Screening of Cardiovascular Disease in Kazakhstan

Abstract

Background: Mass screening is an effective way to detect the risk of cardiological diseases early. Still, the main problems during mass screening are the availability of screening methods and the efficiency of disease intelligence with a minimum expenditure of time. Method of dispersive ECG charting proves to be the most effective from the point of sensitivity to metabolic changes in the Myocardium of any origin (it provides a 95 % probability of detection of heart disease at an early stage) among non-invasive, easy-to-use methods of control accessible for broad clinical practice. This method also provides unique information unobtainable by other methods in real-time regarding transient functional disorders that are precursors of pathology. Objective: The purpose of the study was to examine the dispersive ECG charting indexes related to various factors of risk of cardiovascular disorders among the rural population of the southern region of Kazakhstan. Method: We screened 500 rural residents of the Zhambyl Region of Kazakhstan to assess the state of the cardiovascular system. 12 standard derivations and the dispersive ECG data were recorded using the Heart Screening System “CardioVisor 12C”. The “Statistika 7” program processed statistical data. Results: We observed the depreciation of the Myocardium’s compensatory mechanisms, violations of the Myocardium’s electrophysiological properties, and autonomic dysfunction in heart rate with age. Conclusion: The study revealed the highest percentage of changes in the cardiovascular system in virtually healthy people aged 40-49, which might indicate the need for a dynamic monitoring of health and timely preventive measures.
