Popis: Aim. To study the relationship between serum levels of aldosterone, tissue inhibitor of matrix metalloproteinases-1 (TIMP-1), tumor necrosis factor-alpha (TNF-) and structural and functional changes in the heart during the progression of chronic heart failure (CHF) with a moderately reduced ejection fraction (CHFunEF) in patients with type 2 diabetes mellitus (DM). Material and methods. 58 patients were examined 30 (51.7%) men and 28 (48.3%) women diagnosed with DM and CHFunEF (EF=4149%), with functional class (FC) I, II and III of CHF according to New York Heart Association (NYHA). The control group consisted of 16 people. Patients underwent echocardiography, determination of serum levels of aldosterone, TIMP-1 and TNF- by ELISA. The patients were divided into 2 groups: 1st group patients with DM and CHFunEF who had a myocardial infarction (MI) 27 people (46.6%), 2nd group patients with DM and CHFunEF 31 people (53.4%). Statistica v. 10.0 software (USA) was used for statistical analysis. Differences were considered statistically significant at р0.05. Results. Serum levels of aldosterone, TIMP-1 and TNF- were significantly higher than those of the control group and increased with an increase in CHF FC. In patients of the 1st group, the volume and index values of the left parts of the heart and serum levels of biomarkers significantly exceeded those of the 2nd group. Conclusion. Activation of the aldosterone system, increased profibrotic and immuno-inflammatory processes with the progression of CHFunEF in patients with DM lead to an increase in serum levels of aldosterone, TIMP-1 and TNF- with an increase in CHF FC. Patients with DM and CHFunEF who have undergone MI have more pronounced structural and functional changes in the heart and greater values of volumetric and index parameters of the left heart than patients with DM and CHFunEF. Serum levels of aldosterone, TIMP-1 and TNF- in patients with DM and CHFunEF who have undergone MI exceed those in patients with DM and CHFunEF, these biomarkers can be used to diagnose the progression of CHFunEF in patients with DM.
