title: Serial monitoring of brain natriuretic peptide concentrations for drug therapy management in patients with chronic heart failure.
abstract: Heart failure is a major problem in the Unites States. Despite the availability of and increasing adherence to evidence-based guidelines, the morbidity and mortality from this disease remain significant. Strides have been made in the last several years to develop objective tools to aid in the diagnosis of heart failure and in the prognosis of the affected patients. Brain natriuretic peptide (BNP) and the N-terminal prohormone of BNP are neurohormones released in response to ventricular wall stress and/or tension. As objective laboratory measures, both peptides have similar utility in the treatment of patients with heart failure. Currently, these laboratory tests are approved only to aid in diagnosis. However, data are beginning to emerge that suggest the utility of serial BNP monitoring for the management of chronic heart failure in patients with left ventricular dysfunction. Preliminary studies have shown that when added to traditional management combined with adherence to evidenced-based national guidelines, serial monitoring of BNP levels with adjustment of therapy based on the results may improve outcomes in patients with chronic heart failure compared with traditional clinical management alone. Factors that may limit the use or confound interpretation of the laboratory test results include the effects of demographics (e.g., sex, age, body mass index), concurrent diseases, and drug therapies. Several large, outcomes-based studies are under way to examine the use of serial BNP monitoring to decrease morbidity, mortality, and overall health care costs in patients with heart failure.
