Beyond their established role as heart failure biomarkers, natriuretic peptides (ANP and BNP) have direct therapeutic potential through their vasodilatory, diuretic, and hormone-suppressing actions.
Dual potentialNatriuretic peptides work as both diagnostic biomarkers and direct therapeutic agents for heart failure — a rare dual clinical utility
What the researchers found
Natriuretic peptides have dual clinical potential: as diagnostic/prognostic biomarkers for heart failure and as direct therapeutic agents through vasodilation, diuresis, and suppression of the renin-angiotensin and sympathetic nervous systems.
Why it matters
This review captured the moment when natriuretic peptides were transitioning from research curiosities to clinical tools — both as blood tests and potential treatments. Both applications have since become clinical reality.
How the study worked
Comprehensive review of natriuretic peptide biology, diagnostic applications, and therapeutic potential in heart failure, covering ANP, BNP, and CNP.
What this study cannot tell us
Review from 1999; some therapeutic applications described were still in early development. Long-term outcomes of natriuretic peptide therapy were not yet established.
How to read the evidence
Strong evidence from a comprehensive review synthesizing diagnostic, prognostic, and therapeutic studies of natriuretic peptides.
When this study was published
Published in 1999. Both diagnostic (BNP/NT-proBNP testing) and therapeutic (nesiritide, sacubitril/valsartan) applications are now established clinical practice.
The bigger picture
The vision described in this review has largely been realized: BNP testing is standard diagnostic practice, and nesiritide (synthetic BNP) was approved for acute heart failure treatment, while neprilysin inhibitors that boost endogenous natriuretic peptides are now cornerstone heart failure therapy.
Questions still open
- Can natriuretic peptide therapy improve long-term heart failure survival?
- Which patients benefit most from natriuretic peptide augmentation?
- Could chronic natriuretic peptide boosting replace current heart failure medications?
Common questions
Can natriuretic peptides treat heart failure, not just diagnose it?
What's the difference between ANP, BNP, and CNP?
