Relationship between serum magnesium level with coronary artery calcification and mineral metabolism in patients receiving peritoneal dialysis

Objective To explore the relationship between serum magnesium level with coronary artery calcification(CAC) and mineral metabolism in continuous ambulatory peritoneal dialysis (CAPD) patients. Methods 72 patients receiving CAPD in the Peritoneal Dialysis Center were enrolled prospectively. The CAC was detected by multi-slice spiral computed tomography, and the CAC score(CACs)was calculated. According to the CACs the patients were divided into group A(CACs ≤ 100) and group B(100Results The serum magnesium levels in group A were significantly increased as compared with those in group B and group C (P<0.05). There was negatively correlation between serum magnesium and iPTH (r=-0.311,P<0.05),serum phosphorus (r=-0.306,P<0.05) and CACs (r=-0.47, P<0.01). There was no significant correlation between serum magnesium and serum calcium. Conclusions CAC and mineral metabolism disorder are the frequent complications in CAPD patients.The serum levels of serum magnesium may be correlated with the CAC, iPTH and serum phosphorus.
