Abstract

Objectives

Obstructive sleep apnea acts as a potential risk factor for the development of cardiovascular disease. We undertook collaborative meta-analyses to clarify the risk of aortic dissection among adults suffering obstructive sleep apnea.

Methods

A systematic search of the databases (PubMed, Embase, and Cochrane Library) was performed. Studies reporting on the association between obstructive sleep apnea and aortic dissection were included. Information on 424 cases of aortic dissection in 56,291 patients from one cohort, four case–controls, and two cross-sectional studies were included in this study.

Results

The summary suggested that patients with obstructive sleep apnea are associated with an overall significant 60% increase in the risk of aortic dissection, compared to unexposed patients (odds ratios 1.60; 95% confidence interval 1.01–2.53), with a significantly higher apnea–hypopnea index (mean difference 10.71; 95% confidence interval 7.46–13.96). Moreover, a greater relation was found between moderate-to-severe obstructive sleep apnea and aortic dissection (odds ratios 4.43; 95% confidence interval 2.59–7.59). Adverse outcomes obtained by sleep study such as oxygen desaturation index (mean difference 10.51; 95% confidence interval 7.54–13.48), average SaO₂ (−1.36; 95% confidence interval −2.63 to −0.09), and minimum SaO₂ (−3.63; 95% confidence interval −5.27 to −1.98) were correspondingly related to patients with aortic dissection.

Conclusions

Obstructive sleep apnea, especially moderate-to-severe obstructive sleep apnea, may impose an additional risk of suffering from aortic dissection with a potential mechanism including intermittent hypoxia.
