OBJECTIVES: This study sought to clarify the differences of intracellular and extracellular magnesium levels in patients with cardiac syndrome X.
METHODS: We evaluated the intracellular and extracellular magnesium status of 22 patients with cardiac syndrome X (group A) and 22 age--and gender--matched disorder-free control subjects (group B). Levels of magnesium were determined in serum, urine, erythrocytes, and the 24-h magnesium retention rate was calculated by a magnesium loading test.
RESULTS: Group A showed a higher 24-h magnesium retention rate (49.8 +/- 1.3% vs. 32.6 +/- 7.5%, p < 0.05) and a lower intracellular concentration of magnesium in erythrocytes than group B (3.7 +/- 1.4 vs. 5.6 +/- 1.3 fg/cell, p < 0.05), demonstrating the presence of magnesium deficiency in group A. There were no significant differences in the serum concentration of magnesium between groups A and B (0.87 +/- 0.23 vs. 0.83 +/- 0.15 mmol/l).
CONCLUSIONS: This study demonstrated that the intracellular magnesium level decreased in patients with cardiac syndrome X.
