Abstract

BACKGROUND: Extra-skeletal calcification and disordered phosphate metabolism are hallmarks of chronic kidney disease-mineral bone disorder (CKD-MBD). Osteoprotegerin (OPG) and fibroblast growth factor 23 (FGF-23) are increased in chronic kidney disease (CKD) and have been associated with arterial and cardiac dysfunction and reduced survival. Troponin T (cTnT) is released from cardiac myocytes under conditions of stress and is predictive of mortality across a range of renal functions. However, the utility of this biomarker was formerly limited by the lower limit of assay detection. The introduction of a high-sensitivity assay has enabled more detailed study of myocyte stress below the previou..
