Distribution of risk factors of ischemic stroke in Chinese young adults and its correlation with prognosis

BACKGROUND: The risk factors for ischemic stroke in young people are complex, varied and closely related to prognosis. This study aims to analyze the risk factors for ischemic stroke in Chinese young people and to explore the main factors influencing the prognosis. METHOD: A total of 444 patients aged 16 to 45 years with ischemic stroke admitted to Suzhou tertiary hospital from 2011 to 2019 were retrospectively analyzed. Risk factors were identified according to the IPSS definition of pediatric stroke and the TOAST classification. All patients were followed up, and the modified Rankin score was used to evaluate the prognosis. Logistic regression analysis was used to explore the influencing factors of poor prognosis. RESULTS: Among the patients, 12 risk factors were found according to the IPSS definition of pediatric stroke, and 5 types of stroke were found according to the TOAST classification. A total of 299 patients had a good prognosis. Anemia, venous sinus thrombosis, isolated large-vessel occlusion, and high baseline NIHSS score were significant risk factors. CONCLUSION: The IPSS definition enables patients to be classified on the basis of more risk factors than other classification methods. The prognosis of ischemic stroke in young people is generally good in the 5 years following the event. Anemia, venous sinus thrombosis, isolated large-vessel occlusion and high baseline NIHSS score were associated with poor prognosis.
