Aim: To perform calcium scoring (CAS) in a group of patients with chronic renal failure treated by hemodialysis. CAS is playing an important role in screening for coronary artery calcification. The result of CAS is Agatston score, an independent factor for increased cardiovascular mortality rate.

Method: Our study was performed in a group of 72 hemodialysis patients. All patients underwent computed tomography examination of the bone mineral density and calcium scoring. Detected values of Z-score and CAS were correlated with levels of intact parathormone (iPTH), calcium (Ca), phosphorus (P), calciumphosphorus product (CaxP), duration of hemodialysis, vitamin D treatment and history of diabetes mellitus. The tests were repeated after one year and the results were compared.

Results: Correlation between increased CAS (very high risk of cardiovascular mortality) and increased levels of phosphorus (p = 0.01) and increased calciumphosphorus product (p = 0.004) was statistically significant. There was a significant increase of CAS within one year (p = 0.0001).

Conclusion: Patients with chronic renal failure and disorders of calcium-phosphate metabolism are threatened by ectopic calcification deposits. Calcium scoring is an independent factor for assessment of increased cardiovascular mortality rate.
