Uncovered mechanisms of cardioprotection in thyroid dysfunction | Ukrainian Medical Journal

Today, thyroid pathology affects more than 10% of the world’s adult population. In most patients with thyroid disease, there is a change in the concentration of thyroid hormones, which are involved in the regulation of the metabolism of almost all organs and systems. The cardiovascular system is very sensitive to fluctuations in the concentration of thyroid hormones, as evidenced by the increased prevalence of cardiac pathology and mortality in patients with thyroid dysfunction. The article presents various mechanisms by which thyroid hormones affect the cardiovascular system, describes the hemodynamic disturbances observed in hypo- and hyperthyroidism. It has been shown that timely treatment of even subclinical thyroid pathology and normalization of thyroid hormone levels has a potential benefit in preventing cardiovascular complications. The use of a combination of two biologically active substances — L-carnitine and L-arginine as an additional means of pathogenetic therapy of metabolic disorders associated with thyroid gland dysfunction is pathophysiologically justified.
