The study identified predictors of unfavorable outcomes and stroke recurrence in young Chinese patients with ischemic stroke, with high NIHSS score and severe vascular stenosis as independent predictors of poor prognosis, and age and atrial fibrillation as predictors of recurrence.
Objective To identify predictors of young Chinese patients with ischaemic stroke outcome and recurrence of stroke. Design Through considered the risk factors, neuroimaging findings, distribution, vascular stenosis, and the post-stroke treatment of young Chinese patients with ischemic stroke. Setting The First Hospital of Jilin University. Participants We enrolled 579 patients (median age 45 years, range 15-49, men 81.0%) treated for the first occurrence of ischaemic stroke between January 2014 and December 2017. Main outcome measures We assessed stroke outcome based on the modified Rankin Scale (mRS) scores and recurrence of cerebrovascular events at 12 months. Multivariate logistic regression was used to identify the independent predictors of unfavourable outcomes (mRS score >= 2) and recurrence. Results We observed stenosis in 295 patients (50.9%)-middle cerebral artery stenosis was the most common (18.1%). Of all 579 included patients, normal or mild, moderate and severe stenoses or occlusions were observed in 51.8%, 6.0% and 42.1% of patients, respectively. Unfavourable outcomes were observed in 91 patients (15.7%), including 10 patients (1.7%) who died. The rate of stroke recurrence was 7.9%. Independent predictors of unfavourable outcomes included a high National Institutes of Health Stroke Scale score (OR 1.151, 95% CI 1.094 to 1.210; p<0.001) and severe vascular stenosis or occlusion (OR 1.867, 95% CI 1.181 to 2.952; p=0.008). Predictors of recurrence included age of >= 45 years (OR 2.072, 95% CI 1.066 to 4.025; p=0.032) and atrial fibrillation (OR 15.207, 95% CI 4.273 to 54.120; p<0.001). Conclusions Our research shows that when developing prevention strategies for young people, measures that focus on mitigating risk factors should be considered. In addition, vascular screening of young populations is also of vital importance for stroke prevention and poor prognosis prediction.
