Cardiac valve calcification is associated with presence and severity of coronary artery disease in patients with pre-dialysis chronic kidney disease

Background Cardiac valve calcification is common in chronic kidney disease (CKD) patients. Coronary artery disease (CAD) is the one of major causes for increased cardiovascular mortality in CKD patients. We hypothesized that cardiac valve calcification is associated with the presence and the severity of CAD in pre-dialysis CKD patients.
