Background: The incidence of recurrent stroke and mortality ratio of patients with a transient ischemic attack (TIA) and minor ischemic stroke (MIS) is a challenging issue, especially the long-term recurrence ratio.
Aims: This study aimed to estimate the long-term incidence of ischemic stroke recurrence and identify the risk factors associated with recurrent stroke in the Xuzhou region of China.
Settings and design: This was a cross-sectional study conducted on a group of patients with TIA or MIS between the ages of 20 and 80 years.
Methods and material: A total of 297 individuals participated. Medical records were one of the data sources. The data of patients who meet the selection criteria gathered from the Neurology department, affiliated hospital of Xuzhou medical university Statistical analysis used: Statistical package for Social Science (SPSS) version 23 was used for statistical analysis.
Results: In this study, 297 patients were included for analysis; 30 (9.17%) patients were lost to follow-up at 5 years. Post onset of the TIA and MIS analysis reveals that the cumulative incidences of recurrent stroke at 3,6,12, 36, and 60 months were 6.73% (20/297), 10.77% (32/297), 18.86% (56/297), 25.25% (75/297), and 33.33% (99/297), respectively. Multivariate regression analysis demonstrated that age, current smoking, poorly controlled hypertension, diabetes, vascular stenosis, and plaque vulnerability as independent risk factors for ischemic stroke recurrence. Further analysis based on different vascular stratification of carotid atherosclerosis showed that 5-year cumulative survival was 10% lower in patients with severe stenosis than in patients with plaque vulnerability.
Conclusion: This study aimed to estimate the long-term incidence of ischemic stroke recurrence and identify the risk factors associated with recurrent stroke in the Xuzhou region of China.
