Best Beta Blocker for Heart Failure with Preserved Ejection Fraction in a Patient on Entresto
There is no specific beta blocker that has demonstrated superior efficacy for heart failure with preserved ejection fraction (HFpEF) in patients on Entresto (sacubitril/valsartan), and beta blockers are not routinely recommended as primary therapy for HFpEF unless there are specific comorbid indications.
Beta Blockers in HFpEF
Evidence and Recommendations
According to the 2023 ACC Expert Consensus Decision Pathway on management of HFpEF, beta blockers may be used in HFpEF patients only for specific indications 1:
- Prior myocardial infarction (for up to 3 years)
- Angina
- Atrial fibrillation rate control
Unlike in heart failure with reduced ejection fraction (HFrEF), beta blockers have not demonstrated mortality benefits in HFpEF patients 1
Historical trials of beta blockers in HFpEF have shown negative or neutral results 1
Exercise tolerance should be monitored in HFpEF patients on beta blockers due to the potential for chronotropic incompetence 1
Beta Blocker Selection for Specific Indications
If a beta blocker is indicated for a comorbid condition in a HFpEF patient on Entresto, the following options should be considered:
For rate control in atrial fibrillation:
- Metoprolol succinate (extended-release) - starting at 12.5-25mg daily, target 200mg daily
- Bisoprolol - starting at 1.25mg daily, target 10mg daily
- Carvedilol - starting at 3.125mg twice daily, target 25mg twice daily (for weight <85kg) or 50mg twice daily (for weight ≥85kg)
For post-myocardial infarction or angina:
- Any of the three evidence-based beta blockers (metoprolol succinate, bisoprolol, or carvedilol) can be used 1
Primary Therapies for HFpEF
Instead of focusing on beta blockers, the following medications have demonstrated benefit in HFpEF and should be prioritized:
SGLT2 inhibitors (dapagliflozin or empagliflozin) - shown to reduce hospitalization for heart failure and cardiovascular death in HFpEF patients 1
Mineralocorticoid receptor antagonists (MRAs) like spironolactone - may benefit selected HFpEF patients 1
Entresto (sacubitril/valsartan) - the patient is already on this medication, which has shown some benefit in HFpEF, particularly in patients with LVEF below normal but not reduced enough to be classified as HFrEF 1
Diuretics - for symptom management of congestion 1
Monitoring and Cautions
If a beta blocker is prescribed for a specific indication, monitor for:
- Worsening exercise tolerance
- Bradycardia
- Hypotension
- Fatigue
Start at low doses and titrate slowly in HFpEF patients
Avoid beta blockers in patients with severe reactive airway disease, symptomatic bradycardia, or advanced heart block 1
The combination of Entresto with beta blockers requires careful monitoring of blood pressure, as both can cause hypotension
Conclusion
For a HFpEF patient on Entresto, there is no evidence supporting the routine use of any specific beta blocker for the primary treatment of HFpEF. Beta blockers should only be used for specific comorbid indications, with careful monitoring of exercise tolerance and potential side effects. Focus treatment on optimizing SGLT2 inhibitors, MRAs, and diuretics as needed for symptom management.
