Objective: To explore the trends and distributions of incidence on recurrent stroke events in population aged 35 to 74 in Beijing from 1984 to 2000.
Methods: In Sino-MONICA project, acute stroke events were registered in a standardized way in men and women aged 35-74 years in Beijing from 1984-2000. Recurrent stroke event was defined as recurrence within 28 days after first stroke onset.
Results: From 1984 to 2000, incidence of recurrence stroke events increased from 89.51/100 000 to 143.34/ 100 000. In the 17 years of follow-up period, rate of recurrent ischemic stroke increased by 153%, and the rate of hemorrhagic stroke decreased by 42.94%. In all events, the recurrent rate of stroke accounted for 29.8%. This rate was higher in men (31.7%) than that in women (26.9%). The event rate of recurrent stroke 1.6% of increase per year in men, higher than that in women which was 0.6%. Subjects with history of hypertension, diabetes, coronary heart disease had a higher rate of recurrent stroke.
Conclusion: Recurrence rates for stroke events increased significantly during the 17 years of observation, from 1984 to 2000. Subjects with history of hypertension, diabetes and coronary heart disease had a higher rate of recurrent stroke than other subjects.
