The urgency of the problem under study is determined by the high prevalence of arterial hypertension among the indigenous minorities of the North in modern socio-economic conditions. The following article is aimed to evaluate the prevalence of behavioural arterial hypertension risk factors according to the results of single-step epidemiological research of Evenk people in the Republic of Sakha (Yakutia), Russian Federation. The leading approach to the study of this problem was the questioning of the population using the international questionnaire for behavioural risk factors (CYNDI). As a result of research, widespread smoking was found among native population (52.0% of men and 23.7% of women). The frequency of alcohol consumption among the male Evenki is comparable to that in the Yakut population, and among the female, the number is much lower. Evenks including young men belong to the physically inactive population. The frequency of arterial hypertension (AH) cases along with the factors listed above are significantly influenced by: marital status, employment, education, and housing conditions. Article materials may be useful for a differentiated approach in the development of prevention and rehabilitation programs for the indigenous peoples of the North.

The paper describes echocardiographic values of systolic and diastolic dysfunction the right heart ventricle in 229 patients with chronic obstructive pulmonary disease. In our patients the values AvPAP (≥25 mmHg while resting), FDDrv and FSDrv (>26 and 20 mm respectively), the thickness of front wall the RV (>5 mm), the dimension of AD (>35 mm), as well as the reduction the vestibular-distal shortening of RV (<23%), maximum blood velocity and the blood evacuation time from reflect indirectly the progressive reduction the contractive capacity RV myocardium and the occurrence of systolic dysfunction. In patients with severe de-compensation a restrictive type diastolic function is more characteristic – acceleration of early diastolic filling and blood velocity decrease during the auricular systole.
