Activity

  • Function:  May function as a paracrine antifibrotic factor in the heart. Also plays a key role in cardiovascular homeostasis through natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion.
  • Mechanism:  Plasma levels of natriuretic peptides B, brain natriuretic peptide 32 and NT-proBNP are widely used for screening and diagnosis of heart failure (HF), as these markers are typically higher in patients with severe HF.
