The source of someproduced cytokines is epicardial fat tissue (EFT). There is a positive correlation between EFT thickness and metabolic activity. In thisstudy, we aimed to investigate the relationship between oxidative stress and epicardial fat tissue thickness in patients with heartfailure.Material and Methods: A total of 36 patients with heart failure-reduced ejection fraction as study group and 36 subjects withoutheart failure as control group were included in the study. Biochemical blood analyses and echocardiographic examinations wereperformed.Results: The NT-proBNP level in the heart failure-reduced ejection fraction group was significantly higher than the control group(6506.8±11214.3, 116.5±185.6, respectively, p&lt;0.001). The total oxidant status level in the heart failure-reduced ejection fractiongroup was significantly higher than the control group (14.5±3.7, 10.3±2.0, respectively, p&lt;0.001). The total antioxidant capacity levelin the heart failure-reduced ejection fraction group was significantly lower than the control group (7.2±2.8, 14.4±8.7, respectively,p&lt;0.001). The EFT thickness level in the heart failure-reduced ejection fraction group was significantly higher than the control group(0.78 / (0.67-0.85), 0.51 / (0.37-0.66), respectively, p&lt;0.001).Conclusions: Oxidative stress was higher in patients with heart failure and similarly the EFT thickness was found to be increased.</dc:description><dc:date>2020</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/19719</dc:identifier><dc:identifier>https://doi.org/10.5455/annalsmedres.2019.12.839</dc:identifier><dc:language>en</dc:language><dc:relation>Annals of Medical Research</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/19719</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
