Background. The high prevalence, poor prog-nosis of patients with coronary heart disease with chronic heart failure determine the relevance of the study pathophysiological and molecular mechanisms of this pathology. Researches of the trace element metabolism in the myocardium are scarce. With this in mind, an attempt was made to analyze the relationship of macro and trace elements metabolism with the functional state of the myocardium in coronary heart disease patients against the background of chronic heart failure progression. Methods and Results. To study the content of the chemical elements (S, K, Ca, Cr, Fe, Ni, Cu, Zn, Se, Rb, Sr) in the myocardium of 43 patients with coronary heart disease, use was made of X-ray fluorescence with synchrotron radiation. While doing autopsy, 43 samples of left ventricle myocardium were taken off the cardiac callosity. Myocardium samples were subjected to histological examination. Dynamics of macro and trace elements content in the myocardium reflects the development of energy deficiency and disorders of myocardial microcirculation with a decrease of systolic myocardial function. Structural/functional disorders in the myocardium of the left ventricle of patients with coronary heart disease that accompany the progression of chronic heart failure are associated with profound changes of metabolic processes in heart muscle. Conclusions. The structural/ functional changes accompanying chronic heart failure progression are associated with wide variations of metabolic processes in the myocardium, which could be evaluated by the content of chemical elements in tissue.
