Prevalence of arterial hypotension with a poor prognosis in populations of the Russian Federation and the United States of America

Aim. To study the prevalence of hypotension (HoTN) with an unfavorable prognosis in populations of the Russian Federation and the United States of America in a thirty-year perspective.Material and methods. We used data from Russian population-based studies performed in 1975-1982 at the now-familiar National Medical Research Center for Therapy and Preventive Medicine, and the study Epidemiology of Cardiovascular Diseases and their Risk Factors in Regions of Russian Federation (ESSE-RF) in 2012-2014. A comparison was made with data from studies of US population of the National Health and Nutrition Examination Survey (NHANES): NHANES II (1976-1980) and Continuous NHANES (2007-2012). Age, sex, systolic and diastolic blood pressure were analyzed. The proportion of persons with HoTN (prevalence) was calculated in men and women of five age groups using the original HoTN criterion. Results. We used the previously developed criterion of HoTN with an unfavorable prognosis: for Russian populations, the mean dynamic pressure is
