Primary objective
Our overall objective is to test the feasibility of an evidence-based intervention prior to evaluation in a future randomised control trial (RCT).Information will be collected on:

  1. The number of patients screened, eligible and approached.

  2. The percentage of patients that:

    1. decline CR (including reasons for declining)

    2. agree to CR and

    3. consent to being part of the study

  3. The percentage of patients that take up standard CR and reasons for drop out; and

  4. the percentage of participants that complete outcome assessments and reasons for drop out.

1–4) Ongoing throughout the intervention
Secondary objective
1. Estimate precision of potential outcome measures required for sample size estimations for the definitive RCT.Six potential outcome measures will be assessed:
1. Adherence to exercise

  1. Adherence to structured exercise

  2. Pre and postintervention exercise questionnaire (GLTEQ)

  3. Objectively assessed physical activity


2. Body composition

  1. Height+weight

  2. Waist circumference


3. Blood pressure
4. Blood lipids and HbA1c

  1. Total cholesterol

  2. HDL/LDL

  3. Triglycerides

  4. HbA1c


5. Health-related quality of life

  1. MacNew Heart disease health-related quality of life

  2. The Behavioural Regulation in Exercise Questionnaire

  3. Patient Rapport with Counsellor Questionnaire

  1. Ongoing throughout the intervention

  2. During initial and outcome assessments

  3. 7 days post CR

2–5) During initial and outcome assessments
2. Evaluate the acceptability of the intervention to patients, assessing the feasibility of implementing the intervention.

  1. Post-intervention patient qualitative data (semi-structured interviews) investigating:

    1. The acceptability of the intervention components and barriers and facilitators to the intervention

    2. Acceptability of the recruitment and randomisation process

    3. Acceptability of the measurement instruments

Post CR (Purposive sampled subset)
3. Determine availability and completeness of economic data

  1. Level EQ-5D

  2. Questionnaire assessing healthcare usage in the last 12 weeks

1–2) Post CR

  • CR, cardiac rehabilitation; EQ-5D, EuroQol Quality of life; HbA1c, Hemoglobin A1c; HDL, High density lipoprotein; LDL, Low density lipoprotein.
