Beta-Blocker Replacement in Heart Failure with Reduced Ejection Fraction
Evidence-Based Alternatives
- The American College of Cardiology and American Heart Association recommend replacing bisoprolol with either carvedilol or sustained-release metoprolol succinate in patients with heart failure with reduced ejection fraction (HFrEF), as these are the only other beta-blockers with proven mortality reduction in this population 1, 2
- The American College of Cardiology recommends bisoprolol (target dose 10 mg once daily) as one of the three beta-blockers that have demonstrated mortality reduction in large-scale trials for HFrEF 3
- The American College of Cardiology recommends metoprolol succinate (sustained-release) (target dose 200 mg once daily) as one of the three beta-blockers that have demonstrated mortality reduction in large-scale trials for HFrEF 4
Specific Replacement Strategies
- For patients with HFrEF, the American College of Cardiology recommends starting carvedilol at 3.125 mg twice daily and titrating every 2 weeks to a target dose of 25 mg twice daily (or 50 mg twice daily if ≥85 kg), with a 65% mortality reduction shown in the US Carvedilol Heart Failure Program and 35% reduction in the COPERNICUS trial for advanced heart failure 3, 7
- For patients with HFrEF, the American College of Cardiology recommends starting metoprolol succinate (sustained-release) at 12.5-25 mg once daily and titrating every 2 weeks to a target dose of 200 mg once daily, with a 34% reduction in all-cause mortality demonstrated in the MERIT-HF trial 3, 5
- For patients with post-myocardial infarction and left ventricular systolic dysfunction (EF ≤40%), the American College of Cardiology recommends using carvedilol or metoprolol succinate, and continuing beta-blocker therapy for at least 3 years in all patients with normal left ventricular function after myocardial infarction or acute coronary syndrome 2
Practical Switching Protocol
- When switching from bisoprolol to another beta-blocker, the American Heart Association recommends starting the replacement beta-blocker at a low initial dose while tapering bisoprolol, with carvedilol started at 3.125 mg twice daily and metoprolol succinate started at 12.5-25 mg once daily 3, 7, 5
- The American Heart Association recommends titrating the replacement beta-blocker gradually every 2 weeks to the target dose if tolerated, with monitoring for bradycardia, hypotension, worsening heart failure symptoms, and fluid retention 6, 9, 10
Dose Equivalency Reference
- The American College of Cardiology provides approximate equivalent doses to bisoprolol 5 mg, including metoprolol succinate 50-100 mg once daily and carvedilol 12.5 mg twice daily 8
- The American College of Cardiology recommends target doses for HFrEF, including bisoprolol 10 mg once daily, carvedilol 25 mg twice daily (<85 kg) or 50 mg twice daily (≥85 kg), and metoprolol succinate 200 mg once daily 4, 9, 10
Special Populations Requiring Dose Adjustment
- For patients with renal impairment, the American College of Cardiology recommends dose adjustments, including a maximum of 50 mg daily for atenolol with creatinine clearance 15-35 mL/min and a maximum of 25 mg daily for creatinine clearance <15 mL/min 9
- For elderly patients, the American College of Cardiology recommends starting at the lower end of the dosing range, assessing renal function before initiating therapy, and titrating more cautiously 6, 9
