Objective To investigate the risk factors related to arterial stiffness in patients with obstructive sleep
apnea(OSA) combined with non-dipper hypertension. Methods A total of 264 patients with hypertension admitted to
the geriatrics department of Ruijin hospital, from July 2018 to December 2022 were enrolled. General clinical data and
biochemical indicators were collected, and sleep opnea monitoring, 24-hour ambulatory blood pressure monitoring,
and carotid-femoral pulse wave velocity(c-fPWV) measurements were performed. Patients were grouped based on
ambulatory blood pressure and apnea-hypopnea index(AHI) to study the risk factors for arterial stiffness in patients
with OSA combined with non-dipper hypertension. Result A total of 264 patients with OSA combined with hypertension carotidwere
included, with an average age of(49.88±12.48) years, of which 195 patients had OSA combined with non-dipper
hypertension, accounting for 73.86%. Patients with moderate to severe OSA combined with non-dipper hypertension
were older[(52.33±12.78) years vs. (45.88±11.34) years, P<0.001] and had a faster c-fPWV[(10.19±3.76) m/s vs.
(7.76±1.55) m/s, P<0.001]. The office pulse pressure in patients with moderate to severe OSA combined with
non-dipper hypertension was significantly higher than that in patients with mild OSA combined with non-dipper
hypertension[(57.00±20.00) mmHg vs. (51.00±11.00) mmHg, P=0.031]. The c-fPWV in patients with OSA combined
with non-dipper hypertension was positively correlated with the AHI, 24-hour systolic blood pressure, and office systolic
blood pressure. Logistic regression analysis showed that AHI[odds ratio(OR)=1.03, 95% confidence interval(CI):
1.01—1.06, P<0.05], age(OR=1.14, 95%CI: 1.06—1.12, P<0.05), and office diastolic blood pressure(OR=1.08,
95%CI: 1.01—1.16, P<0.05) were independent risk factors for increased c-fPWV. Conclusion Patients with moderate
to severe OSA combined with non-dipper hypertension exhibit significantly elevated c-fPWV, which is closely associated
with the severity of OSA and blood pressure levels. AHI, age, and office diastolic blood pressure are independent risk
factors for increased c-fPWV. Therefore, patients with OSA combined with non-dipper hypertension, particularly those
with moderate to severe OSA, should focus on early screening and intervention for arterial stiffness to reduce the risk of
cardiovascular events
