Abstract:
OBJECTIVE:To evaluate several potential clinical indicators of magnesium status (diet, blood, urine, 24-hour load retention) in patients with congestive heart failure before, during, and after oral magnesium supplementation. METHODS:Twelve patients with New York Heart Association class II-III heart failure and 12 age and sex matched healthy control subjects were supplemented with 10.4 mmol oral magnesium lactate for 3 months. For the determination of magnesium status, samples of whole blood, serum, plasma, red blood cells, and urine (24-hour) were collected. Four-day dietary intake records were reviewed. A 4-hour IV magnesium load retention study was performed before and 3 months after magnesium supplementation. A non-supplemented control group was similarly studied. RESULTS:At baseline, magnesium intakes for all groups were below the RDA. No significant differences were seen in serum, plasma, ultrafiltrates of serum or plasma or red cell magnesium concentrations among groups over time. At baseline 5/27 subjects (19%) compared to 11/27 subjects (41%) after supplementation demonstrated normal magnesium retentions (< 25%). Magnesium excretions among groups were significantly different during supplementation. Percent magnesium retentions among groups were not different. CONCLUSIONS:Supplementation with 10.4 mmol oral magnesium daily for 3 months did not significantly alter blood levels or magnesium retention; however, patients demonstrated lower retention of magnesium after supplementation. Differences in magnesium retention was not related to basal magnesium intake, blood levels or excretion. Unfortunately, even an intensive effort at characterizing magnesium status did not identify a clinical indicator of utility for differentiating patients with congestive heart failure before, during, and after 3 months of magnesium supplementation.
