In Australia, mortality rates from ischemic heart disease have declined by more than 40 per cent in the last 20 years. To investigate the reasons for this trend, detailed studies are being conducted in the Hunter Region of New South Wales, an area with high heart disease rates. Data on death rates and attack rates from 1979 to 1984-1985 were obtained from three sources: national mortality records, local hospital statistics, and heart disease registers conducted in 1979 and 1984-1985 using World Health Organization protocols. Age-standardized death rates from ischemic heart disease, hospitalization rates for acute myocardial infarction, and attack rates from myocardial infarction determined from the disease registers all showed declines of approximately 3-4 per cent per year from 1979 to 1985. The results differ from findings in New Zealand, where the decrease in ischemic heart disease mortality has been attributed to fewer sudden deaths. These discrepancies demonstrate the need for carefully standardized studies to gain insight into evolving patterns of heart disease in different populations.
在澳大利亚，过去20年里缺血性心脏病的死亡率下降了40%以上。为了探究这一趋势的原因，正在新南威尔士州的猎人地区开展详细研究，该地区心脏病发病率较高。1979年至1984 - 1985年的死亡率和发病率数据来自三个来源：国家死亡率记录、当地医院统计数据，以及1979年和1984 - 1985年按照世界卫生组织规程进行的心脏病登记。从疾病登记中确定的缺血性心脏病年龄标准化死亡率、急性心肌梗死住院率以及心肌梗死发病率在1979年至1985年期间均显示每年下降约3 - 4%。这些结果与新西兰的研究结果不同，在新西兰，缺血性心脏病死亡率的下降归因于猝死病例减少。这些差异表明需要进行仔细标准化的研究，以深入了解不同人群中心脏病的演变模式。
