Several studies have shown that endothelial function assessed by biomarkers for endothelial function including circulating levels of nitrate/nitrite, NO, von Willebrand factor (vWF), cellular adhesion molecules, vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1), endothelial progenitor cells (EPCs) and endothelial microparticles (EMPs), endothelin-1 and activity of endothelial NOS (eNOS) other than physiological assessment for endothelial function was impaired in smokers
