[Features of the intestinal microbiota in the elderly in the development of coronary heart disease.].

The review is devoted to the influence of the microbiota on the development of such an age-dependent disease as coronary heart disease, the formation of which depends on atherogenesis in particular. According to the World Health Organization, cardiovascular disease is the leading cause of death worldwide. Statistical data from the Federal State Statistics Service also confirm that coronary heart disease is the leading cause of death in the Russian Federation today. It is known that the vast majority of cardiovascular diseases are atherosclerosis-associated pathologies. Atherogenesis and the state of the human gut microbiome are dynamically interrelated. The gut microbiota, which consists predominantly of bacteria, plays an important role in maintaining homeostasis. The pathogenesis of atherosclerosis is based on systemic inflammation. Aging is accompanied by a wide variety of clinical manifestations, including a basic pro-inflammatory state (i.e., «inflammation-aging»), the activity of which is maintained by the microbiota in older individuals and increases their susceptibility to diseases. Intestinal microbiocenosis in elderly and senile people differs from those of young people. In persons of older age groups, there is an increase in microorganisms secreting endotoxins lipopolysaccharide and trimethylamine-n-oxide, initiating and maintaining chronic inflammation. More research is needed to study the mechanisms of action of microbial metabolites and their clinical application in various therapeutic interventions.
