Trends in mortality from Ischemic Heart Disease (IHD) and other principal causes of death, and in hospital admission rates for Acute Myocardial Infarction (AMI) have been studied in residents aged 35-64 years of the Perth Statistical Division for the period 1968-1982. Death rates were based on data abstracted from official statistics or computer tapes of unit death records. Hospital admission rates were derived from the computer tapes of the Western Australian Hospital Inpatient Survey, 1968-1982. Since 1968, mortality from IHD has fallen in the Perth Statistical Division in both males and females by 30% and 33%, respectively. This fall has occurred principally in deaths occurring out-of-hospital and has been accompanied by similar falls in mortality from other vascular diseases and in total mortality. Hospital admission rates for Acute Myocardial Infarction (AMI) in the Perth Statistical Division have fallen since 1971 by 17% in males and 27% in females. These findings taken together suggest that the improvement in IHD mortality in Western Australia has been due mainly to a fall in the incidence of acute manifestations of IHD (sudden death and AMI), rather than improvements in case fatality. The possible underlying mechanisms responsible for this are discussed.
对珀斯统计分区35至64岁居民在1968年至1982年期间因缺血性心脏病（IHD）和其他主要死因导致的死亡率趋势，以及急性心肌梗死（AMI）的住院率趋势进行了研究。死亡率基于从官方统计数据或单位死亡记录的计算机磁带中提取的数据。住院率来自1968年至1982年西澳大利亚医院住院患者调查的计算机磁带。自1968年以来，珀斯统计分区中IHD导致的死亡率在男性和女性中分别下降了30%和33%。这种下降主要发生在院外死亡中，同时其他血管疾病的死亡率和总死亡率也出现了类似下降。自1971年以来，珀斯统计分区中急性心肌梗死（AMI）的住院率在男性中下降了17%，在女性中下降了27%。综合这些发现表明，西澳大利亚IHD死亡率的改善主要是由于IHD急性表现（猝死和AMI）的发病率下降，而非病例死亡率的改善。文中讨论了可能导致这种情况的潜在机制。
