Abstract

Background and objectives: Sleep-disordered breathing (SDB) is characterized by pauses or shallow breathing during sleep. It is linked to poorer outcomes and increased stroke recurrence in stroke patients. We aimed to evaluate the proportion, severity, type, and evolution of SDB and arousals in ischemic stroke patients.

Methods: Ischemic stroke patients were recruited to evaluate SDB. Patients underwent overnight polysomnography (PSG) twice - within 1 month of stroke onset and again after 3 months. Clinical outcomes were evaluated at 6, 18, and 24 months.

Results: Of 141 acute ischemic stroke patients screened, 111 patients recruited in the study and 105 patients had technically adequate polysomnography. The mean age of patients was 50.5 years (standard deviation [SD]: 12.30), 78.4% of the patients were males, and the mean body mass index was 26 (SD: 5.4). Results showed that 81.9% had an apnea-hypopnea index (AHI) ≥5, with 12.5% having an AHI >30. The median arousal index (ArI) was 15.4 (interquartile range [IQR]: 0.5-50.5), which increased as the apnea increased. During follow-up, 56.8% patients had an AHI ≥5, with 12.5% having severe apnea. The median ArI decreased from 15.4 (IQR: 0.5-50.5) initially to 11.54 (IQR: 0.5-21.1) at follow-up. Numerical change in AHI severity categories were noted during the follow-up (mild: 8 vs 15; moderate: 17 vs 11; severe 19vs 7). For AHI >30, ArI decreased from 24.63 (IQR: 0.7-50.05) to 10.54 (IQR: 7.1-15.07) at follow-up. Sleep efficiency and rapid eye movement (REM) sleep duration increased on follow-up.

Conclusions: The study showed a high proportion of SDB in acute ischemic stroke patients. In the follow-up, SDB improved, as reflected in AHI and ArI changes.

期刊介绍: The journal has a clinical foundation and has been utilized most by clinical neurologists for improving the practice of neurology. While the focus is on neurology in India, the journal publishes manuscripts of high value from all parts of the world. Journal publishes reviews of various types, original articles, short communications, interesting images and case reports. The journal respects the scientific submission of its authors and believes in following an expeditious double-blind peer review process and endeavors to complete the review process within scheduled time frame. A significant effort from the author and the journal perhaps enables to strike an equilibrium to meet the professional expectations of the peers in the world of scientific publication. AIAN believes in safeguarding the privacy rights of human subjects. In order to comply with it, the journal instructs all authors when uploading the manuscript to also add the ethical clearance (human/animals)/ informed consent of subject in the manuscript. This applies to the study/case report that involves animal/human subjects/human specimens e.g. extracted tooth part/soft tissue for biopsy/in vitro analysis.
