title: Brain natriuretic peptide-guided therapy in the inpatient management of decompensated heart failure.
abstract: Heart failure is extremely prevalent and is associated with significant mortality, morbidity and cost. Studies have already established mortality benefit with the use of neurohormonal blockade therapy in systolic failure. Unfortunately, physical signs and symptoms of heart failure lack diagnostic sensitivity and specificity, and medication doses proven to improve mortality in clinical trials are often not achieved. Brain natriuretic peptide (BNP) has proven to be of clinical use in the diagnosis and prognosis of heart failure, and recent efforts have been taken to further elucidate its role in guiding heart failure management. Multiple studies have been conducted on outpatient guided management, and although still controversial, there is a trend towards improved outcomes. Inpatient studies are lacking, but preliminary data suggest various BNP cut-off values, as well as percentage changes in BNP, that could be useful in predicting outcomes and improving mortality. In the future, heart failure management will probably involve an algorithm using clinical assessment and a multibiomarker-guided approach.
