CARE-2 (Calcium Acetate [PhosLo®]/Sevelamer[Renagel®] Evaluation Study 2) for Heart Calcification in Dialysis Patients

Summary

The purpose of the study is to evaluate the effects of two phosphate binders, PhosLo and sevelamer, on heart calcification in dialysis patients. The study will use a non-invasive technique, electron beam computed tomography (CT) scanning, to measure calcium in the coronary arteries, the aortic valve, and the mitral valve.
