| Objective To explore the clinical characteristics of patients with and without sleep disorders after stroke, and analyze the correlation between their clinical characteristics and the risk of stroke recurrence, in order to provide reference for clinical prevention and treatment. Methods A total of 246 patients with post-stroke sleep disorders from September 2021 to July 2023 were selected as the sleep disorder group, and 230 patients without sleep disorders after stroke were selected as the non-sleep disorder group. The clinical characteristics and stroke recurrence rates of the two groups were compared, and the stroke recurrence risk of patients with different clinical characteristics in the sleep disorder group was compared. Results There were significant differences in age, sex, hypertension, diabetes, hyperlipidemia, drinking history, habitual snoring, stroke type, stroke site, and degree of neurological impairment between the two groups (P<0.05); following up for six months, the recurrence rate of stroke in patients with post-stroke sleep disorders was 24.80% (61/246), which was higher than that in patients without post-stroke sleep disorders at 6.96% (16/230)（ χ2=27.900, P<0.05); According to the hypothesis test of RR, there was a statistically significant difference in the risk of stroke recurrence between patients with post-stroke sleep disorders and those without post-stroke sleep disorders (U=4.836, P<0.05); there was a statistically significant difference in the proportion of recurrent and non recurrent patients with sleep disorders, including age, history of chronic diseases, history of chronic diseases, history of alcohol consumption, habitual snoring, stroke type, stroke site, and degree of neurological deficits (P<0.05); contingent correlation analysis showed that age, drinking history, habitual snoring, hypertension, diabetes, hyperlipidemia, ischemic stroke, basal ganglia stroke were positively correlated with the risk of stroke recurrence (P<0.05); Spearman correlation analysis showed that the degree of neurological deficits was positively correlated with the risk of stroke recurrence (P<0.05). Conclusion Post stroke sleep disorder is positively correlated with the risk of stroke recurrence. Age, drinking history, habitual snoring, hypertension, diabetes, hyperlipidemia, ischemic stroke, basal ganglia stroke, and degree of neurological impairment are positively correlated with the risk of stroke recurrence. Clinical treatment should be based on the characteristics of sleep disorder and formulate corresponding prevention and treatment programs to reduce the risk of stroke recurrence. |
