Low blood levels of magnesium increase the risk for death from cardiovascular disease, according to a study from the University Medical Center Rotterdam, The Netherlands. Blood levels of magnesium and risk for heart disease were monitored for 8.7 years in a group of 9,820 men and women with an average age of 65.1 years-old. Blood magnesium levels were divided into four categories from low to high. Results showed low blood levels of magnesium (< 0.80 mmol/L) were associated with a 36% increased risk for cardiovascular death. Low magnesium also was associated with subclinical atherosclerosis and altered heart rate.
In Perspective: Several studies show an inverse correlation between magnesium and cardiovascular risk. High magnesium intake also might lower the risk for stroke and high blood pressure, while low magnesium intake appears to increase a person’s risk for arrhythmias and heart attack. Finally, a few studies show that magnesium combined with aspirin therapy might provide an additional benefit in preventing blood clots.
