Effect of B-type natriuretic peptide-guided treatment of chronic heart failure on total mortality and hospitalization: an individual patient meta-analysis
Key result
Natriuretic peptide-guided treatment of heart failure significantly reduced all-cause mortality compared to clinically guided care (HR 0.62; 95% CI 0.45-0.86; P=0.004).

Implication
Supports natriuretic peptide-guided therapy to reduce mortality in chronic HF; confirms benefit across randomized trials.
Key Points
- To assess the impact of natriuretic peptide-guided treatment on all-cause mortality in chronic heart failure.
- Conducted an individual patient meta-analysis of 11 randomized clinical trials
- Included 2000 patients with individual data for analysis
- Used Cox proportional hazards regression to evaluate outcomes.
- NP-guided treatment reduced all-cause mortality (HR=0.62; 95% CI 0.45-0.86; P=0.004)
- Reduced heart failure hospitalization (HR=0.80; 95% CI 0.67-0.94; P=0.009)
- Reduced cardiovascular disease hospitalization (HR=0.82; 95% CI 0.67-0.99; P=0.048)

Main Result
Hazard Ratio: 0.62 (95% CI 0.45–0.86)
p-value: p=0.004
Natriuretic peptide-guided treatment of heart failure reduces all-cause mortality in patients aged <75 years and overall reduces heart failure and cardiovascular hospitalizations.
Cite This Study
Troughton et al. (2014) conducted a meta-analysis in chronic heart failure (n=2,000). Natriuretic peptide-guided treatment vs. standard clinically guided care was evaluated on all-cause mortality (HR 0.62, 95% CI 0.45-0.86, p=0.004). Natriuretic peptide-guided treatment of heart failure significantly reduced all-cause mortality compared to clinically guided care (HR 0.62; 95% CI 0.45-0.86; P=0.004).
