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.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
