An attempt is made, herein, to reconcile, and integrate, various phenomena associated with magnesium deficiency (MgD) in cardiovascular health, disease, and aging as well as reasons for the high incidence of sudden cardiac death in infants and young adults. With new experiments, we demonstrate, for the first time, that very low concentrations of platelet-activating factor (PAF), when added to primary cultured cerebral, neonatal coronary, and aortic vascular smooth muscle (VSM) cells (from three different mammals) promote rapid rises in free intracellular Ca2+ ions and a significant, concomitant reduction in free intracellular Mg2+ ions; these actions of PAF being curtailed with …

Epidemiologic studies in North America and Europe have shown that people consuming Western-type diets are low in magnesium (Mg) content (i.e., < 30 - 65% of the RDA for Mg); most such diets in the USA show that 60 - 80% of Americans are consuming only 185 - 235 mg/day of Mg. Low Mg content in areas of soft-water, and Mg-poor soil, is associated with high incidences of ischemic heart disease (IHD), coronary artery disease, hypertension, and sudden cardiac death (SCD). It is clear that the leading underlying cause of death worldwide is atherosclerosis. Importantly, both animal and human studies have shown an inverse relationship between dietary intake of Mg and atherosclerosis. The myocardial level of Mg has consistently been observed to be lower in subjects dying from IHD and SCD in soft-water areas than those in hard-water areas. Over the past 20 years, our laboratories, using several types of primary cultured vascular smooth muscle (VSM) cells, and myocardial cells, demonstrated that declining levels of extracellular Mg ([Mg2+]0) activated several enzymatic pathways to produce increases in cellular sphingolipids, particularly ceramides which are known to exert numerous types of cardiovascular manifestations including inflammatory effects; the latter play important roles in atherogenesis and cardiovascular diseases. Approximately 20 years ago, we reported that low [Mg2+]0 caused formation of platelet-activating factor (PAF) as well as other types of PAF-like molecules and suggested that these molecules might be causative agents in low Mg2+- induced IHD and SCD. Herein, we review results and data from our labs which strongly support roles for ceramides, PAF and PAF-like lipids in low [Mg2+]0-induced IHD and SCD.

The authors present evidence for a novel, new hypothesis whereby magnesium deficiency (MgD) acts as a genotoxic agent which probably causes numerous, hertofore, unrecognized consequences, even over a short-term, on the physiological, molecular and biochemical machinery of cardiovascular tissues and cells. The end result of these genotoxic effects of MgD probably plays important roles in the etiology and generation of diverse cardiovascular diseases, atherosclerosis, inflammation, and strokes via alterations in the epigenome of cardiovascular tissues and cells. The importance of adequate water-borne and dietary levels of Mg is emphasized.

Magnesium (Mg) is a co-factor for more than 500 enzymes, and is the second most abundant intracellular cation after potassium. It is vital in numerous physiological, cellular and biochemical functions and systems necessary for life. Approximately 35 years ago, our laboratory suggested that a progressive, dietary deficiency and/or metabolic induced loss of Mg from the body, beginning early in life, particularly during development of the coronary arteries, could lead to coronary arterial vasospasm, ischemic heart disease, and sudden-cardiac death (SCD). Herein, we review evidence for a brand-new, novel hypothesis which combines knowledge suggesting a combined role for hypomagnesemia and platelet-activating …
