To describe the clinical features of sleep apnea syndrome in stroke patients. Methods: A descriptive study of 29 stroke patients with sleep apnea syndrome at Bach Mai hospital from August 2021 to August 2022. Results: The male group consisted of 24 people (82.76%), the mean age was 68.33± 9.67. The female group consisted of 5 people (17.24%), average age: 69.2±7.66. There was no difference in mean age between the two sexes (p=0.52). Of the 29 patients, 2 were normal weight, 7 were overweight, and 20 were obese. Neck circumference ≥40 cm was seen in 20 patients. Hypertension is the most common comorbidity, accounting for 82.76%. In 29 patients, mild sleep apnea was 10 patients, average was 8 patients, severe was 12 patients. Snoring was the most common clinical symptom in the study group (26 patients, accounting for 89.66%). There was no difference in systolic and diastolic blood pressure between levels of sleep apnea. In 29 patients, there were 19 patients with mild stroke, and 10 patients with moderate stroke. There was no difference in NIHSS scores between levels of sleep apnea. Conclusion: We highly recommend screening patients at high risk for sleep apnea such as high BMI, diabetes, history of frequent loud-irregular snoring, and observed apneas.
