To elucidate the synthesis of atrial natriuretic polypeptide (ANP) in the failing heart, eighteen human right auricles obtained at cardiovascular surgery were studied. The concentration of α-human ANP-like immunoreactivity (α-hANP-LI) in human right auricles ranged from 13.8 to 593.5 μg/g, and the tissue α-hANP-LI concentration in severe congestive heart failure (CHF) (New York Heart Association (NYHA) functional class III or IV) was much higher than those in mild CHF of NYHA class I and class II. The α-hANP-LI in the human auricle consisted of 3 major components of ANP, γ-human ANP (γ-hANP), β-human ANP (β-hANP) and α-human ANP (α-hANP). The predominant component of α-hANP-LI was γ-hANP in the mild CHF, whereas β-hANP and/or α-hANP were prevailing in the severe CHF and, especially, β-hANP was markedly increased in human failing hearts.
