Study summary

Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure for older adults with severe symptomatic aortic stenosis who are considered high risk for surgical aortic valve replacement. Despite symptomatic and survival benefits, many patients experience functional decline after TAVR. This pilot study aims to test the feasibility of a home-based exercise intervention targeting endurance, strength, and balance as well as cognitive behavioral intervention to improve physical functioning and disability after TAVR.

Read the detailed description

We hypothesize that a home-based exercise program with cognitive behavioral intervention is more effective than home-based exercise alone; home-based exercise program with and without cognitive behavioral intervention is more effective than attention control educational intervention in preventing decline in physical function and disability after TAVR.

Interventions

  • BehavioralExercise

    Exercises will target balance, flexibility, strength, and endurance (source: https://go4life.nia.nih.gov/). Home visits will take place twice a week for week 1 and 2; once a week for week 3 and 4; every other week for week for week 5 through week 8. Participants are instructed to do prescribed exercises for 30 minutes daily. The duration of this intervention is about 40 mins.

  • BehavioralCognitive behavioral interventions

    The following cognitive-behavioral strategies will be employed: 1) enhance positive beliefs about exercise through discussion of benefits of exercise; 2) discussion of barriers to exercise; 3) individualized goal setting and self-monitoring progress using exercise calendar; 4) develop a detailed exercise plan on how, what, when, and where to conduct exercise; 5) $10 rewards for exercising ≥30 mins per day for ≥5 of 7 days. The duration of this intervention is about 20 mins.

  • BehavioralAttention control education program

    A health care professional will call the participant weekly for a period of 8 weeks to teach general tips about exercise and diet (source: https://go4life.nia.nih.gov/). No recommendations for a specific exercise program will be made, except for walking 30 minutes daily or as tolerated. Each telephone session will cover 4 exercise tips and 4 healthy eating tips. The duration of the intervention is about 30 minutes.

What researchers measure

Primary outcomes

  1. Change in the Late-Life Function and Disability Instrument (LLFDI) Score

    The LLFDI is a validated patient-reported outcome questionnaire that measures both functional limitations (inability to perform physical tasks - Activity Limitation Domain score, range: 0-100) and disability (inability to perform major life tasks and social roles - Participation Restriction Domain score, range: 0-100). For both scales, higher values indicate better function (lower limitation or lower disability). Two domain scores are analyzed separately.

    Time frame: At baseline and week 8

Secondary outcomes

  1. Change in the Short Physical Performance Battery (SPPB) Summary Score

    The summary score is calculated based on chair stands, walking speed, and standing balance (range: 0-12). Higher scores indicate better physical performance.

    Time frame: At baseline and week 8

  2. Change in the 2-Minute Walk Distance (Feet)

    The 2-minute walk distance measures endurance. A longer distance indicates better endurance.

    Time frame: At baseline and week 8

  3. Change in Dominant Hand Grip Strength (kg)

    Dominant hand grip strength measures upper extremity strength.

    Time frame: At baseline and week 8

  4. Number of Participants Who Experienced Adverse Events

    Number of participants who experience any adverse events and serious adverse events

    Time frame: At week 8

Other outcomes

  1. Change in Mini-Mental State Examination (MMSE) Score

    MMSE is an instrument that assesses general cognitive function (range: 0 to 30). Higher scores indicate better cognitive function.

    Time frame: At baseline and week 8

  2. Change in New York Heart Association (NYHA) Functional Class

    NYHA assesses the extent of physical activity limitation due to heart failure. It ranges from 1 (ordinary physical activity does not cause symptoms) to 4 (symptoms occur at rest).

    Time frame: At baseline and week 8

  3. Change in the Self-Efficacy Scale for Exercise (SEE)

    The SEE scale measures self-efficacy about exercise (range: 0-90). Higher values indicate higher self efficacy.

    Time frame: At baseline and week 8

  4. Change in the Outcome Expectation Scale for Exercise (OEE)

    The OEE scale measures outcome expectation about exercise (range: 9-45). Higher scores indicate higher expectation.

    Time frame: At baseline and week 8

  5. Adherence to the Home-based Exercise Program

    The proportion of days with completed daily task during the entire study period will be measured.

    Time frame: At week 8

Limitations and caveats
The primary outcome measure instrument, LLFDI Computer Adaptive Test software for Windows, could not be run after Windows operating system update during the study period. The software was not maintained by the developer to keep up with the latest version of the operating system. As a result, LLFDI measure was not measured for most participants at 8 weeks. The investigators measured a disability score (22 daily activities and physical tasks), which is highly correlated with LLFDI scores.

Participant flow

Between August 2017 and February 2020, 64 patients were enrolled from the Beth Israel Deaconess Medical Center and the Brigham and Women's Hospital in Boston, MA.

Post-hocDisability Score

The disability score measures the count of 22 daily activities and physical tasks that a person cannot perform without another person's help. It ranges from 0 to 22. Higher values indicate severe disability. Its correlation with LLFDI was -0.76 against the Activity Limitation Domain score and -0.65 against the Participation Restriction Domain score.
