A comparison of mortality from ischaemic heart disease under the age of 60 for 1980 to 1981 between the Grampian Health Board and the North Staffordshire Health Authority has been made. A total of 993 deaths was notified by death certificate from the two areas of similar population of which 434 were from Grampian and 559 from North Staffordshire. After examination of general practitioner and hospital case notes, autopsy reports and death certificates, nearly all (532) of the North Staffordshire deaths were accepted as being due to ischaemic heart disease but only three-fifths (263) of the Grampian deaths could be substantiated as there was inadequate information for the remainder. Deaths from ischaemic heart disease seem apparently to be twofold greater in North Staffordshire than Grampian but much of this discrepancy could be attributed to a widely different autopsy rate and to unavailability of case notes. Experience of this survey suggests that the results of other epidemiological investigations may be equally or even more unreliable.
对格兰扁健康委员会和北斯塔福德郡卫生局辖区内1980年至1981年60岁以下人群缺血性心脏病死亡率进行了比较。两个地区人口规模相近，共通过死亡证明通报了993例死亡病例，其中434例来自格兰扁，559例来自北斯塔福德郡。在检查了全科医生和医院病历、尸检报告及死亡证明后，北斯塔福德郡几乎所有（532例）死亡病例都被确认为死于缺血性心脏病，但格兰扁只有五分之三（263例）死亡病例能够得到证实，其余病例信息不足。北斯塔福德郡缺血性心脏病死亡率似乎明显是格兰扁的两倍，但这种差异很大程度上可归因于尸检率差异巨大以及病历难以获取。本次调查的经验表明，其他流行病学调查结果可能同样不可靠甚至更不可靠。
