Anemia is prevalent in patients with chronic heart failure, the proportion of which increases with deteriorating New York Heart Association functional class. Anemia is also associated with increased symptoms, more frequent hospitalizations, and, in some studies, with an increased mortality rate. We have demonstrated that N-terminal brain natriuretic peptide (NT-proBNP) is a powerful predictor of death in advanced heart failure and is superior to the traditional markers of chronic heart failure (CHF) severity. However, to date, there are no published data that compare the prognostic ability of NT-proBNP with that of hemoglobin and hematocrit in patients with advanced heart failure who are referred for consideration of cardiac transplantation at a time when erythropoietin is under investigation as a treatment option in such a population. ⋯ A single measurement of NT-proBNP in patients with advanced CHF can help to identify patients who are at a higher risk of death and is a better prognostic marker than anemia.

The role of brain natriuretic peptides in the detection of mild forms of isolated diastolic dysfunction is still uncertain. We therefore investigated the plasma levels of the N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with heart failure symptoms during exercise, despite preserved systolic cardiac function. ⋯ NT-proBNP levels are increased in patients with increased filling pressures during exercise and useful for the detection of diastolic dysfunction in patients with exertional dyspnea.

Randomized Controlled Trial Multicenter Study Clinical Trial
Randomized trial of a nurse-administered, telephone-based disease management program for patients with heart failure.
Heart failure is a common and important cause of morbidity and mortality. Disease management offers promise in reducing the need for hospitalization and improving quality of life for heart failure patients, but experimental data on the efficacy of such programs are limited. ⋯ A nurse-administered, telephone-based disease management program delayed subsequent health care encounters, but had minimal impact on other outcomes.

N-terminal brain natriuretic peptide (NT-proBNP) improves emergency room diagnosis of acutely decompensated heart failure. Less evidence is available on the usefulness of NT-proBNP as a prognostic marker after hospitalization for acute heart failure. The percentage of NT-proBNP reduction during admission and its prognostic significance were studied. ⋯ NT-proBNP reduction percentage during admission for acutely decompensated heart failure appeared to be the best predictor of cardiovascular death during the follow-up period. A <30% NT-proBNP reduction percentage identified a subgroup of high-risk patients.

Limited data exist regarding the impact of left ventricular ejection fraction (LVEF) on N-terminal pro-brain natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP) levels in patients with acute congestive heart failure (CHF). ⋯ Levels of both NT-proBNP and BNP are significantly lower in patients with NS-CHF; however, in contrast to NT-proBNP, BNP may be falsely negative in up to 20% of patients with NS-CHF and does not correlate with symptom severity in NS-CHF. NT-proBNP appears superior to BNP for the evaluation of suspected acute CHF in patients with preserved LVEF.
