Core tip: The endothelium is involved in the regulation of vascular tone and permeability, coagulation and fibrinolysis, inflammatory and immunological reactions and cell growth. Cardiovascular risk factors cause vascular endothelial dysfunction through impairing endothelium-derived vasodilators, enhancing endothelium-derived vasoconstrictors, producing reactive oxygen species and reactive nitrogen species, activating inflammatory and immune reactions and promoting thrombosis. Among these mechanisms, a reduction in nitric oxide bioavailability plays a central role in the development and progression of endothelial dysfunction. A variety of currently used or investigational drugs exert endothelial protective effects according to specific mechanisms underlying endothelial dysfunction of the disease.
