About this trial
The primary research objective of the project is to determine the role of eGC in microvascular reactivity in patients with coronary heart disease (CHD) before and after bypass grafting (cross-sectional study 2).The main objective of the project is to increase the excellence and interdisciplinarity of scientific work at MEFOS by connecting researchers from different scientific fields, improving conditions and resources for scientific work, and increasing international cooperation, in line with strategic objective 1: raising scientific excellence. The results of the project could provide pathophysiological insight into the development and maintenance of endothelial dysfunction in CVD, as well as identify new biomarkers for CVD.

Trial groups
Trial outcomes
Primary outcomes
Endothelial glycocalyx
Measurement of the thickness of endothelial glycocalyx in coronary heart disease patients before and after bypass surgery - measured by Glycocheck
Secondary outcomes
Bypass graft sample reactivity
Determine the reactivity of the bypass graft sample in in vitro experiments - measured by isolated vessel setup
Endothelial glycocalyx soluble markers
Quantification of soluble markers of endothelial glycocalyx from serum or plasma samples in the specified groups - measured by ELISA assays (syndecan-1, syndecan-4, glypican-1, MMP-9)
Intracellular oxidative stress production
Quantification of intracellular oxidative stress production from peripheral blood mononuclear cells (PBMC) in the specified groups - measured by flow cytometry (DCF-DA and DHE)
Inflammation
Quantification of inflammation from peripheral blood mononuclear cells (PBMC) in the specified groups - measured by Luminex assay (cytokine profile) and flow cytometry (macrophage frequency)
Other outcomes
Blood pressure
Automatic oscillometric measurement of systolic and diastolic blood measurement (mmHg)
Heart rate
Automatic oscillometric measurement of heart rate (bpm)
Body Mass Index
Measurement of BMI (kg/m2)
Body composition
Body composition and body fluid status measurement by a four-terminal portable impedance analyzer. Based on the value of skin resistance (Ohm) empirically derived formulas (the original manufacturer's software) will be used to calculate the estimated Fat Free Mass (FFM kg) and Fat (Fat Mass kg).
