Pilot Deprescribing N-of-1 Trials for Beta-blockers in HFpEF
Heart Failure, Heart Failure, Diastolic, Heart Failure With Preserved Ejection Fraction
About this trial
This is an interventional other trial for Heart Failure
Eligibility Criteria
Inclusion Criteria:
- Ambulatory adults ≥65 years of age with Heart Failure with Preserved Ejection Fraction (HFpEF) according to ACC/AHA guidelines: (signs and symptoms of Heart failure [HF] and ejection fraction [EF] ≥50%)
- Taking Beta blocker
Exclusion Criteria:
Alternate Causes of HFpEF Syndrome:
- Severe valvular disease
- Constrictive pericarditis
- High output heart failure
- Infiltrative cardiomyopathy
Other compelling indication for beta blocker:
- Prior EF < 50%
- Hypertrophic cardiomyopathy
- Angina symptoms
- Acute coronary syndrome, myocardial infarction or coronary artery bypass surgery in prior 3 year
- History of ventricular tachycardia
- Atrial arrhythmia with hospitalization for rapid ventricular response, prior 1 year
- Sinus tachycardia > 100 beats per minute (bpm), atrial arrhythmia with ventricular rate >90 bpm, systolic blood pressure > 160 mmHg
Clinical instability (N-of-1 trials are appropriate for stable conditions only)
- Decompensated HF
- Hospitalized in past 30 days
- Medication changes or procedures in prior 14 days (to prevent confounding from other interventions), at PI discretion
- Estimated life expectancy <6 months
- Moderate-severe dementia or psychiatric disorder precluding informed consent
- Any condition that, in Principal Investigator's opinion, makes the patient unsuitable for study participation

Beta Blocker ABAB Sequence
Beta Blocker BABA Sequence
This arm will follow an ABAB sequence. "A" representing ON beta blockers and "B" representing OFF beta blockers. Subjects in this arm will continue their home dose during the initial A period, they will then crossover into Period 2, where dose reduction will begin until they are off of beta blockers. During Period 3, they will restart beta-blockers, gradually uptitrating until reaching their home dose and finally during period 4, we will again conduct a dose reduction until off of beta blockers.
This arm will follow a BABA sequence. "A" representing ON beta blockers and "B" representing OFF of beta blockers. Subjects in this arm will have their previously prescribed beta blocker dose reduced until they are completely off of beta blockers during Period 1. They will then crossover into Period 2, where uptitration will begin until they are back on their previously prescribed dose of beta blockers. During Period 3, we will again conduct a dose reduction, until the subject is off of beta blockers and finally during Period 4, we will uptitrate them back to their home dose of beta blockers.
