MORTALITY FROM ACQUIRED HEART DISEASE DURING A 15 YEAR PERIOD IN THE RUSSIAN FEDERATION AND THE UNITED STATES AND AN ANALYSIS OF THE FACTORS INFLUENCING THEIR FORMATION
Objective. To provide the comparative analysis of standardized mortality coefficients (SMC) of rheumatic and nonrheumatic mitral (MV) and aortic valve (AV) disorders in 15 years among adults over 30 in the RF and in the USA. Material and methods. The analysis was performed in patients at the age of 30-49, and 50 and older for men and women separately. European standard population data in 2013 was used for mortality coefficients standardization. RF mortality rates were calculated on data of Federal State Statistics Service (1999-2013); USA rates - World Health Organization Mortality Database and Human Mortality Database (2000-2014). Results. Summary SMC for MV and AV disorders at the age of 30-49 years was higher in RF comparing to USA (men - 1.8 and 0.6; women - 0.9 and 0.5 per 100 000 population), in the group over 50 years it was lower in RF comparing to USA (men - 9.9 and 26.5; women - 10.9 and 23.4). SMC of rheumatic disorders decreased significantly in RF during 15 years of analysis. SMC did-n’t changed in USA and were more than 2 times lower comparing to RF in 2013. SMC of nonrheumatic MV and AV disorders were stable and significantly higher in USA at the age over 50 comparing to RF. The rates of SMC of nonrheumatic AV disorders in the mortality structure in men and women over 50 were 80.2 and 71.8% in USA and 25.1 and 13.1% in RF correspondingly. In spite of certain decrease in 15 years SMC of multiform valve disorders were significantly higher in RF (from 2.5 to 6.7 times in 2013 in different investigated groups). Conclusion. There were significant differences in the mortality rates and structures from valves disorders in RF and USA. The essential decrease of SMC from rheumatic valve disorders in RF was registered. These differences were based on peculiarities of disease determination, health care organization, primary death’ cause detection and medical death certificates filling in.
