Natriuretic peptides play a central role in cardiovascular, endocrine, and renal homeostasis and can be considered physiologic antagonists to the renin-angiotensin-aldosterone system. ANP and BNP in the circulation are derived primarily from the myocardium, whereas CNP is mainly derived from endothelial cells and the central nervous system. Increased ventricular and atrial diastolic wall stretch augment synthesis and release of BNP and NT-proBNP from cardiomyocytes, and is the principal stimulus controlling BNP production. Circulating BNP and NT-proBNP levels are increased in heart failure in proportion to disease severity, but elevated levels may also be observed in other cardiac and noncardiac disease states, including cardiac arrhythmias, ventricular hypertrophy, myocardial ischemia, pulmonary embolism, acute and chronic cor pulmonale, renal failure, anemia, hyperthyroidism, and sepsis. Fully automated analyses of both BNP and NT-proBNP can be rapidly performed on large hospital-based platforms as well as on small point-of-care devices.

Natriuretic peptides are peptide hormones which are involved in the regulation of blood pressure, water-mineral balance and multiple metabolic processes. The beginning of research on this group of hormones starts in 1981, when the deBold and collaborators discovered ANP. Eight natriuretic peptides have been described so far: ANP, BNP, CNP, DNP, urodilatin, uroguanylin, osteocrin, musculin and three receptors: NPR-A, NPR-B and NPR-C thanks to which these hormones accomplish their physiological functions. Determination of natriuretic peptide concentration in plasma is used in the diagnosis and treatment of heart failure and pulmonary embolism. Research results indicate that the determination of natriuretic peptides concentration in plasma may also be important in the acute coronary syndromes, subclinical complications of hypertension and atrial fibrillation. The concentration of natriuretic peptides is changing in many diseases. The beneficial effects of natriuretic peptides have led to the production of drugs that are their synthetic derivatives. These drugs are mainly used among patients with heart failure. Research is currently underway on the efficacy and safety of other synthetic natriuretic peptides.
