Concentrations of all endothelial markers tested, except PECAM-1, differed between comparison groups of interest; sTM, Angpt-2, Angpt-2/Angpt-1 ratio, Angpt-2/Tie-2 ratio, VCAM-1, and ICAM-1 were higher; Angpt-1 and Tie-2 were lower among those with D3 SA-AKI SCr relative to those without. Here, TEK is linked to acute kidney injury.
