Abstract (original English)

Background Autonomic innervation of the heart plays a pivotal role not only in regulating the heart rate but also in modulating the cardiac cell microenvironment via cell-cell interactions and influencing the heart's repair capabilities. Currently, the primary clinical approach for treating myocardial infarction (MI) is percutaneous coronary intervention. However, the myocardial salvage rate remains low for patients with advanced disease. MI is recognized as an autonomic nervous system disorder, marked by sympathetic hyperactivity and the loss of parasympathetic nerves. Following MI, ventricular sympathetic nerve sprouting occurs, leading to an increase in ventricular sympathetic innervation and, consequently, an increased risk of ventricular arrhythmia, which is the primary cause of sudden cardiac death in patients with a history of MI. The vagus nerve positively regulates cardiomyocyte proliferation and regeneration, enhancing ventricular remodeling and cardiac function post-MI. This process is highly significant in the treatment and rehabilitation of MI. Cardiac autonomic nerves are influenced by factors such as inflammation, immunity, intercellular communication, metabolism, genetics, epigenetics, and cytokine secretion related to cardiac mesenchymal nerves. In recent years, significant advancements have been made regarding treatment for MI, specifically in the fields of au
