چکیده انگلیسی
Endothelin-1 (ET-1) is a short chained peptide primarily of endothelial origin. Concentrations of this peptide are increased in subjects with hypertension, primary pulmonary hypertension and myocardial infarction, however its short half-life makes quantification difficult. The C-terminal of proET-1 (CTproET-1) is stoichiometrically secreted with its bioactive peptide and would be a valid method of measuring the active peptide as it has a stable half-life and is less resistant to proteolytic cleavage. The objective of this study was to understand the factors (clinical, echocardiographic and biochemical) that specifically influence plasma CTproET-1 in healthy subjects. 518 healthy volunteers were recruited from a screening study. Plasma CTproET-1 concentrations were quantified using a novel immunoluminometric sandwich assay. In multivariate analyses, age (PÂ <Â 0.001), diastolic BP (PÂ =Â 0.007), LA size (PÂ =Â 0.001) and eGFR (PÂ <Â 0.001) were independently predictive of plasma CTproET-1 levels in the healthy subjects. Therefore the interpretation of plasma CTproET-1 levels in such individuals should take into account these variables to avoid potential confounding.
