title: [Natriuretic peptides. History of discovery, chemical structure, mechanism of action and the removal routes. Basis of diagnostic and therapeutic use].
abstract: Natriuretic peptides (NP) are the group of proteins synthesized and secreted by the mammalian heart. All the NP are synthesized from prohormones and have 17-amino acid cyclic structures containing two cysteine residues linked by internal disulphide bond. They are characterized by a wide range of actions, mainly through their membrane receptors. The NP regulate the water and electrolyte balance, blood pressure through their diuretic, natriuretic, and relaxating the vascular smooth muscles effects. They also affect the endocrine system and the nervous system. The neurohormonal regulation of blood circulation results are mainly based on antagonism with renin--angiotensin--aldosterone system. The NP representatives are: atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), C-type natriuretic peptide (CNP), urodilatine and (DNP) Dendroaspis natriuretic peptide, not found in the human body. According to the guidelines of the European Society of Cardiology determination of NT-proBNP level have found a use in the diagnosis of acute and chronic heart failure, risk stratification in acute coronary syndromes and pulmonary embolism. There are reports found in the literature, that demonstrate the usefulness of NT-proBNP determination in valvular, atrial fibrillation, and syncopes. Recombinant human ANP--Carperitid and BNP--Nesiritid, have already found a use in the adjunctive therapy of dyspnea in acute heart failure.
