萃分析表明 OSA 与血清或血浆 NO 水平之间存在很强的相关性,这可以解释 OSA 间歇性缺氧与 CVD 风险之间的联系。这一发现的力量可能会刺激对 OSA 患者血管内皮功能障碍的进一步基础和临床研究。结论 这项荟萃分析表明 OSA 与血清或血浆 NO 水平之间存在很强的相关性,这可以解释 OSA 间歇性缺氧与 CVD 风险之间的联系。这一发现的力量可能会刺激对 OSA 患者血管内皮功能障碍的进一步基础和临床研究。
