Crawford等曾提出在事故死亡的尸检中,英国格拉斯哥软水地区居民男性青年冠状动脉中的镁含量低于硬水地区伦敦男性青年居民的;40岁以上的人则无此差别,但这一年龄的格拉斯哥的男性有更多的动脉粥样化,在动脉表面有镁和钙的沉积。这样的矛盾在心肌中是不存在的。根据另两个研究,心肌中的镁浓度在死于心肌梗塞的人中有比死于其它死因者低的倾向。Chipporfield提出,软水地区居民心肌的镁含量低于硬水地区的居民。作者在加拿大就死于事故的64名男性做了研究,其中20名是三个不同的硬水(总硬度342～516 ppm)地区居民,44个是五个软水(硬度为53 ppm或以下)地区居民。心
Crawford et al. Proposed that in the autopsy at the accidental death, magnesium content was lower in young male coronary arteries in residents of Glasgow soft-shelled areas than in young London-based men in hard-water areas; no difference was found in those over the age of 40, but Glasgow, Of men have more atherosclerosis with deposition of magnesium and calcium on the surface of the artery. This contradiction does not exist in the myocardium. According to two other studies, the magnesium concentration in myocardium tended to be lower among those who died of myocardial infarction than those who died of other causes of death. Chipporfield proposed that the magnesium content in the heart muscle of soft water areas is lower than that of hard water areas. The authors studied 64 men who died in an accident in Canada, of which 20 were residents of three different hard water (total hardness 342 to 516 ppm) and 44 were five softened water (53 ppm or less) Residents. heart
