Letter: Ischemic heart disease, water hardness and myocardial magnesium. (1/17)

In 54 cases of accidental death in cities with water hardness of 60 parts per million (ppm) or less, the mean myocardial magnesium concentration was 918 mug/g of dry tissue. This was 7% lower than the corresponding figure of 982 mug/g among 29 cases of accidental death in cities with water hardness of 300 ppm or more, and this difference was significant (P less than 0.01). There were no significant differences between the cities with soft and hard water in the mean myocardial concentrations of calcium, zinc, copper, chromium, lead or cadmium. These results are compatible with the belief that the relatively high death rates in some soft-water areas may be due to a suboptimal intake of magnesium, and that water-borne magnesium exerts a protective effect on the residents of hard-water areas.  (+info)

Myocardial infarction and water hardness in the WHO myocardial infarction registry network. (7/17)

The negative association between water hardness and cardiovascular disease found by several authors in different countries has also been found in the present investigation. All cases of myocardial infarction were registered in a standardized way at 15 WHO Collaborating Centres in Europe; information on the hardness of drinking water used by the population studied was also collected. Higher rates of myocardial infarction were usually found in towns served by softer water.  (+info)
