Introduction: Stroke is a potentially disabling event, therefore determining its etiology is the key in the development of management strategies to reduce the risk of a new event and costs. Obstructive sleep apnea (OSA) is common in stroke and is an independent risk factor. The objective of this study was to determine the association between the etiology of ischemic stroke and the presence of OSA. Methods: Observational, descriptive, patients with ischemic stroke or acute transient ischemic attack (TIA) in the Hospital Memorial São José and Hospital Esperança Recife-PE for one year, the etiology of stroke was categorized by TOAST classification and portable polysomnography for diagnosis of OSA. Results: 100 patients analyzed, 81 ischemic strokes and 19 TIA. The prevalence OSA (AHI≥15) was 51%. The mean age of the sample was 67.9±14.6 years, with older OSA patients (70.0±14.2 vs 65.6±14.7, p=0.128). There was a higher occurrence of females, DM, dyslipidemia and previous ictus in patients with OSA (p=0.052 /0.008 /0.055 /0.018, respectively). BMI was 27.22±4.3kg/m² in patients without OSA and 28.05±3.8kg/m² among patients with OSA. There was no association between the etiological subtype of ictus and the presence of OSA (p=0.698). Conclusions: Our study included an elderly population with a higher frequency of dyslipidemia, DM and previous ictus in patients with OSA, but it was not possible to establish a relationship between the etiology of the stroke and the presence of OSA.
