[Significance of serum calcium and phosphorus control for the cardiac function in patients with long term hemodialysis].

We evaluated how serum calcium and phosphorus will effect a cardiomegaly of hemodialysis patients. The cardiac valve of hemodialysis patients have a high incidence of calcification. Forty four percent of mitral valve and seventy five percent of aortic valve occurred the calcification, and the progress of calcification involve with increasing LVMI. The consequence of this results was that we consider prevent calcification is important to inhibiting factor of cardiomegaly, but serum calcium and phosphorus wasn't effect a cardiomegaly. On the other hand, we detected a significant negative correlation between serum calcium and LVMI (P = 0.0008) and a significant positive correlation between serum phosphorus and LVMI (P = 0.0105) . Consequently we thought that to control the serum phosphorus is important factor to inhibit the cardiomegaly.
