Endothelial Function

Endothelial function refers to the ability of the thin layer of cells called the endothelium that lines the inside of blood vessels to regulate blood flow, maintain blood vessel tone, and control the exchange of substances between the bloodstream and surrounding tissues. Healthy endothelial function involves the release of substances that promote blood vessel relaxation or constriction as needed, preventing blood clotting, inflammation, and the buildup of plaque. Impaired endothelial function, often caused by various risk factors, can lead to endothelial dysfunction, increasing the risk of cardiovascular diseases such as hypertension and atherosclerosis. Maintaining a healthy endothelium is important for overall cardiovascular health and can be influenced by lifestyle factors and managing chronic conditions.
