When conducting an echocardiographic examination of children with chronic kidney disease, it was found that in children with cardiovascular disorders against the background of chronic kidney disease, characteristic changes in echocardiographic indicators are noted: an increase in the mass of the left ventricular myocardium, the volume of its cavity, and a change in the size of its walls. In all children with cardiovascular changes, signs of myocardial remodeling were found, concentric hypertrophy was noted in 48.4% of observations, the presence of concentric remodeling in 27.9% of cases, and eccentric hypertrophy in 23.8% of cases.
