Objective: the author aimed to determine the cumulative recurrence rates at 30 days, 90 days and one year respectively after acute ischemic stroke. Method: This was a prospective observational cohort study. To meet the objective of the research, the Kaplan-Meier estimator and Cox proportional hazards models were used to assess the cumulative recurrence rates after acute ischemic stroke and the difference among ischemic stroke subtype groups. Results: 405 patients with acute ischemic stroke were included in the study from 2010 to 2012. The mean follow-up period was 363.29 days. The cumulative rates of stroke recurrence at 30 days, 90 days and 1 year after acute ischemic stroke were 6 percent, 11.88 percent and 23.29 percent respectively. The rates of stroke recurrence were significantly different among ischemic stroke subtype groups: the cardioembolic group was the highest and the lacunar infarction was the lowest (p = 0.000). Conclusion: The cumulative rate of stroke recurrence in the first year after acute ischemic stroke was high. The rates of stroke recurrence were significantly different among ischemic stroke subtype groups.
