Atherosclerosis
Endothelial dysfunction is thought to be a key event in the development of atherosclerosis and predates clinically obvious vascular pathology by many years. This is because endothelial dysfunction is associated with reduced anticoagulant properties as well as increased adhesion molecule expression, chemokine and other cytokine release, and reactive oxygen species production from the endothelium, all of which play important roles in the development of atherosclerosis.
In fact, endothelial dysfunction has been shown to be of prognostic significance in predicting vascular events including stroke and heart attacks. Because of this, endothelial function testing may have great potential prognostic value for the detection of cardiovascular disease, but currently the available tests are too difficult, expensive, and/or variable for routine clinical use.
