B-Type Natriuretic Peptide-Guided Treatment for Heart Failure

BNP or NT-proBNP guided treatment may reduce heart failure admissions compared to treatment of heart failure guided by clinical assessment alone. Level of evidence: "C"

The quality of evidence is downgraded by study limitations (lack of blinding) and by inconsistency (variability in results).

Summary

A Cochrane review [Abstract] 1 included 18 studies with a total of 3 660 adult subjects. BNP or NT-proBNP (collectively referred to as NP) guided treatment of heart failure was compared with treatment guided by clinical assessment alone. Heart failure hospital admissions were reduced by NP-guided treatment, but there was uncertainty for all-cause admissions.No statistically significant difference in all-cause mortality or heart failure mortality were observed although the point estimates favoured NP-guided treatment.Six studies (n=1 144) reported on adverse events, but the results could not be pooled. Only 4 studies (n=1 051) provided cost of treatment results, 3 of these studies reported a lower cost for NP-guided treatment, whilst 1 reported a higher cost. The evidence showed uncertainty for quality of life data (MD -0.03, 95% CI -1.18 to 1.13, statistical heterogeneity I2 =75%; 8 studies, n=1 812).
