Investigation of symptoms and risk factors of obstructive sleep apnea among patients with acute stroke who were hospitalized in Alzahra hospital, Isfahan, Iran, during 2014

Abstract

Background: Obstructive sleep apnea and stroke are the most common diseases worldwide and especially in our country. Previous studies showed that both above diseases are common risk factors and in some of study co-morbidity to stroke and obstructive sleep apnea were reported. Thus, considering the high prevalence of stroke and obstructive sleep apnea, the aim of this study was to determine the symptoms and risk factors of obstructive sleep apnea among patients with acute stroke who were hospitalized in Alzahra hospital, Isfahan, Iran during 2014. Methods: In a case control study, 55 stroke patients and 55 healthy persons were studied for obstructive sleep apnea. Sleepiness symptoms and risk factors of obstructive sleep apnea was measured by special checklist and comparison between the two groups was done by SPSS software. Findings: The mean of obstructive sleep apnea in case and control groups was 9.6 ± 2.9 and 6.5 ± 4.9 respectively and a significant difference between the two groups was seen (P < 0.001). the mean of total number of risk factors of obstructive sleep apnea in the two groups was 9.5 ± 2.9 and 6.4 ± 4.8 respectively (P < 0.001). 29(52.7) of case group and 11(20) of control group had at least 10 numbers of obstructive sleep apnea symptoms and the difference between the two groups was significant (P < 0.001. Conclusion: Notice to high prevalence and importance of obstructive sleep apnea and stroke and common risk factors of the two disease and noting the lack of studies about co-morbidity of obstructive sleep apnea and stroke, more study about the relation between stoke and obstructive sleep apnea was needed, also patients with obstructive sleep apnea mast identify and treatment and prevention programs must be done for these patients. © 2016, Isfahan University of Medical Sciences(IUMS).
