Abstract: The use of a systematic approach to the study of the etiology of a certain pathology makes it possible to improve the understanding of its pathogenesis, as well as to develop more effective diagnostic and therapeutic approaches, including improving the prediction of its risk. Within this review, we will consider such an area of interdisciplinary research as neurocardiology, which studies the brain-heart axis. Examples of cardiovascular diseases associated with organic and functional disorders of this axis will… Show more

Aim. Interoception reflects the perception, integration and modulation of visceral signals. Currently, there is no established universal approach to cardiac interoception assessment allowing its inclusion in the diagnostic protocol for various diseases. The aim was to compare three tests of interoception self-assessment based on heart palpitations within one day in healthy subjects.Material and methods. Eighty healthy volunteers took part in the study. To assess cardiac interoception, a test with button pushes at the moment of palpitations, a feedback test in the form of synchronous and asynchronous sound signals, a heartbeat counting task at specified time intervals were conducted with simultaneous electrocardiographic recording. The obtained data were compared with each other (Wilcoxon test). Its pairwise dependence (Spearman coefficient) and dependence on body parameters (sex, age, body mass index, fat mass, anxiety) were assessed (univariate linear regression).Results. The accuracy of the heartbeat counting task turned out to be significantly higher than in the button- pressing test (p=0,005). However, both estimates correlate with each other (r=0,66, p=0,003). A positive dependence of test accuracy on sex was found for the heartbeat counting task (p=0,021) and a negative dependence on fat mass for button- pressing task (p=0,032).Conclusion. The study found that volunteers' estimates of heartbeat accuracy varied across tests and were also associated with sex and body composition. The heart rate counting task and the button- pressing task are the most suitable for interoception assessment.

The work is aimed at identifying the features of the mechanisms of regulation of cardiac rhythm, which determine adaptive behavior in situations of health disorders. Materials from two empirical studies conducted on a sample of 1st to 4th year students at Yelets University are presented. The study 1 (N=160) involved respondents aged 17 to 23 years of both sexes, of whom 37.5% had various health problems. In study 2 (N=60), students (average age 21±2.3 years), of which 50% belong to the category of chronically ill, 50% had periodic health problems. Study 2 included five stages, in which four levels of the internal picture of the disease (IPD) were diagnosed and cardiac rhythm measurements were performed at rest and against the background of existing disease memories. The following methods were used: SF-36 Health Status Survey, Health, Activity, and Mood questionnaire, SCL-90-R, “Coping behavior in stressful situations”, “Level of subjective control”, TATD method. The fixation of the heart rate variability was carried out using the hardware and software complex OMEGA-M. The results obtained allow us to say that there is a correlation between the individual components of IPD and the parameters of regulation of heart rate variability. The optimal state of the body's homeostatic systems, which ensure successful adaptation, is characterized by the activity of the parasympathetic department of autonomic nervous system in the process of cardioregulation.
