Investigators will determine whether N-of-1 trials, as a pragmatic, participant-centered approach to medication optimization that can overcome key barriers of deprescribing, can lead to increased participant confidence regarding their preference to continue or discontinue beta-blockers in older adults with Heart Failure with Preserved Ejection Fraction (HFpEF).
This is an unblinded NIH Stage I of Behavioral Intervention Development trial, using serial multiple-period single participant crossover design. Investigators will enroll 20 participants, conducting an N-of-1 trial in each. The intervention is a two-arm crossover withdrawal/reversal design (On \[A\] vs. Off \[B\]) with up to 6 periods, each period lasting up to 6 weeks. The sequence of treatment will be randomized to either ABAB or BABA. Each participant will have the option to participate in additional (no more than 6) periods if they wish to gather more data. The intervention drug will be be…
Inclusion Criteria: 1. Ambulatory adults age ≥ 65 years with HFpEF, according to ACC/AHA guidelines (signs and symptoms of heart failure AND ejection fraction ≥ 50%) 2. Taking beta-blocker Exclusion Criteria: 1. Alternate cause(s) of HFpEF Syndrome: 1. Severe aortic stenosis 2. Moderate-severe mitral stenosis 3. Constrictive pericarditis 4. High output HF 5. Infiltrative cardiomyopathy 2. Other compelling indication(s) for beta-blocker 1. Prior EF \< 50% 2. Hypertrophic cardiomyopathy 3. Angina 4. Acute coronary syndrome, myocardial infarction, or coronary arter…
The intervention is a two-arm crossover withdrawal/reversal design (On \[A\] vs Off \[B\]) with up to 6 periods, each period lasting up to 6 weeks. During the On period (A), participants will be on their home beta-blocker (or highest tolerable) dose. During the Off period (B), their beta blockers will be down-titrated and subsequently discontinued (or the lowest tolerable dose). Participants will be randomized into either ABAB or BABA sequences. Other names: acebutolol, atenolol, betaxolol, bisoprolol, carvedilol, labetalol, metoprolol, metoprolol succinate, metoprolol tartrate, nadolol, nebivolol, propranolol, penbutolol, pindolol, propranolol
