Clinical assessment of endothelial function.
The endothelium is crucial in the maintenance of normal vascular function and disturbance of this balance is a key early event in the development of vascular disease. A wide range of techniques currently exists for assessment of endothelial function in both the coronary and the peripheral vasculature. Many of these in vivo tests have concentrated on measuring nitric oxide bioavailability, however more recently methods for measuring other vascular parameters, such as tissue-plasminogen activator release, have been used. Furthermore indirect systemic measurements of endothelial function and endothelial progenitor cells have been investigated. These methods have given great insights into the pathophysiology of atherosclerosis and have aided in the development of a number of antiatherosclerotic therapies. Importantly the methods used to date for assessing endothelial function in vivo are accurate, reproducible and correlate with the future risk of cardiovascular events. The development of new techniques and the constant refinement of established techniques suggest that many more insights are to be gained from clinical assessment of endothelial function.
