Relationship between cerebral artery stenosis and obstructive sleep apnea / 中华全科医师杂志

ABSTRACT

Objective To investigate the relationship of obstructive sleep apnea and atherosclerotic cerebral artery stenosis.Methods One hundred and twenty patients with acute cerebral infarction were enrolled in the study.Patients underwent polysomnography monitoring;according to the results, the sleep apnea/hypopnea index ( AHI) was ≥5/h in 60 patients ( OSA group) and AHI was 0.05).The rates of increased BMI [(26.07 ±2.39)vs.(23.59 ±2.73) kg/m2] and hypertension [70%(42/60)vs.43%(26/60)] in OSA group were higher than those in non-OSA group (t=5.304,χ2 =7.603, all P0.05 ) . The severity of cerebral artery stenosis in OSA group was higher than that in non-OSA group (χ2 =17.801, P0.05).Conclusion The study indicates that there is a close relationship between OSA and stenosis of atherosclerotic cerebral arteries.
