Coronary heart disease (CHD) is a leading cause of death and disability worldwide, affecting millions of people annually. While it is traditionally considered to be more common in older adults, an alarming increase in the incidence among younger patients has been observed in recent decades. In young adults, CHD can present atypically, complicating timely diagnosis and treatment [1]. This circumstance highlights the need for a more in-depth study of CHD diagnostic methods in young patients. The sympathetic-adrenal system mediates its adaptive effects through specific chemical messengers, catecholamines, the ratio and level of which in the myocardium is an important physiological constant and is of wide scientific interest.
