西方国家冠心病(CHD)死亡率在过去的40年里显著降低,但是最近来自亚特兰大艾莫瑞大学医学院的研究人员发现,美国自1979年以来,CHD死亡率大幅下降背后存在巨大的差异。该研究近日发表在Circulation杂志上。研究人员对1979年~2011年间,年龄处于25及25岁以上的美国成人进行了分析,并计算出了不同年龄段CHD的死亡率,比较了3个阶段:1979~1989、1990~1999、 Death rates from coronary heart disease (CHD) in Western countries have dropped significantly over the past 40 years, but researchers from the Emory University School of Medicine in Atlanta recently found that there have been huge differences in the dramatic decline in CHD mortality in the United States since 1979. The study recently published in Circulation magazine. The researchers analyzed American adults aged 25 and over from 1979 to 2011, and calculated the mortality of CHD at different ages, compared with three stages: 1979 ~ 1989, 1990 ~ 1999,
