Other: HBCR hands-off
Registration Number
NCT06077201
Lead Sponsor
Vanderbilt University Medical Center
Brief Summary

The vast majority of cardiac rehabilitation eligible individuals do not participate in center based cardiac rehabilitation (CBCR). While steps to encourage participation in CBCR are important, many individuals will still not participate for a variety of reasons. This randomized controlled trial is evaluating a home-based cardiac rehabilitation (HBCR) intervention delivered using a custom app and digital tools in patients undergoing transcatheter heart valve interventions (THVIs). After a brief roll-in period, participants not intending to participate in CBCR are randomized to one of three groups: (1) control, (2) HBCR mobile health intervention with hands-off delivery, and (3) HBCR mobile health intervention with interactive delivery. Participants in the intervention groups (hands-off/interactive delivery) will also be randomized to continue the intervention for 12 weeks or 24 weeks. The intervention targets key health behaviors and includes traditional cardiac rehabilitation components. The study will assess the effect of the intervention on clinical events, physical activity, quality of life, and other outcomes. Those who intend to participate in CBCR will be followed in a registry.

Inclusion Criteria
  • Treated with a transcatheter heart valve intervention (e.g., transcatheter aortic valve implantation [in the native valve or valve-in-valve], mitral transcatheter edge-to-edge repair, mitral valve-in-valve) of the aortic, mitral, or tricuspid valve done via transfemoral access
Exclusion Criteria
  • Unwilling or unable to provide informed consent
  • Not adherent to wearing the ActiGraph activity tracker during the roll-in phase for a minimum of 4 (out of 7) compliant days (worn >10 hours/day)
  • Planned participation in center based cardiac rehabilitation (CBCR)
  • Transcatheter heart valve intervention done via any route other than a transfemoral approach
  • Stroke during or immediately after the transcatheter heart valve intervention prior to randomization
  • Placement of a pacemaker within 6 weeks prior to the transcatheter heart valve intervention or after the transcatheter heart valve intervention and prior to randomization
  • Those who require a walker or who cannot get out of a chair/bed on their own and walk independently (use of a cane is acceptable)
  • Physical or neuropsychiatric limitations that would prevent proficient use of the study tools and successful completion of the physical and quality of life assessments (e.g. blindness, dementia)
  • Planned surgery within 6 months after the heart valve intervention
  • Planned discharge from hospital to hospice, assisted living, or inpatient rehabilitation facility (discharge to a senior facility permitted as long as they are considered Independent Living)
  • Treating provider or site PI indicates that participation in the study would be unsafe
  • Participation in any ongoing randomized trial that has not completed follow-up unless the sponsor of the other trial allows enrollment of the participant in this cardiac rehabilitation trial
  • Unable to complete the baseline study visit prior to 6 weeks after the transcatheter heart valve intervention

Primary Outcome Measures
NameTimeMethod
Average daily total activity countsThe actigraphy device will be worn for approximately one week and, using data from days when the device was worn >10 hours, the average daily total activity counts determined. The primary comparison will be at 12 weeks after randomization.

Daily total activity counts are determined by a triaxial actigraphy device.

Probability of the hierarchical clinical event compositeOver the entire available follow-up period for randomized participants (minimum of 6 months, maximum approximately 24-30 months).

The hierarchical clinical event composite includes (in order of hierarchy): (1) all-cause death; (2) all-cause hospitalization; and (3) skilled nursing facility visits. To examine whether the intervention improves mortality, hospitalization, and SNF rates after THVIs, we will conduct Bayesian Markov longitudinal proportional odds model on weekly outcome measures. The pooled active treatment vs. control group comparison (primary comparison for the trial) will be estimated by contrasting the average of posterior probability that Y≥y of the two active treatment groups (hands-off HBCR and interactive HBCR) to the control group.

Secondary Outcome Measures
NameTimeMethod
6 minute walk distanceThe comparisons will be at 12, 24 and 52 weeks after randomization.

The distance walked in 6 minutes.

Heart-failure specific health status assessed by the KCCQThe comparisons will be at 12, 24 and 52 weeks after randomization.

Assessed with the Kansas City Cardiomyopathy Questionnaire (KCCQ); (score range 0-100, higher is better health status)

Average daily total activity countsThe actigraphy device will be worn for approximately one week and, using data from days when the device was worn >10 hours, the average daily total activity counts determined. The secondary comparisons will be at 24 and 52 weeks after randomization.

Daily total activity counts are determined by a triaxial actigraphy device.

All-cause deathOver the entire available follow-up period for randomized participants (minimum of 6 months, maximum approximately 24-30 months).

Death for any cause

Average daily moderate to vigorous active minutesThe actigraphy device will be worn for approximately one week and, using data from days when the device was worn >10 hours, the average daily moderate to vigorous active mins determined. The comparisons will be at 12, 24 and 52 weeks after randomization.

Daily moderate to vigorous active minutes are determined by a triaxial actigraphy device.

Average daily energy expenditureThe actigraphy device will be worn for approximately one week and, using data from days when the device was worn >10 hours, the average daily energy expenditure determined. The comparisons will be at 12, 24 and 52 weeks after randomization.

Daily energy expenditure is determined by a triaxial actigraphy device.

Chair sit to stand timeThe comparisons will be at 12, 24 and 52 weeks after randomization.

The time taken to complete 5 chair rises.

Average daily active minutesThe actigraphy device will be worn for approximately one week and, using data from days when the device was worn >10 hours, the average daily active minutes determined. The comparisons will be at 12, 24 and 52 weeks after randomization.

Average daily stepsThe actigraphy device will be worn for approximately one week and, using data from days when the device was worn >10 hours, the average daily steps determined. The comparisons will be at 12, 24 and 52 weeks after randomization.
