BACKGROUND: Recurrent stroke is one of severe outcomes of transient ischemic attack (TIA) and minor ischemic stroke (MIS), which are collectively termed as nondisabling stroke. However, the association between multiple risk factors and nondisabling stroke has not been fully studied. Here, we aimed to identify predicative risk factors in TIA and MIS in order to prevent recurrent nondisabling stroke.
METHODS: We used logistic regression methods to analysis risk factors in 620 patients with TIA or MIS between August 2006 and january 2009 and followed up to 90 days. We selected 20 factors, including age, gender, body mass index (BMI), smoking and alcohol history, blood pressure, limb weakness, speech impairment, diabetes, ischemic brain lesions, previous history of stroke (> 24 hours), coronary atherosclerotic heart disease, cardiac function insufficiency, duration of symptoms of at least 1 hour, blood lipids, lysophosphatidic acid, C-reactive protein, atrial fibrillation, and carotid artery plaque in ultrasound examination.
RESULTS: We found that limb weakness, history of cerebrovascular events, and carotid artery plaque in ultrasound examination were risk factors of recurrent stroke within 14 days, whereas the factors for the recurrence within 90 days were duration of symptoms of at least 1 hour, speech impairment, limb weakness, BMI of at least 25 kg/m2, history of cerebrovascular events, and carotid artery plaque in ultrasound examination.
CONCLUSION: Six risk factors are associated with recurrent nondisabling stroke, including symptom duration of at least 1 hour, speech impairment, limb weakness, BMI of at least 25 kg/m2, history of cerebrovascular events, and carotid artery plaque in ultrasound examination. Thus, identification and prevention of these risk factors may reduce recurrent stroke.
