• Coronary artery calcium score (CACS)

Renal diseases pose a growing epidemiological and health problem worldwide. Cardiovascular diseases are the leading cause of deaths among patients with chronic kidney disease. Increased risk of atherosclerosis in these patients results from the occurrence of traditional and non-traditional risk factors. The aim of this study was to assess the relationship between selected risk factors for cardiovascular diseases (age, sex, dyslipidemia, hypertension, etc.), intima-media thickness and coronary artery calcium score in patients with chronic kidney disease stages 2, 3 and 4. This study included 60 patients with chronic kidney disease divided into 3 groups on the basis of disease stage and control group consisting of 20 individuals without diagnosed chronic kidney disease and cardiovascular diseases. Blood analysis and blood pressure measurements were taken. All patients underwent carotid artery ultrasound with the assessment of the intima-media thickness, and heart CT scan in order to assess the index of coronary artery calcification. Logistic regression analysis revealed statistically significant correlation between blood vessels calcification and age-the increase in age by 1 year was associated with the increase in the risk of coronary artery calcification by 6.7 %. The increase in IMT by about 0.1 mm raises the risk of calcification by about 2 %. Second logistic regression model revealed that one-year increase in age was associated with an increase in the risk of intima-media thickening by 6.5 %. Occurrence of hypertension was associated with a ninefold increase in intima-media thickening risk in comparison with patients with normal blood pressure. To sum up, age and hypertension were associated with the growth of IMT in CKD patients, while age and exposure to tobacco smoke were associated with the increase in coronary artery calcium score. The relationship between thickening of IMT and the increase in calcification index in patients was also observed in study group.
