Biochemical parameters of endothelial dysfunction in cardiological syndrome X

Abstract

Endothelial dysfunction in cardiological syndrome X manifests mainly in the regulation of vessel wall tonus. which was revealed by the decrease of NOx level and NOx/ET-1 ratio. VEGF elevation in syndrome X may result from chronic tissue ischaemia due to endothelial dysfunction. Exercise augments the prothrombotic activity of the blood, since a significant elevation in betaTG and decrease in tPA were observed after exercise.
