Levels of soluble cellular adhesion molecules are increased in patients with atherosclerosis, and have been found to predict coronary heart disease. Therefore these molecules have been suggested to represent laboratory markers for inflammation and activation of endothelial cells. Impaired endothelium-dependent vasodilation has been demonstrated to be an early marker of atherosclerosis. ⋯ Thus, in hypercholesterolaemic patients without clinical atherosclerosis, levels of soluble adhesion molecules were not elevated in comparison with healthy controls. In addition, these markers of endothelial inflammation were not related to impaired endothelium-dependent vasodilation. Our data indicate that measurement of levels of soluble adhesion molecules cannot replace assessment of endothelium-dependent vasodilation in detection of early hypercholesterolaemic atherosclerosis.
