[Study on the relationship between hypertension management and the risk of stroke at community level].
OBJECTIVE
To observe whether the community-based management for patients with hypertension can reduce the incidence of stroke.


METHODS
Sample of this study included 36 863 people aged 35 years or more who came from a cohort consisting three communities from Tiantan Hospital, Puren Hospital and the Gymnasium Road Hospital in Beijing, based on the surveys on the Integrated Community Intervention Measures of Cerebro-vascular Diseases. Some patients with hypertension in this cohort were followed up and under management. First-ever stroke was considered as the end-point event.


RESULTS
In both groups diagnosed as borderline hypertension or definite hypertension group, the rates of management and control showed an annual increase. The management rate for women was higher, but the control rate was lower (P < 0.05) than that for men. In the third year of this study, the control rate was nearly 18%. With the qualification of control rate, the risk factors of overall stroke, ischemic stroke or hemorrhagic stroke reduced gradually, and the qualification of control rate showed more effects on hemorrhagic stroke. The qualification of control rate in the three years could cause the risk factors of total stroke, ischemic stroke or hemorrhagic stroke to reduce by 25.7%, 19.1%, 27.4%, respectively. When comparing with blood pressure level at < 160/95 mm Hg (1 mm Hg = 0.133 kPa), the level of < 140/90 mm Hg could reduce the risk factors as: 12.3% to total stroke, 12.8% to ischemic stroke and 14.9% to hemorrhagic stroke.


CONCLUSIONS
Programs as long-term followed-up and management for patients with hypertension, and control the blood pressure at low level etc. could significantly reduce the incidence of stroke.
