Initial screening of acute cerebrovascular infarction patients complicated sleep apnea hypopnea syndrome(SAHS)

Objective To research the condition that acute cerebrovascular infarction patients suffered from sleep apnea hypopnea syndrome(SAHS).Methods 200 patients with acute cerebrovascular infarction from January 2008 to December 2008 hospitalize in our department were primarily screened,of them 40 patients who could admire and cooperate were undergoing polysomnography(PSG);patients with acute cerebrovascular infarction at the same time and not suffered from SAHS according to EWW lethargy self-scale were randomly selected.Patients'age,body weight index(BMI),history of sleep snore,hypertension,diabetes,smoking,apnea hypopnea index(AHI),lowest artery blood oxygen solution(SaO2)and the location,symptom of infarction were compared.Results It was 20% that acute cerebrovascular infarction patients with SAHS,of them,obstructive and mixed pattern were majority in sleep apnea syndrome;The group age from 45 to 60 years old suffered the most,the proportion was 60%;the patients whose AHI20 were 70%;the patients with SAHS whose disease located in brain stem and with swallow difficulty,drink cough symptoms were more severe.Conclusion The patients with balloon paralysis accompany with SAHS are more severe conditions.Sleep apnea hypopnea syndrome is an indispensable risk factor of cerebrovascular infarction.BMI and abnormal function of surrounding tissues of upper airway is an important factor to cause obstructive sleep apnea hypopnea syndrome.
