Abstract
In the past ten years, Moldova has seen a rise in chronic pathologies. Among these diseases, thyroid gland pathology has stood out, influenced by the ecological state, as a consequence of environmental pollution with chemical
waste and iodine deficiency.
The concentration level of sodium and potassium ions in the blood is minimally altered in the early stages of
diffuse thyrotoxicosis. However, in patients with diffuse thyrotoxicosis associated with fibrillatory arrhythmias,
these changes are more noticeable. In all stages of thyrotoxicosis, an increased level of thyroid hormones has been
observed. The evolution of diffuse thyrotoxicosis shows changes in cardiac activity, which involve the increased
tension of the regulatory mechanisms and the reduction of the functional reserves of the body. A reduced functional reserve coefficient indicates a decrease in the body’s adaptive capacity and its ,,physiological output”.
Keywords: thyrotoxicosis, cardiovascular system, epidemiology, thyroid gland diseases, iodine, physical exertion.
