Vascular and valvular calcifications in chronic hemodialysis patients

Abstract

Introduction: Vascular and valvular calcifications are a frequent complication in dialyzed patients and are connected to an increased morbi-mortality. Many radiological methods (TAC multiple slices and with electrons emission) have been used to investigate the presence of vascular calcifications in this population, but only few works have been focused on simple radiology. Objectives: The objectives of this work are to evaluate vascular calcifications by means of Kauppila index in hemodialysis prevalent patients, identify linked risk factors and determine their association with heart valves calcification. Methods: 95 stable patients under hemodialysis were surveyed during a period of 6 months longer. Abdominal Rx simple profile were performed on all patients to evaluate calcification of abdominal aorta by Kauppila index and twodimensional echocardiogram to detect valvular calcifications. Data were collected about sex, age, diabetes, Hypertension, tabaquism, dislipemia and bone-mineral metabolism. Results: 64.5% of the patients showed vascular calcifications. Average Kauppila index was 6.25. Age and time on dialysis correlated with vascular calcifications. In 31.6 % of individuals valvular calcifications were found, which presented significant association with diabetes and Kauppila Index. Conclusions: Vascular and valvular calcifications were frequent in the surveyed population. Kauppila index correlated with age, time on dialysis and valvular calcifications. Heart valves calcification was associated with diabetes.
