[Trends regarding the incidence of recurrent stroke events in Beijing].
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.


CONCLUSIONS
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.
