Hypomagnesemia Inhibits Nitric Oxide Release From Coronary Endothelium: Protective Role of Magnesium Infusion After Cardiac Operationshttp://ats.ctsnetjournals.org/cgi/conte ... t/65/4/967
Background. Postoperative hypomagnesemia is common in patients who have undergone cardiac operations and is associated with clinically significant morbidity resulting from atrial and ventricular dysrhythmias. Magnesium supplementation may increase the cardiac index in the early postoperative period.
...The removal of magnesium from the organ chamber solution impaired vasodilation in response to acetylcholine and adenosine diphosphate. However, normal endothelium-dependent vasodilation could be restored by return of magnesium to the bathing solution. ... Conclusions. Hypomagnesemia selectively impaired the release of nitric oxide from the coronary endothelium. Because nitric oxide is a potent endogenous nitrovasodilator and inhibitor of platelet aggregation and adhesion, hypomagnesemia could promote vasoconstriction and coronary thrombosis in the early postoperative period.
ms patients are known to have lower average magnesium status - optimizing prior to any procedure looks like it would be wise.
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
