Mortality from coronary heart disease has declined for more than 20 years in several industrialized countries. Partly because of a lack of morbidity data, the reasons for the decline are not satisfactorily established. This community-wide survey of coronary heart disease morbidity and mortality in Malmö, Sweden, showed declining mortality rates beginning in the mid-1970s. Between the 3-year intervals 1975-1977 and 1984-1986, coronary heart disease mortality declined by 17% (2,610/100,000 inhabitants in 1984-1986) in men aged greater than or equal to 70 years and by 8% (938/100,000 inhabitants in 1984-1986) in men aged 60-69 years, while coronary heart disease mortality in men aged 50-59 years increased by 7% (355/100,000 inhabitants in 1984-1986). In women aged greater than or equal to 70 years, coronary heart disease mortality decreased by 12% between 1975-1977 and 1984-1986 (1,609/100,000 inhabitants in 1984-1986), while the decrease in women aged 60-69 years was 5% (242/100,000 inhabitants in 1984-1986). The decline in mortality was associated with a decline in both incidence rates and in-hospital case fatality rates for myocardial infarction. The authors suggest that the declining coronary heart disease mortality in Malmö was due partly to prevention of coronary heart disease but that improved medical care for acute and chronic coronary heart disease may also have contributed.
在几个工业化国家，冠心病死亡率已经下降了20多年。部分由于缺乏发病率数据，死亡率下降的原因尚未得到令人满意的确立。这项瑞典马尔默市冠心病发病率和死亡率的社区范围调查显示，自20世纪70年代中期开始死亡率呈下降趋势。在1975 - 1977年和1984 - 1986年这两个三年间隔期内，70岁及以上男性的冠心病死亡率下降了17%（1984 - 1986年为每10万居民2610例），60 - 69岁男性下降了8%（1984 - 1986年为每10万居民938例），而50 - 59岁男性的冠心病死亡率上升了7%（1984 - 1986年为每10万居民355例）。70岁及以上女性的冠心病死亡率在1975 - 1977年至1984 - 1986年间下降了12%（1984 - 1986年为每10万居民1609例），60 - 69岁女性下降了5%（1984 - 1986年为每10万居民242例）。死亡率的下降与心肌梗死发病率和住院病死率的下降相关。作者认为，马尔默市冠心病死亡率下降部分归因于冠心病的预防，但急性和慢性冠心病医疗护理的改善可能也起到了作用。
