OBJECTIVE: To determine the relationships between inflammatory mediators, mitral annular calcification (MAC), and osteocalcin in patients with chronic kidney disease (CKD).
MATERIALS AND METHODS: Echocardiographic data for 60 patients diagnosed as CKD were retrospectively evaluated. The patients were divided into 2 groups; patients with MAC (MAC+ group) and patients without MAC (MAC- group). The relationships between biochemical markers-including osteocalcin-and MAC were evaluated.
RESULTS: The study included 19 female and 41 male patients. In all, 29 patients were MAC+ and 31 were MAC-. High-sensitive C-reactive protein (hsCRP) and osteocalcin levels were significantly higher in the MAC+ group (p < 0.05). The eGFR was lower, serum calcitonin (we could not obtain calcitonin data for 15 patients), Ca, PO4, CaxPO4, the erythrocyte sedimentation rate, red cell distribution width, the neutrophil/Lymphocyte rate, and PTH were higher in the MAC+ group; however, the differences between the groups were not significant (p > 0.05). The mitral E/A ratio, mitral peak Ea velocity, tricuspid E/A ratio, hsCRP, and the osteocalcin level were strongly correlated with MAC. Multivariate logistic regression analysis showed that only the osteocalcin level and mitral E/A ratio were independent variables, each with an independent effect on MAC.
CONCLUSION: CKD patients in the MAC+ group had higher osteocalcin levels than those in the MAC- group, and left ventricular diastolic dysfunction was more common in the MAC+ group.
