• Lead Sponsor: Wake Forest University Health Sciences

Brief Summary

The REHAB-HFpEF trial will determine whether a novel physical rehabilitation intervention will improve the primary outcome of combined all-cause rehospitalizations and mortality and the secondary outcome of major mobility disability during 6-month follow-up in patients hospitalized for heart failure and preserved ejection fraction (HFpEF), which is nearly unique to older persons, and for which there are few treatment options.

Detailed Description

REHAB-HFpEF, is a multicenter, randomized, attention-controlled, single-blind trial to examine the hypothesis that, a novel, tailored, progressive, multi-domain physical rehabilitation intervention administered to older patients with acute decompensated heart failure (ADHF) with preserved ejection fraction (HFpEF) beginning early during hospitalization and continuing for 12 weeks in a structured outpatient setting, and continuing as a maintenance program will reduce the rate of combined all-cause rehospitalization and death at 6 months (the primary outcome), and reduce major mobility disability (MMD) prevalence at 6 months (the secondary outcome). This trial, REHAB-HFpEF, builds upon preliminary studies, including the phase 2 REHAB-HF trial, which suggests this intervention may yield significant benefits for this population which are largely older, frail, and with few evidence-based treatment options. Participants will be recruited from 20 clinical centers, each of which may have up to 3 tightly-affiliated 'satellite' sites geographically-close, under their direct management. Together, these centers will recruit a total of 880 consenting patients \>=60 years old hospitalized with ADHF with HFpEF. Following informed consent and baseline testing, the participants will be randomized in a 1:1 fashion to receive a novel, progressive, multi-domain rehabilitation and exercise training intervention or attention control. The intervention will include strength, balance, endurance, and mobility training and the specific training exercises will be tailored based on participant performance in each of these domains. The intervention will begin as soon as possible after randomization during the hospitalization and will continue 3 times per week in an outpatient setting for 12 weeks. Those randomized to the attention control will be contacted bi-weekly by study staff to maintain contact, collect information regarding health status, clinical events, and physical activity/exercise, and ensure retention; they do not receive any specific exercise recommendations. Both arms will receive all services ordered by their primary physician (usual care) and undergo measures of physical function, cognitive function, and quality of life (QOL).

Recruitment & Eligibility

• Status: RECRUITING
• Sex: All
• Target Recruitment: 880

Inclusion Criteria

1. Age >=60 years old

2. Ejection Fraction >=45%

3. In the hospital setting >24 hours for the management of acute decompensated heart failure (ADHF), or diagnosed with ADHF after being hospitalized for another reason. ADHF will be confirmed by the site physician, and will be defined according to the Food and Drug Administration (FDA) definition of hospitalized heart failure as a combination of symptoms, signs, and HF-specific medical treatments, and requires that all 4 of the following are met:

   • At least 1 symptom of HF which has worsened from baseline: a. dyspnea at rest or with exertion; b. exertional fatigue; c. orthopnea; d. paroxysmal nocturnal dyspnea (PND)
   • At least 2 of the following signs of HF: a. Pulmonary congestion or edema on physical exam (rales or crackles) or by chest X-ray; b. Elevated jugular venous pressure or central venous pressure >=10 mm Hg; c. peripheral edema; d. wedge or left ventricular end diastolic pressure >=15 mmHg; e. rapid weight gain (>=5 lbs.); f. Increased b-type natriuretic peptide (BNP) (>=100 pg/ml) or N-terminal prohormone BNP (>=220pg/ml)
   • Change in medical treatment specifically targeting HF, defined as change in dose or initiation of or augmentation of at least 1 of the following therapies: a. diuretics; b. vasodilators; c. other neurohormonal modulating agents, including angiotensinconverting enzyme inhibitors, angiotensin II receptor blockers (with or without neprilysin inhibitor), beta-blockers, aldosterone inhibitors, direct renin inhibitors, or sodium-glucose co-transporter-2 inhibitors
   • The primary cause of symptoms and signs is judged by the investigator to be due to HF

4. Adequate clinical stability to allow participation in study assessments and the intervention Independent with basic activities of daily living, including the ability to ambulate independently (with or without the use of an assistive device) prior to admission

5. Able to walk 4 meters (with or without the use of an assistive device) at the time of enrollment

Exclusion Criteria

1. Acute myocardial infarction within the past 3 months, or planned coronary artery intervention (percutaneous or surgical) within the next 6 months (Note: given that cardiac biomarkers such as troponin are frequently elevated in HF patients, the diagnosis of acute myocardial infarction should be based on clinical diagnosis, not biomarkers alone)
2. Severe aortic or mitral valve stenosis
3. Severe valvular heart disease with planned intervention within next 6 months
4. Known pericardial constriction, genetic hypertrophic cardiomyopathy, or infiltrative cardiomyopathy including amyloid heart disease (amyloidosis)
5. Planned discharge other than to home or a facility where the participant will live independently
6. Terminal illness other than HF with life expectancy <1 year
7. Impairment from stroke or other medical disorders that preclude participation in the intervention
8. Known dementia by medical record documentation, OR patients with Montreal Cognitive Assessment (MoCA) <=18 AND without social support, OR MoCA <10 regardless of social support
9. Advanced chronic kidney disease defined as estimated glomerular filtration rate <20 mL/min/1.73 m2 or on chronic or intermittent dialysis or dialysis anticipated within the next 6 months
10. Already engaging in regular moderate to vigorous exercise conditioning defined as >30 minutes per day, >= twice per week consistently during the previous 6 weeks
11. Enrollment in a clinical trial not approved for co-enrollment
12. High risk for non-adherence as determined by screening evaluation
13. Inability or unwillingness to comply with the study requirements or give consent
