VCAM1 and endothelial dysfunction: Other biomarkers, such as galectin-3 [56], intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and soluble receptor fms-like tyrosine kinase-1 (sFLT-1) [57], leading to stiffness or endothelial dysfunction, are also proposed to be predictive indicators of responders for RDN at baseline.
