Trends in ischemic heart disease mortality are of current interest because death rates have declined rapidly in the United States, Australia, and some other countries during the last decade, although they have risen elsewhere. There is a need to assess the quality of the data from which such trends are calculated and to consider what information will be required to monitor accurately future patterns of incidence and mortality for this disease. This paper describes two investigations of routinely collected mortality data for ischemic heart disease in Australia. First, information obtained from a heart attack surveillance study was compared with officially recorded causes of death for a defined population during 1979. Second, mortality trends from 1969 to 1978 were compared between the major Australian states. Both studies showed that mortality data were accurate to within about 10%. However, for acute myocardial infarction and other subcategories of ischemic heart disease, the data were neither valid nor reliable. New diagnostic and coding practices are required before it will be possible to monitor accurately long-term trends in subcategories of ischemic heart disease.
缺血性心脏病死亡率的趋势是当前人们关注的焦点，因为在过去十年中，美国、澳大利亚和其他一些国家的死亡率迅速下降，尽管在其他地方有所上升。有必要评估用于计算此类趋势的数据质量，并考虑监测该疾病未来发病率和死亡率模式所需的信息。本文描述了对澳大利亚缺血性心脏病常规收集的死亡率数据的两项调查。首先，将从心脏病发作监测研究中获得的信息与1979年特定人群的官方记录死因进行了比较。其次，比较了澳大利亚主要州1969年至1978年的死亡率趋势。两项研究均表明，死亡率数据的准确率在10%左右。然而，对于急性心肌梗死和缺血性心脏病的其他子类别，数据既无效也不可靠。在能够准确监测缺血性心脏病子类别长期趋势之前，需要新的诊断和编码方法。
