INFORMATIONAL VALUE OF VISUAL ANALYSIS OF ARTERIAL OSCILLOGRAPHY, DETERMINED AT THE TIME OF GROWTH OF FOOT COMPRESSION AFTER MEASUREMENT OF ARTERIAL PRESSURE
Background. The implementation of modern ICT in health care practice makes it possible to improve prevention, diagnosis, early rehabilitation and treatment of cardiovascular system (CVS). According to the World Health Organization each year cardiovascular diseases (CVD) cause the death of 17.5 million persons; it is 31% of all deaths worldwide). High blood pressure is a major risk factor for heart attacks. The current instrumental diagnostics of CVS disorders by ultrasonic Doppler examination, ultrasound scanning and digital optical capillaroscopy, MR angiography, mathematical analysis of cardiac rhythm, Holter monitoring (and other methods) contribute to improving the diagnosis and treatment of CVS diseases. However, «rejuvenating» of vascular disorders that lead to profound disability, indicates that today there is an urgent need in fundamental studies on cardiovascular system, changes in cases of pathological conditions, effective technologies for early detection and treatment of vascular pathology.
Materials and methods. Arterial oscillogram obtained using monitor of blood pressure and heart rate, which records the value of pressure pulse changes in cuff when measuring blood pressure and export information through an external
interface of data exchange to personal computer. Further analysis of the obtained data and creating of arterial oscillogram was conducted by computer programs developed by the authors.
The results of our research are based on assessment during 2012-2017. 626 people - volunteers were divided into 2 groups. The first group consisted of 480 healthy males (27 %) and females (73 %), aged 18 - 22 years, who study in the medical and pedagogical universities of Ternopil, Ukraine.
Results. The authors suggested morphological criteria of oscillograms evaluation, defined standards of normal findings; developed the ICT methods of value oscillogram evaluation, differentiated 5 levels of deviations from the norm, which are compared with 5 types of health level gradation established in electrocardiography.
Morphological oscillogram analysis enables visual evaluation of vessels condition before compression and their oscillatory ability to counteract compression increase by the cuff when measuring blood pressure. The nature of pulsation will help the doctor to examine pulsation rhythm, cardiac function, and condition of the autonomic nervous system, blood pressure and neuro-reflex effects on the blood vessels state, differentiate functional and organic causes of changes in them. The use of the suggested morphological criteria of value oscillogram evaluation to estimate health condition will help the doctor to take appropriate decisions both during primary examination, and for monitoring the effectiveness of treatment.
Conclusions. So, the suggested information technology enables medical professionals to expand information on cardiovascular system of patients, promote early revealing of premorbid and donozological state and help to plan diagnostics and therapy. They will be useful for general physicians, paediatricians, cardiologists, neurologists, researchers, in sports medicine. General physicians (or other users) in the presence of electronic sphygmomanometer and the software will be able to monitor CVS state and peripheral vessels according to the suggested criteria.
