Role of sevelamer hydrochloride in the coronary artery calcification score.

The coronary artery calcification score (CACS) is higher in hemodialysis (HD) patients than in non-HD patients for each age group from the fifth to the eighth decade of life. In order to clarify the relationship between the rate of change in the CACS and several factors related to calcium (Ca) and phosphate (P) metabolism in HD patients, we determined the CACS twice in 144 HD outpatients at an interval of approximately 12 months (2003 and 2004). The dosage of vitamin D formulations (alfacalcidol or maxacalcitol) was reduced or ceased if the serum Ca concentration exceeded 5.
