BACKGROUND: Plasma B-type cardiac natriuretic peptides reflect cardiac structure and function and have proven roles in assisting in the diagnosis of acute heart failure. They are independent prognostic indicators across the full spectrum of cardiovascular disease. Serial changes in plasma B-type cardiac natriuretic peptides parallel prognosis in chronic heart failure. Beneficial responses to medications and devices used in the treatment of heart failure are associated with decreases in plasma B-type peptide concentrations. This effect has led to the hypothesis that intensified treatment directed at reducing B-peptide concentrations may improve outcomes in heart failure. CONTENT: The efficacy of serial measurements of plasma B-type peptides in guiding titration of therapy for chronic heart failure has been the subject of several randomized controlled trials reported in the peer-reviewed literature since 2000. These reports are summarized in this review. Trial design, characteristics of the heart-failure population studied, duration of follow-up, exact end points recorded, and target peptide concentrations pursued all differ somewhat between trials. In addition, in studies in which benefits were seen, the exact mechanisms mediating the improvements in outcome were unclear. However, an overall consistency is emerging that is supported by 2 metaanalyses. SUMMARY: In aggregate the existing trial data suggest that adjustment of treatment in chronic heart failure according to serial B-type peptide measurements, used in conjunction with established clinical methods, is likely to reduce cardiac mortality and hospital admissions with heart failure, at least in patients with systolic heart failure who are younger than 75 years and relatively free of comorbidities. |
