On the data of the State Chornobyl Registry of Ukraine (SRU), the dynamics and structure of cardiovascular morbidity were studied in evacuees cohort with regard to sex and age at the time of the accident (1539, 40 years and older). It was done by five-year observation periods (19881992; 19931997; 19982002; 20032009 seven-year period). In persons under investigation there was found the dynamics of growth of cardiovascular morbidity with the highest rates in 19982002. For some forms of pathology (cardiomyopathy, cerebral infarction, diseases of veins, lymphatic vessels and lymph nodes complicated by phlebitis and thrombophlebitis, varicose veins of lower extremities) the highest rates were observed during 20032009. Hypertension (predominantly with heart involvement), ischemic heart disease and cerebrovascular pathology dominate in the structure of cardiovascular morbidity among evacuees. Complications of hypertension, cerebrovascular pathology, diseases of arteries and veins made the most contribution to the structure. Cardiovascular disease was proved to be sex-and age-dependent. In men unlike women, there were recorded higher rates of cardiomyopathy, disease of arteries, arterioles and capillaries, veins, lymph vessels, lymph nodes and their complications. The maximum level of cardiovascular diseases was reported for persons aged over 40. In this age group as compared to evacuees under 40 years, there was observed multiple increase in rates of ischemic heart disease, cerebrovascular diseases, diseases of arteries, arterioles and capillaries and their complications heart attack, stroke, cerebral infarction, atherosclerosis, embolism and arterial thrombosis. Incidence of veins, lymphatic vessels, lymph nodes, complicated by phlebitis, thrombophlebitis and varicose veins of lower extremities was equally high in both age groups under study.

Key words: the Chornobyl accident, circulatory diseases, evacuees, dynamics, structure, sex, age.
