The results of epidemiologic researches in European countries and USA demonstrated that the prevalence of chronic heart failure (CHF) varies within 0,4-2,5 %. The aim of research –an assessment of clinical features of CHF and structural-functional changes in the heart on the background of overweight and obesity in patients of the different age groups. Methods . It was examined 300 patients of the different age groups with CHF of 1-111 functional class (FC) on the background of overweight and abdominal obesity of 1-111 degree. Depending on division of indicators there was used an unpaired Student t-criterion or Mann-Whitney U-criterion. Results . In examined patients with overweight and obesity CHF progress with age that declares itself by FC increase and of body mass index (BMI) decrease. The clinical course of CHF in elder age is characterized by the spread of the permanent form of atrial fibrillation. With age CHF of combined etiology is more often. The structural changes in the heart at CHF in elder patients are characterized by the more significant dilatation of the left atrial and hypertrophy of the left ventricle of concentric type. The clinical course of CHF in elder age is characterized by an increase of frequency of systolic dysfunction of the left ventricle and formation of the lung hypertension. Conclusions : It was established that in examined patients with CHF on the background of an overweight and obesity with age took place an increase of FC of disease, the prevalence of CHF of combined etiology and decrease of BMI. In elder patients with CHF it were observed the more apparent spread of the permanent form of atrial fibrillation and the dilatation of the left atrial and hypertrophy of myocardium of concentric type. Functional changes in the heart in examined patients of an elder age group are characterized by the more frequent systolic dysfunctio ns of the left ventricle and formation of the lung hypertension.
