Diseases of the circulatory system in the Kyrgyz Republic in the period of 2002–2017

Aim To analyze a tendency in circulatory system diseases (CSD) in the Kyrgyz Republic (KR).
Materials and methods Medical statistics on morbidity, prevalence, mortality, and primary disability related with CSD in the adult population was obtained from the National Health Information Center (NHIC) of the Ministry of Health of the KR and the National Statistical Committee of the KR. For the purpose of comparative analysis, relative values were calculated per 100,000 and 10,000 population. A retrospective epidemiological study of prevalence, morbidity, mortality, and primary disability related with CSD for 2002-2017 was performed with calculation of the increase/decrease rate using the least square method for aligning the dynamic row. Also, the epidemiological situation of CSD was analyzed by sex and in 9 administrative divisions of the KR with calculation of the mean long-term incidence (MLTI) of CSD from 2007 through 2017. Statistical analysis was performed with specialized Statistica 10.0 and SPSS 11.5 software.
Results CSD remain the major cause of death (51.6 % in 2017) and primary disability (19.68 % of overall primary disability) in the Kyrgyz population. Prevalence of CSD shows a pronounced upward trend (6.8% increment rate relative to 2002) whereas the incidence rate has increased with a moderate trend (3.5 % increment rate). The major structure of CSD is determined by essential hypertension (51.2 %), ischemic heart disease (28.0 %), and cerebrovascular diseases (10.0 %). CSD is more frequently observed in women (mean value for 2007-2017, 59.0%) than in men (41.0 %) (р<0.001). Mean long-term indexes of CSD significantly differ in different regions and cities of the KR. The highest primary morbidity and prevalence of CSD is observed in Bishkek (1546.90 / 0000 and 12415.40 / 0000). Relatively low levels of these values are found in the Talas Region (720.70 / 0000 and 3675.10 / 0000, respectively).
Conclusion CSD remains the major cause of death and primary disability in the population of the KR. Prevalence of CSD shows a pronounced increasing trend whereas the increase in incidence rate is moderate. The major structure of CSD is determined by essential hypertension, ischemic heart disease, and cerebrovascular diseases. Incidence of CSD is statistically significantly higher for women than for men. Mean long-term indexes of CSD significantly differ in different regions and cities of the KR. Therefore, it is essential to enhance preventive measures in the KR; to identify individuals with hypertension at the level of primary care; and to motivate healthcare professionals to improve the quality of healthcare (CSD prevention, detection, and treatment).
