About this study

Comprehensive, hybrid cardiac rehabilitation (CR) models have been scantly investigated in heart failure (HF) populations, particularly in low-resource settings.

A 2 parallel-arm, multi-center randomized clinical superiority trial will be conducted with blinded outcome assessment. 152 HF patients (NYHA class II or III) will be recruited consecutively, and randomly assigned. The experimental intervention will include evaluation, medical and nurse management, aerobic interval training, resistance exercise, psychosocial support, and education. These will initially be delivered in a center, transitioning to home in 4 stages. Participants in the control arm will receive face-to-face continuous aerobic exercise sessions and resistance exercises. The main outcomes are cardiorespiratory fitness, functional capacity, and quality of life. These will be measured at baseline, end of intervention, and 12-month follow-up.

The pragmatic, comprehensive hybrid CR model could be implemented more broadly if superiority is demonstrated.

  • Atrial fibrillation with a heart rate greater than 90 beats per minute at rest.
  • Active neoplasm with life expectancy <2 years.
  • Inclusion in another interventional study.
  • Explicit contraindications to performing exercise.
  • Comorbidities that preclude the patient from engaging in a CR program.
  • Musculoskeletal or neurological disease that precludes the patient from performing exercise.

Treatment and study plan

Comprehensive Initial Assessment

Other

Initial Assessment includes all those necessary to prescribe exercise training, as well as dietary and adherence promotion interventions.

  • Functional capacity with 6MWT
  • Assessment of skeletal muscle strength, flexibility, and balance.
  • Assessment of function
  • Assessment of dietary habits
  • Assessment of self-efficacy and barriers to CR adherence.
  • Screening for depression.

Continuous evaluation

Other

Evaluations during the course of the program will be carried out to inform the progression through the CR stages, the intensity of training and education needs.

Interval Exercise

Other

High-intensity interval training prescribed by physical therapist:

  • According to an adapted Wisloff protocol.
  • Borg scale to monitor intensity.
  • Training 3 times per week.

Psychosocial support

Behavioral

Based on social-cognitive theory, with self-efficacy as a focus:

  • Face-to-face sessions in the first stage of the program: Education, self-monitoring and motivational interview.
  • Face-to-face session in the second stage of the program: promoting behavior changes by self-control and self-monitoring
  • Regular communication with patients will be supported by the use of mobile devices during the third and fourth stages of program.

Diet management

Other

A dietary plan supported by a nutritionist will be made together with the patient.

Resistance Exercise

Other

Resistance exercises:

  • With TheraBand.
  • Intensity according to the perceived exertion scale
  • Twice a week.

Continuous exercise

Other

Moderate-intensity continuous exercise prescribed by physical therapist :

  • The intensity will be moderate, as tolerated
  • Borg scale to monitor intensity.
  • Frequency of training of 1 to 3 times per week, until completed 20 sessions in 10-12 weeks.

Initial Assessment

Other

Includes all those necessary to plan exercise training, as usual:

  • Functional capacity with 6MWT.
  • Assessment of skeletal muscle strength.

Primary outcomes

  1. Cardiorespiratory fitness

    Time frame: Baseline, 6 months and 12 months.

    Will be assessed during a symptom-limited cardiopulmonary exercise test using an individualized gradual incremental ramp test designed to obtain oxygen consumption (VO2max).

  2. Functional capacity

    Time frame: Baseline, 6 months and 12 months.

    Will be assessed by the six-minute walk test (6MWT)

  3. Health Related Quality of Life

    Time frame: Baseline, 6 months and 12 months.

    Will be evaluated with the Minnesota Living with Heart Failure Questionnaire (MLHFQ). This questionnaire has 21 questions, which are answered on a scale of 1 to 5. The score of the questionnaire is obtained by the sum of the answers to the 21 questions, the higher the score, the worse the quality of life.

Secondary outcomes

  1. Program adherence and completion

    Time frame: 6 months

    Program adherence is defined as the percentage of total prescribed sessions completed. For home-based activities, the percentage of activities carried out at home of the prescribed ones will be computed.

  2. Concentration of Pro-B-type Natriuretic Peptide

    Time frame: Baseline, 6 months and 12 months.

    Biomarker with prognostic utility. When it is higher than 1000 pg/mL, there is a higher probability of having events such as hospitalizations.

  3. Functioning

    Time frame: Baseline, 6 months and 12 months.

    Defined as the ability to perform basic, instrumental and advanced activities of daily living. It will be measured with the Activities of Daily Living Questionnaire - Technology (ADLQ-T). This questionnaire evaluates 7 areas: self-care (6 items), home care and management (6 items), work and recreation (4 items), shopping and money (3 items), travel (3), communication (5 items) and technology (5 items). Each item has a score, where 0 is no problem for the activity up to 3 indicating that he/she cannot perform the activity. The functional deficit is calculated for each area and for the overall questionnaire with the sum of all scores, divided by 3 and then multiplied by the total number of items answered. A higher score indicates greater impairment of ADLs.

  4. Mortality and Hospital admission

    Time frame: 12 months

    Will be measured as a composite outcome. It will be measured as a composite outcome. An adjudicating committee will confirm the events that will be expressed as the number of participants hospitalized or dead and their respective causes. All-cause and HF-specific mortality and hospitalization will be differentiated.

  5. Upper-body muscle strength

    Time frame: Baseline, 6 months and 12 months.

    Will be assessed through grip strength performed with a Jamar® Plus+ electronic handheld dynamometer. the result shall be expressed in kilograms.

  6. Lower-body muscle strength

    Time frame: Baseline, 6 months and 12 months.

    Will be assessed through the chair stand test, with the participant in a seated position in a chair. From this position, they will be directed to rise fully and return to the starting position as many times as possible over 30 seconds. The number of repetitions achieved will be recorded

  7. Cost

    Time frame: 6 months

    Will be assessed through micro-costing from the health care system perspective. Also out-of-pocket spending by patients will be costed
