lmportance of epicardial fat in heart diseases: new mechanism of action and their therapeutic implication
Matloch, Zdeněk ; Haluzík, Martin (advisor) ; Maruna, Pavel (referee) ; Lipš, Michal (referee)
It was documented earlier that epicardial fat is a source of pro-inflammatory mediators under basal conditions (Mazurek, Zhang et al. 2003, Baker, Silva et al. 2006). It was also found that during cardiac surgery there is an increased expression of mRNA for pro- inflammatory cytokines in both epicardial and subcutaneous adipose tissue (Kremen, Dolinkova et al. 2006). During advanced heart failure, an inflammation of adipose tissue and resistance to adiponectin was also discovered (Khan, Kato et al. 2012). As part of the project, we tested the hypothesis that changes in levels of pro-inflammatory and anti-inflammatory cytokines, including their expression in adipose, muscle and heart tissue, as well as changes in insulin resistance and lipid profile parameters, are dependent on the type of underlying disease of patients, either the presence of CAD or valve degeneration. The aim of our project was to investigate metabolic changes in various fat tissues, insulin resistance, pro-inflammatory and anti-inflammatory cytokines plasmatic levels and their mRNA expressions in patients with coronary artery disease (CAD) undergoing either elective coronary artery bypass surgery (CABG) or isolated valve replacement. Our patients underwent several blood tests and measurements like anthropometric, biochemical, and...
