Abstract:
Objective:To investigate the impact of obstructive sleep apnea (OSA) on neurological function outcome in patients with acute ischemic stroke (AIS) at 90 days after onset.Methods:Patients with AIS admitted to Hefei Second People's Hospital from September 2022 to June 2023 were prospectively included. According to the modified Rankin Scale score at 90 days after onset, they were divided into a good outcome group (0-2) and a poor outcome group (>2). The demographic data, vascular risk factors, baseline laboratory tests, National Institutes of Health Stroke Scale (NIHSS) scores at admission, severity of obstructive sleep apnea (OSA), and apnea hypopnea index (AHI) were compared between the two groups. Multivariate logistic regression analysis was used to determine the independent risk factors for poor outcomes. Results:A total of 104 patients with AIS were enrolled, including 62 males (59.6%), with a median age of 65.5 years (interquartile range, 57.0-72.0 years). The median baseline NIHSS score was 3.00 (interquartile range, 2.00-4.00). The median AHI was 18.14/h (interquartile range, 11.34-27.88/h), 43 patients (41.35%) with no/mild OSA and 61 patients (58.65%) with moderate to severe OSA. Seventy-four patients (71.2%) had good outcome, and 30 patients (28.8%) had poor outcome. When introducing AHI as a categorical variable into the logistic regression model, the higher baseline NIHSS score (odds ratio [ OR] 3.041, 95% confidence interval [ CI] 1.797-5.145; P<0.001) and moderate to severe OSA ( OR 4.413, 95% CI 1.032-18.877; P=0.045) were independent risk factors for poor outcome; When introducing AHI as a continuous variable into the logistic regression model, higher baseline NIHSS score ( OR 3.176, 95% CI 1.844-5.472; P<0.001), age ( OR 1.093, 95% CI 1.014-1.177; P=0.020), and AHI ( OR 1.044, 95% CI 1.002-1.089; P=0.042) were independent risk factors for poor outcome. Conclusion:Moderate to severe OSA is an independent risk factor for poor functional outcome in patients with AIS at 90 days after onset, and a higher AHI indicates poor outcome in patients.
