Research Abstract |
Plasma levels of endothelin (ET) -1 and atrial natriuretic peptide (ANP) increase with the progression and the severity of congestive heart failure (CHF). ET-1 mediates vasoconstriction and myocardial hypertrophy. We demonstrated that high plasma ET-1 patients with CHF had a poor prognosis, suggesting the important role of ET-1 in CHF.As ANP inhibits ET-1 secretion in vitro, we evaluated whether endogenous ANP inhibit the ET-1 secretion in dogs with CHF by using specific ANP receptor antagonist (HS 142-1). Our recent finding indicates that endogenous ANP directly inhibits endogenous ET-1 secretion through a cGMP-mediated path way in CHF.
