Review Meta AnalysisB-type natriuretic peptide-guided versus symptom-guided therapy in outpatients with chronic heart failure: a systematic review with meta-analysis.
It has been asserted that serial measurements of natriuretic peptides, specifically B-type natriuretic peptide (BNP) or the amino-terminal fragment of pro-B-type natriuretic peptide (NT-proBNP), may serve as an objective practical guide to better tailor the drug treatment for patients with chronic heart failure (CHF), and especially to detect the cases of subclinical congestion that would require an increase in drug dosing. However, considerable uncertainty remains about the alleged useful role of natriuretic peptide-guided therapy in this context. Therefore, we decided to execute a meta-analysis of published randomized controlled trials (RCTs) to test the hypothesis that an improvement of clinical outcomes in outpatients with CHF may be achieved by adjustment of pharmacologic dosing performed according to natriuretic peptide determinations. ⋯ This meta-analysis supports the hypothesis that natriuretic peptide-guided therapy is superior to symptom-guided therapy for improving clinical outcomes in CHF outpatients. However, some large RCTs failed to document significant clinical improvement in terms of mortality and morbidity using a natriuretic peptide-guided strategy; thus, any attempt to clarify this still unresolved issue by means of further basic and clinical research is recommended in the future.
