What is the Meaning of Endothelial Function?

Endothelial Function refers to the physiological capability of the endothelium, the single-cell layer lining the interior of blood vessels, to regulate vascular tone, coagulation, and inflammation. Optimal function is characterized by robust production of vasodilators, particularly nitric oxide (NO), and minimal pro-thrombotic or pro-inflammatory states. Impaired endothelial function is an early and sensitive marker for cardiovascular risk, often preceding overt hypertension. This function is highly sensitive to hormonal status and metabolic stress.

What is the Origin of Endothelial Function?

The concept evolved from cardiovascular research, where the endothelium was recognized as an active endocrine organ rather than just a passive barrier. "Endothelial" refers to the cells lining the vessel lumen, and "function" denotes their active regulatory roles. Understanding its importance connects vascular health directly to systemic physiological regulation.

What is the Mechanism of Endothelial Function?

Endothelial cells produce nitric oxide synthase (eNOS), which generates NO, causing smooth muscle relaxation and vasodilation, thus lowering SVR. This process is influenced by sex hormones; estrogen generally supports eNOS activity. Conversely, oxidative stress and chronic inflammation diminish NO bioavailability, leading to endothelial dysfunction, increased SVR, and elevated blood pressure.
