Obesity and its associated comorbidities increase the risk of mortality. The development of subclinical inflammation associated with obesity also plays a significant role in this. In our work, we focused on changes in the endocrine and mitochondrial function of adipose tissue and their relationship to cardiovascular complications. The first part of the thesis focuses on determining the expression of mitochondrial and endoplasmic reticulum genes in epicardial and subcutaneous adipose tissue, intercostal muscle or right myocardial atrium in patients with atherosclerotic coronary artery disease. Patients with coronary artery disease had reduced expression of several mitochondrial chain genes in epicardial adipose tissue compared to subcutaneous adipose tissue and other tissues, while no change in endoplasmic reticulum gene expression in the above-mentioned tissues has been demonstrated. Based on decreased mitochondrial gene expression in patients with coronary artery disease, we conclude that mitochondrial dysfunction of epicardial adipose tissue may contribute to the development of coronary atherosclerosis. The second part of the thesis is focused on neudesin, new potentional regulator of energy metabolism, in obese patients with type 2 diabetes mellitus (T2DM), who underwent various weight reduction...
