北京市1984～1999年急性脑出血和脑血栓发病率变化趋势分析

Trend analyses in the incidence of acute intracerebral hemorrhage events and acute cerebral infarction events in urban areas in Beijing

目的 评估北京市城区人群 1984～ 1999年 16年间脑出血和脑血栓发病率和构成比的变化趋势。方法 在世界卫生组织心血管病趋势及其决定因素监测方案 (WHOMONICA)的北京市城区心血管病人群监测及后续研究中 ,用统一标准化的方法登记年龄在 2 5～ 74岁人群中急性脑出血和脑血栓发病事件 ,逐年计算发病率 ,用世界人口年龄构成计算标化发病率 ,并分析各年龄组发病专率的变化。结果 (1)北京市 1984～ 1999年急性脑出血事件的发病率呈明显下降趋势 ,而急性脑血栓事件的发病率却明显上升 ;(2 )按照MONICA的诊断标准 ,发生急性脑出血占脑卒中的比例由4 2 .0 %降至 16 .0 % ,而发生急性脑血栓的比例由 5 5 .8%上升至 81.6 % ;(3)监测末期和监测初期相比 ,发生急性脑出血和脑血栓事件的年龄发病专率的变化表现不一。结论 脑血栓的发病率和构成比均增加 ,是脑卒中最主要的问题 ,应加强其一级和二级预防。

Objective To study the trends of incidence on acute intracerebral hemorrhage events and acute cerebral infarction events in the population aged 25 74 in urban areas of Beijing from 1984 to 1999. Methods In monitoring the trends and determinants in the cardiovascular disease (MONICA) project and subsequent study, acute intracerebral hemorrhage events and acute cerebral infarction events were registered in a standardized way in men and women aged 25 to 74 years from 1984 1999. Results Both intracerebral hemorrhage attack rates decreased but cerebral infarction attack rates increased significantly; The proportion of intracerebral hemorrhage events in stroke events decreased from 42.0 % to 16.0 % while the proportion of cerebral infarction events in stroke events increased from 55.8 % to 81.6 %, the changes in incidences of acute intracerebral hemorrhage events and acute cerebral infarction events in various age groups were different. Conclusion Cerebral infarction was the most important risk causing stroke, so prevention of cerebral infarction should be strengthened in the area.
