Clinical Effectiveness of Beta-Blockers in Heart Failure
Key result
Incident beta-blocker use is linked to ~23% lower mortality in elderly patients hospitalized with HFrEF.
- HR 0.77
- 95% CI 0.68-0.87
- n=7,154
Why the study?
Beta-blockers are guideline-recommended for heart failure, but their clinical effectiveness is not well-understood, especially in elderly patients.
Does initiation of beta-blocker therapy reduce mortality and rehospitalization in elderly patients hospitalized for heart failure?
Population
7154 elderly patients hospitalized for heart failure eligible for beta-blockers
Comparison
Newly initiated beta-blocker therapy vs no initiation
Design
Observational linked registry-claims cohort study using inverse probability weighting
Follow-up
1-year

Implication
May support beta-blocker initiation in elderly HF; leaves open confirmation by randomized trials.
Key Points
- This study examines the effectiveness of beta-blocker therapy in reducing mortality and rehospitalization among elderly patients with heart failure.
- Merged Medicare claims data with OPTIMIZE-HF records to evaluate long-term outcomes.
- Analyzed data using inverse probability-weighted Cox proportional hazards models.
- Assessed outcomes among patients newly initiated on beta-blocker therapy.
- 1-year mortality observed at 33% and all-cause rehospitalization at 64%.
- In patients with left ventricular systolic dysfunction, beta-blockers reduced mortality risk (HR 0.77, 95% CI 0.68–0.87).
- In patients with preserved systolic function, beta-blockers had no significant effect on mortality (HR 0.94, 95% CI 0.84–1.07) or rehospitalization.

Does initiation of beta-blocker therapy reduce mortality and rehospitalization in elderly patients hospitalized for heart failure?
P
Population
7,154 elderly patients hospitalized with heart failure and eligible for beta-blockers, evaluated for long-term outcomes.
E
Exposure
Initiation of beta-blocker therapy
C
Comparator
No initiation of beta-blocker therapy (analyzed using inverse probability-weighted models)

Outcome
Mortality, rehospitalization, and a combined mortality-rehospitalization endpointcomposite
Main Result
Hazard Ratio: 0.77 (95% CI 0.68–0.87)
Initiation of beta-blockers in elderly patients hospitalized with heart failure reduces mortality and rehospitalization in those with reduced ejection fraction (LVSD) but not in those with preserved ejection fraction.
Cite This Study
Hernandez et al. (2009) conducted a cohort in heart failure (n=7,154). Beta-blocker therapy vs. No beta-blocker therapy was evaluated on mortality (HR 0.77, 95% CI 0.68-0.87). Among elderly patients hospitalized with heart failure and left ventricular systolic dysfunction, incident beta-blocker use was associated with lower mortality (HR 0.77; 95% CI 0.68-0.87).
