The incidence of sudden coronary deaths verified by autopsy on 1004 males aged 35-64 years in the years 1974-75 in 5 Yorkshire cities or towns was found to be unrelated to the total hardness or magnesium content of the drinking water. However, within a single community (Leeds Metropolitan area) there was a crude inverse relationship between the sudden death risk in the population and the hardness and magnesium content of the drinking water. During the same period there was a generally inverse relationship between both total water hardness and magnesium content and notified deaths from coronary heart disease. The reason for this difference in the distribution of deaths notified as of coronary origin and those proven by autopsy is unknown.
1974年至1975年间，在约克郡的5个城镇对1004名年龄在35至64岁之间的男性进行尸检，结果发现冠状动脉猝死的发生率与饮用水的总硬度或镁含量无关。然而，在单个社区（利兹大都市区），人群中的猝死风险与饮用水的硬度和镁含量之间存在粗略的反比关系。在同一时期，水的总硬度和镁含量与冠心病通报死亡人数之间总体上呈反比关系。冠心病通报死亡人数和尸检证实的死亡人数在分布上存在差异的原因尚不清楚。
