Abstract
BACKGROUND
Magnesium depletion and hypomagnesemia are common among furosemide-treated patients with chronic congestive heart failure.
HYPOTHESIS
This investigation evaluated clinical and metabolic effects of oral magnesium supplementation.
METHODS
Ten patients with severe congestive heart failure maintained on high dose furosemide (> or = 80 mg/day) received a supplement of oral magnesium citrate 300 mg/daily for 30 days. Clinical parameters were followed, and peripheral blood mononuclear cell magnesium and zinc content, serum and urine magnesium, potassium, zinc, calcium, phosphorus, and creatinine were assessed.
RESULTS
Peripheral blood mononuclear cell magnesium content and serum potassium rose significantly at the end of the study (2.09 +/- 1.89 to 3.99 +/- 2.26 micrograms/mg cell protein, p < 0.05, and 4.17 +/- 0.38 to 4.39 +/- 0.27 mEq/l, p < 0.05, respectively), while the other parameters remained unchanged.
CONCLUSION
In some of these patients, oral magnesium supplementation is effective in achieving substantial increments in intracellular magnesium and serum potassium which, in turn, may have cardioprotective effects.
