Abstract
OBJECTIVE: Growing evidence indicates that both obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) may be closely associated with the prevalence of pulmonary embolism (PE). However, the relationship of overlap syndrome (OS) (coexistence of OSA and COPD) with PE is unclear. The purpose of this study was to investigate whether OS were associated with increased PE prevalence. METHODS: We performed a retrospective chart review of patients who underwent sleep study at Beijing An Zhen Hospital from 2011 to 2014. The association of OS with PE prevalence was estimated by using logistic regression models. RESULTS: In contrast to control patients (neither OSA nor COPD), those subjects with OS had higher odds of PE (OR9.61; 95%CI 4.02-21.31, p < 0.001) with significance persisting after adjusting for covariates (OR 5.66; 95%CI 1.80-16.18, p = 0.004). Meanwhile, patients with OS compared with those with isolated OSA also had significantly higher odds of PE in univariate (OR 4.79; 95%CI 2.04-10.33, p = 0.0007) and adjusted models (OR 3.89; 95%CI 1.27-10.68, p = 0.019). In subgroup analysis, patients with OS had higher odds of PE than control group among male subjects (OR 8.12, 95%CI1.86-31.87, p = 0.007) and patients ≥ 58years (OR 5.50, 95%CI 1.51-18.14, p = 0.012) in multivariable models. Percentage of total sleep time with saturation lower than 90% (T90) ≥ 2.6% was significantly associated with prevalence of PE (OR 4.72, 95%CI1.34-19.83, p = 0.015) in subgroup of patients older than 58. CONCLUSIONS: OS is independently associated with PE prevalence. Longitudinal studies are needed to better understand the relationship with incident PE.
