Researchers examined the association between magnesium, as measured in diet and plasma, and risk of Sudden Cardiac Death Syndrome. The analysis, which appeared in the American Journal of Clinical Nutrition, was conducted within the Nurses' Health Study. The association for magnesium intake was examined prospectively in 88,375 women who were free of disease in 1980. 505 cases of sudden or arrhythmic death were documented over 26 y of follow-up. The relative risk of SCD was significantly lower in women in the highest quartile compared with those in the lowest quartile of dietary and plasma magnesium. In conclusion, higher plasma concentrations and dietary magnesium intakes were associated with lower risks of SCD in women. If the observed association is causal, interventions directed at increasing dietary or plasma magnesium might lower the risk of SCD.
This adds more evidence to the even stronger October study in American Heart Journal
