Russian Academician Vasily V. Parin was one of the leading world scientists in the field of physiology of blood circulation. In this article his role in the development of the space cardiology, an important area of space medicine, is considered.
In order to evaluate the vegetative regulation of blood circulation and assess individual health risks under conditions of the 520 day isolation, used was an analysis of the heart rate variability (HRV). The most significant changes in the HRV values against the background data were reported in the second half of the said experiment.
The article presents the results of space experiment “Pneumocard”. The investigation involved all 25 Russian members of the ISS crew. The total of 226 sessions were made including 130 aboard the ISS, 50 prior to launch and 46 on return from mission.
Research methodology and methods used in experiment Mars-500 held at the Institute of Biomedical Problems of the Russian Academy of Sciences in 2009-2011 are considered. 6 volunteers were isolated during 520 days in a sealed ground-based facility simulating space ship.
The paper presents the results of the long-term medical & ecological investigations conducted during the experiment Mars-500. Methodology of conducting the long-term medical & ecological investigations and the applied methods are considered.
The article presents the main provisions of the methodology for the analysis of heart rate variability (HRV), which is now actively and widely implemented in many fields of medicine and applied physiology.
The Sonocard experiment purpose was a noninvasive physiological signal recording from sleeping humans. In 2007-2012 the experiment was made by 22 Russian members of 17 missions to the International space station. Of the overall 302 experimental sessions 47 were performed pre, 215 in and 40 after flight.
Experience of cosmonauts’ health monitoring shows that in the study of healthy subjects clinical approach to the evaluation of various medical and physiological data is almost less effective than the evaluation of organism adaptive abilities. The idea of prenosological diagnosis and the concept of adaptive risks develop in space medicine last years. These new space technologies are being actively tested in terrestrial studies in systems as "home medicine".
Monitoring the health of astronauts based on the assessment of the functional state of the body within the realms of norm and pathology. The area of functional states qualifies as the yellow score of health on a notional scale "traffic light of health": Modern medicine is particularly interested in studying the health of the yellow score, because of the preventative measures that could still be taken before making contact with the healthcare system.
The paper is devoted to research and development of a new, based on Multiscale Correlation Analysis method of PVC (premature ventricular complexes) extra beats and SPB (supraventricular premature beats) online detection.
The detected phenomena of shunting of blood from large arterial trunks into large venous vessels is considered herein. The Cardiocode device is capable of detailed visual interpreting of a change or a significant reduction of a rheographic wave of the ascending aorta.
Consideration is being given herein to some mechanisms of high heart rate variability (high HRV), which cannot be attributed to sports exercise loading. The mechanism responsible for high HRV is explained as that resulted from the continuous performance (opening and closure) of arteriovenous anastomoses in different organs and systems in a human organism.
The paper presents issues on actions and effects made by the discovered phenomena of shunting in the blood flow, when blood is directed from large artery vessels into large-sized venous vessels, on the hemodynamics profile of the proper heart.
The article presents experimental evidence of the validity of the hypothesis that theoretical construct “ego state”, in addition to the psychological content, actually reflects the physiological mobilization of a human individual to provide a certain type of response. It is shown that the mobilization is manifested in a certain specific pattern inherent to the cardiovascular system performance.
Cardio-oсulometric indicators to grade psychophysiological readiness of students to examinations are described herein. Given is an experimental evidence that transitions from a low level of psychophysiological readiness of students to examinations to a high level of such readiness thereto is really accompanied by significant changes in the organism performance, first of all, in that of the heart. It is shown that a reliable marker of such changes is the heart rate variability assessment using the Baevsky stress index (SI), as well as the oculometric peculiarities of response to the visual stimuli, which students associate with their upcoming examinations.
The paper presents our experimental evidence of validity of our hypothesis that definite, substantively different, psychophysiological states of a human individual can be really fixed with the use of metaphoric associative cards, and that transitions from one psychophysiological state to another are accompanied by significant changes in the performance of the human organism, and, first of all, in the performance of the heart.
We have performed the study of the effects made by the automated plasmapheresis application on ischemic heart disease clinical manifestations, echocardiographic indices and heart rate variability in patients with exertional angina III-IV functional class. It has been found that the applied plasmapheresis method is capable to reduce the severity of the disease clinical manifestations and improve the echocardiographic characteristics of the heart, in particular, reduce the level of end-diastolic volume, and increase ejection fraction.
