Why the study?
Are levels of beta-human atrial natriuretic peptide-like immunoreactivity increased in human atrial tissue with hemodynamic overload from mitral disease?
Are levels of beta-human atrial natriuretic peptide-like immunoreactivity increased in human atrial tissue with hemodynamic overload from mitral disease?
Hemodynamic overload in the human atrium, such as in mitral disease, is characterized by increased tissue levels of ANP and a shift to the beta-hANP form.
May mark atrial overload in mitral disease; hypothesis-generating and requires prospective validation before any clinical use.
The levels and molecular form of atrial natriuretic peptide-like immunoreactivity (ANP-LI) in human atrial tissue were investigated. The levels of right atrial ANP-LI were significantly higher in mitral disease than in other cardiac or noncardiac diseases. The increased ANP-LI was mainly accounted for by an increase in beta-human ANP-LI (beta-hANP-LI). Both total ANP-LI and beta-hANP-LI levels were associated with the presence of atrial fibrillation and with increased atrial pressure. Plasma beta-hANP-LI levels were also increased in mitral disease. These results suggest that human atrium with hemodynamic overloads is characterized by increased tissue levels of ANP and by a shift to the beta-hANP form.
