Furthermore, fT3 correlated with parameters of PH (HVPG: ρ = -0.300; p <0.001), endothelial dysfunction (von Willebrand factor antigen [VWF]: ρ = -0.357; p <0.001), and hyperdynamic circulation (pro-brain-type natriuretic peptide [proBNP]: ρ = -0.385; p <0.001). This evidence concerns the gene NPPB and endothelial dysfunction.
