Mortality rates due to diseases of the circulatory system in Karachay-Cherkess republic in 2006 and 2014

Aim. To study mortality rates due to diseases of the circulatory system and certain nosological forms in Karachay-Cherkess Republic in 2006 and 2014.

Methods. The data of the Russian Federation Federal State Statistics Service on the number of deaths according to a short nomenclature of causes of deaths were analyzed. The nosological structure was studied, proportion of each of the causes of death in the total number of deaths from circulatory system diseases was defined. The names of groups of short nomenclature of causes of deaths in 2006 and 2014 were compared. Non-standardized and standardized mortality rates were calculated.

Results. Standardized mortality rate due to circulatory diseases decreased by 29.3% in 2014 in comparison with 2006. The decline in mortality due to circulatory system diseases was noted in all age groups, except for the age group 25-29 years (+18.5%) and 60-64 years (+4.2%). Deaths due to primary and recurrent myocardial infarction decreased (by 46.2%) in all age groups except the age of 40-44 years and 80-84 years, in which the mortality rate due to primary and recurrent myocardial infarction increased by 12.5 and 49.4%, respectively. The mortality from ischemic heart disease increased in age 35-39 years (by 11.3%) and 40-44 years (39.4%). In other age groups, the mortality from ischemic heart disease decreased, the maximum reduction was reported in age 65-69 years (54.8%). Standardized mortality rate due to cerebrovascular diseases decreased by 44.06% in 2014 in comparison with 2006.

Conclusion. Taking into account significant contribution to the mortality structure due to circulatory system diseases number of deaths, causes of which are not clearly classified and cause problems with clinical interpretation, this issue requires attention of cardiologists, in terms of both health care delivery and specification of the patients’ health status.
