BACKGROUND: Data concerning stroke occurrence and recurrence in China are extremely rare. This study was designed to analyze determinants of stroke recurrence in a cohort of Chinese patients. METHODS: Subjects were patients with ischemic stroke registered in the Nanjing Stroke Registry Program. Modifiable risk factors for stroke were identified and stratified into 3 levels: without, controlled and uncontrolled. Cox proportional hazard model was used to detect influence factors for stroke recurrence. RESULTS: First-year recurrence rate was 11.2% in the registered patients. Hypertension, atrial fibrillation (AF) and smoking were associated with increased risk of recurrence. Controlling hypertension and AF each halved recurrent risk (p < 0.001). Ceasing smoking for more than 1 year reduced hazard ratio of recurrence from 1.71 to 1.39 (p < 0.05). Controlling blood sugar level in diabetics did not significantly change recurrent risk (hazard ratio, 1.69 vs. 1.64, p > 0.05). CONCLUSIONS: The recurrence rate is higher in Chinese patients with ischemic stroke compared with the one reported in western populations. Failure to control some modifiable risk factors in Chinese patients may be responsible for this discrepancy.
