Abstract     The vascular endothelium is an important regulatory organ in maintaining cardiovascular bomeostasis. Endothelial dysfunction, which is predominantly caused by decrease of NO bioactivity, occurs early in the course of atherosclerosis in response to cardiovascular risk factors (hypertension, hypercholesterolemia, diabetes). Disturbances of the vasomotor function of the epicardial conductance arteries are fundamental abnormalities of coronary blood flow in atherogenesis, and impaired endothelial vasodilation is the predominant mechanism underlying inappropriate-paradoxical vasoconstriction. However, endothelial dysfunction may also extend to the coronary microcirculation. With respect to the clinical presentation of coronary artery disease, endothelial vasodilator dysfunction appears to play a causative role in triggering of myocardial ischemia in stable angina pectoris, to aggravate sequelae of acute ischaemic syndrome and might be the primary underlying mechanism in some patients with syndrome X. Further, in this article therapeutic interventions for improvement of the endothelial dysfunction are discussed.
