[Effects of different accompanying symptoms of obstructive sleep apnea on the risk of cardiovascular and cerebrovascular and diabetes events].

To investigate the effects of different accompanying symptoms on the risk of cardiovascular and cerebrovascular and diabetes events in patients with obstructive sleep apnea (OSA). Patients diagnosed with OSA in the sleep center of Tangdu Hospital from January 4, 2011 to December 28, 2016 were retrospectively collected and divided into four groups according to accompanying symptoms: group A included OSA patients without insomnia and excessive daytime sleepiness (EDS), group B included OSA patients with insomnia, group C included OSA patients with EDS and group D included OSA patients with insomnia and EDS. Patients were followed up by telephone for 6 to 11 years. Outcome measures were composite cardiovascular and cerebrovascular and diabetes events (including new onset or recurrent heart disease, cerebral infarction, cerebral hemorrhage, newly diagnosed hypertension and diabetes). Kaplan-Meier method was used to draw survival curves, log-rank test was performed to compare the prognosis of OSA patients with insomnia and/or EDS symptoms, and multivariate Cox proportional hazards model was constructed to analyze the influencing factors of adverse outcome events in OSA patients. Five hundred and four patients with OSA were included, and 307 patients [274 males and 33 females, aged (49±11) years] completed the follow-up, including 27 patients in group A, 143 patients in group B, 27 patients in group C, and 110 patients in group D. After a median follow-up of 7.7 years, 78 patients developed cardiovascular and cerebrovascular and diabetes events. Outcome events occurred in 1 patient (3.70%) in group A, 30 (20.98%) in group B, 10 (37.04%) in group C, and 37 (33.64%) in group D. Compared with patients in group A, there was a statistically significant difference in the incidence of outcome events in groups B (=0.034), C (=0.004), and D (=0.003). After adjusting for age, sex, body mass index, apnea-hypopnea index, baseline cardiovascular and cerebrovascular risk factors and subsequent continuous positive airway pressure therapy, patients in group C (=9.67, 95%: 1.23-76.37, =0.031) and group D (=11.35, 95%: 1.55-83.43, =0.017) had an increased risk of cardiovascular and cerebrovascular and diabetes events when compared with group A. In OSA patients with successful long-term follow-up, insomnia and EDS symptoms are risk factors for the development of cardiovascular and cerebrovascular and diabetes events. Insomnia and EDS symptoms should be evaluated in patients with OSA during clinical practice to find the cause and carry out the targeted intervention.
