Abstrakt		Vascular calcification is a frequent complication of chronic kidney disease and end stage renal disease. In both the general population and patients with end stage renal disease, vascular calcification is related to arterial stiffness and is a predictor of cardiovascular morbidity and mortality. Various diagnostic methods are currently used to assess vascular calcification. There is a preference for simple, reliable methods that can be used in daily practice. Therefore, several imaging and laboratory methods are investigated. Twenty-eight patients with mean age of 62 years on chronic hemodialysis were enrolled in the study. The mean duration of hemodialysis treatment was 70 months (range 3 to 350 months). Vascular calcification was assessed with coronary computed tomography and lateral lumbar, pelvic and hand radiographs. Vascular stiffness was evaluated using aortic pulse wave velocity and ankle-brachial index measurements, and finally serum levels of fibroblast growth factor-23 were followed. A statistically significant correlation was demonstrated between all the following parameters: coronary artery calcification score, aortic pulse wave velocity, abdominal aortic calcification score, simple vascular calcification scores in pelvis and hand. A statistically significant correlation of ankle-brachial index >1.3 to coronary artery calcification score was found. There was no correlation between the previous parameters and fibroblast growth factor-23. The results of our study indicate that simple imaging methods could provide confident vascular damage assessment and therefore potentially guide therapy adjustments. An association between fibroblast growth factor-23 and the other diagnostic modalities in our study was not found.
