2007至2009年北京市25岁以上居民急性冠心病事件发病率的监测

Surveillance on the incidence of acute coronary events in the permanent residents of Beijing aged 25 years and more from 2007 to 2009

目的监测2007至2009年北京市25岁以上居民急性冠心病事件发病率及其变动趋势，探讨其在不同特征人群中的特点。方法整合北京市公共卫生信息中心的北京市出院病人信息系统和北京市疾病预防控制中心的北京市死因登记报告信息系统的常规医疗信息数据，统计北京市25岁以上居民急性冠心病事件发病率，分析其在不同性别、年龄以及地区间分布的差异。急性冠心病事件包括非致死性急性心肌梗死和冠心病死亡。2007至2009年北京市户籍人口的数据来源于北京市统计局。结果2007至2009年，北京市居民25岁以上居民发生急性冠心病事件共68390例，年龄标化发病率总体为166．4／10万，男性为218．5／10万，女性为115．2／10万，城区为144．3／10万，近郊为154．7／10万，远郊为195．8／10万。年龄标化发病率怀柔区最高，为263．8／10万；海淀区最低，为121．5／10万。2007至2009年的年龄标化发病率分别为158．4／10万、169．4／10万和171．2／10万，2009年比2007年上升了8．1％。与2007年比较，2009年男性和女性居民的年龄标化发病率分别增加了11．1％和2．5％。各年度急性冠心病事件发病率均随年龄的增大而增加。男性35～44岁人群急性冠心病事件发病率的增幅最大，2009年比2007年增加了30．3％。2009年北京市城区、近郊和远郊急性冠心病事件的发病率分别为146．7／10万、155．9／10万和207．4／10万，与2007年相比城区和近郊均增加了3．2％，远郊增加了16．4％。结论2007至2009年，北京市25岁以上居民急性冠心病事件发病率逐年上升，其中男性、年轻和远郊人群的发病率上升较快。

Objective To survey the incidence of acute coronary events and its trend in three years, and explore the distribution of the incidence across Beijing residents aged 25 years and more from 2007 to 2009. Methods The present study incorporated and linked the routinely collected data from the Hospital Discharge Information System and Cause of Death Register System in Beijing, estimated the incidence of acute coronary events, and analyzed the distribution of the incidence across gender, age groups and regions. Acute coronary event was defined as non-fatal myocardial infarction and death from coronary heart disease. Numbers of residents by age, gender and area were obtained from the Beijing Statistics Bureau. Results A total of 68 390 acute coronary events were identified among permanent residents of Beijing aged 25 years and more from 2007 to 2009. The age-standardized incidence was 166. 4 per 100 000 people in overall population, with 218.5 in males and 115.2 in females. The age-standardized incidence was 144. 3, 154. 7, and 195.8 per 100 000 people in urban, suburban, and exurban area, respectively. The incidence was the highest in Huairou district （263.8 per 100 000） , while was the lowest in Haidian district（ 121.5 per 100 000）. The age-standardized incidence was 158.4, 169.4, and 171.2 per 100 000 in 2007, 2008, and 2009, respectively. The age-standardized incidence increased by 8.1% in 2009 compared to 2007, increase in men （ 11.1% ） was greater than in women （2. 5% ）. The incidence increased significantly with age in each year. The incidence raised by 30. 3% in 2009 compared to 2007 for men aged 35 - 44 years. In 2009, the incidence was 146. 7, 155.9, and 207.4 per 100 000 people in urban, suburban, and exurban area, respectively. The rates increased by 3.2% in both urban and suburban areas, and 16.4% in exurban areas in 2009 compared to 2007. Conclusion The incidence of acute coronary events increased from 2007 to 2009 among the permanent residents of Beijing aged 25 years and over, especially in young men, and people living in the exurban areas.
