BACKGROUND: Studies with natriuretic peptides have suggested that physicians do not treat heart acute failure (AHF) aggressively enough, and predischarge B-type natriuretic peptide (BNP) levels may be a useful reminder that more treatment is required. The purpose of this study was to demonstrate that variations in BNP levels during hormone-guided treatment and measured body hydration status enable the timing of the patient's discharge to be optimized. METHODS AND RESULTS: We retrospectively evaluated 186 patients admitted for AHF. All subjects underwent serial bioelectrical impedance analysis and BNP measurement. Therapy was titrated according to BNP value to reach a BNP value of <250 pg/mL, whenever is possible. A BNP value on discharge of <250 pg/mL (obtained in 54% of the patients) predicted a 16% event rate within 6 months, whereas a value >250 pg/mL was associated with a far higher percentage (78%) of adverse events. Among the former, no significant differences in event rate were seen in relation to the time necessary to obtain a reduction in BNP values below 250 pg/mL (14 versus 18%, chi-square = 0.3, NS). Cox regression showed that a BNP cutoff value of 250 pg/mL is the most accurate predictors of events. CONCLUSIONS: Our study demonstrates the usefulness of BNP in intrahospital stratification of AHF, in the decision-making process, and as a tool for "tailored therapy." Integrating this approach into the routine assessment of HF patients would allow clinicians to more accurately identify high-risk patients, who may derive increased benefit from intensive in-hospital management strategies.
