目的 了解我国成年人慢性心力衰竭 (心衰 )的患病率和分布特征。方法 中国心血管健康多中心合作研究应用四阶段整群随机抽样方法 ,在全国 1 0个省市 (南方和北方各 5个省市 )抽取具有代表性的样本 ,年龄在 35～ 74岁之间 ,城市和农村各半 ,男、女人数均衡。统计不同年龄组、不同性别和不同地区人群的心衰患病率。结果 共抽样调查 35～ 74岁城乡居民 1 5 51 8人 ,心衰患病率为0 9% ;其中男性为 0 7% ,女性为 1 0 % ,女性患病率高于男性 (P <0 0 5)。 35～ 44岁、45～ 54岁、55～64岁、65～ 74岁年龄组的心衰患病率分别为 0 4%、1 0 %、1 3 %和 1 3 % ;随着年龄增高 ,心衰的患病率显著上升 (P <0 0 1 )。我国北方地区心衰患病率为 1 4% ,南方地区心衰患病率为 0 5 % ,北方明显高于南方 (P <0 0 1 ) ;城市人群心衰患病率为 1 1 % ,农村人群心衰患病率为 0 8% ,城市人群心衰患病率高于农村。结论 心衰正在成为我国心血管病领域的重要公共卫生问题
Objective To understand the prevalence and distribution of chronic heart failure (HF) in adults in China. Methods A multicentre study of cardiovascular health in China was carried out using a four-stage cluster random sampling method. Representative samples were collected from 10 provinces (5 provinces and cities in the south and north China) aged 35-74 years , Urban and rural half, male and female balance. Statistics of different age groups, different gender and different regions of the prevalence of heart failure. Results A total of 15 51 urban and rural residents aged 35-74 years were enrolled in this study. The prevalence rate of heart failure was 0.9%. The prevalence rate was 0 7% in males and 10% in females, and the prevalence was higher in females than in males 0 5). The prevalence rates of heart failure in 35-44 years old, 45-54 years old, 55-64 years old and 65-74 years old group were 0 4%, 10%, 13% and 13% respectively. With age, The prevalence of heart failure increased significantly (P <0.01). The prevalence of heart failure in the north of China was 14%, that of the heart failure in the south was 05%, significantly higher in the north than in the south (P <0.01), and that of the urban population was 11% The prevalence of heart failure in rural population was 0.8%, and the prevalence of heart failure in urban population was higher than that in rural areas. Conclusion Heart failure is becoming an important public health issue in the field of cardiovascular disease in our country
