Endothelin (ET)-1, a 21-amino acid peptide, represents the major isoform of the endothelin peptide family, which further includes ET-2, ET-3, and ET-4.1 It is the most potent vasoconstrictor known and stimulates cell proliferation in various tissues. The biologically inactive precursor big ET is converted to the mature peptide by the endothelin-converting-enzyme. ETAreceptors, which lead to increased intracellular calcium concentrations, induce vasoconstriction and cell proliferation. ETBreceptors which mediate the release of NO and prostacyclin cause vasodilatation and are involved in the clearance of ET-1 and in the inhibition of the endothelin-converting-enzyme.

In atherosclerosis, the production of ET-1 is stimulated and both tissue and plasma ET-1 levels are positively correlated with the extent of atherosclerosis.1 Moreover, in patients with coronaryartery
