Objective: To evaluate prognosis of stroke and identify the risk factors for stroke recurrence.
Methods: Based on the West China Hospital stroke register database, we conducted a prospective follow-up study of stroke patients to record the potential risk factors of stroke recurrence and investigate stroke recurrence at 1 year. Analysis of the risk factors was performed using a logistic regression model.
Results: A total of 1913 stroke consecutive patients admitted to our department were prospectively registered. Of these patients, 599 (31.3%) were identified to have intracerebral hemorrhage (ICH), and 1314 (68.7%) had ischemic stroke. The total recurrence rate at 1 year was 11.2%, and was 10.5% in ischemic patients and 12.7% in ICH patients. Multivariate analysis adjusted for age and gender identified atrial fibrillation, hypertension, hyperlipemia, family history of stroke, and smoking as the risk factors of stroke recurrence at 1 year.
Conclusion: The 1 year recurrent rate is about 11%, and monitoring the factors of atrial fibrillation, hyperlipemia, hypertension, and smoking may help reduce the recurrence of stroke.
