Intravenous magnesium has been found to reduce early death from heart attacks.
According to research carried out at the Coronary Care Unit of Leicester Royal Infirmary of 2316 patients with suspected heart attacks, a slow transfusion of magnesium sulphate reduced deaths by nearly a quarter.
Magnesium also lessened the incidence of left ventricular (lower heart chamber) failure by 25 per cent.
The researchers concluded that this means of delivering magnesium to patients would save the lives of 25 of every 1000 heart attack patients. Nevertheless, they caution that magnesium to treat heart attacks cannot be taken orally because the level required is so high that it would damage the intestines if allowed to pass through the digestive system.
