Our aims were to determine the prevalence of VC in our maintenance haemodialysis (HD) population and to examine some possible aetiologic factors for its occurrence.<\/jats:p><jats:p><jats:bold>Methods:\u2003<\/jats:bold> We studied 90 patients (47 women) on maintenance HD for more than 12\u2003months. An M\u2010mode two\u2010dimensional echocardiogram was carried out to evaluate mitral, aortic VC and ventricular geometry. We calculated mean daily calcium intake for the phosphate intestinal chelaing in the previous year to echocardiogram date and also mean values from previous year of Ca, PO4, Ca\u2003\u00d7\u2003PO4, parathyroid hormone, lipide profile, nutritional and inflammatory marquers. Finally consumption of calcium and alfacalcidol was also noted.<\/jats:p><jats:p><jats:bold>Results:\u2003<\/jats:bold> Thirty\u2010six patients (40%) presented with VC.
