Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the addition of high-intensity interval training to the standard pre-heart transplantation clinical care. Participants will be randomised into 2 arms: one arm will receive high-intensity interval training, and the other arm will be encouraged to remain physically active, although they do not participate in a regular structured exercise training program.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Heart failure affects more than 6.2 million people living in North America. Approximately 10% of patients with heart failure have advanced heart failure. Heart transplantation is an effective life-saving treatment for patients with advanced heart failure. The cardiovascular rehabilitation programs are integral to heart failure management.

This study is being done to evaluate, in adults with advanced heart failure awaiting heart transplantation, the effects of cardiovascular rehabilitation (including high-intensity interval training, stress management and nutrition workshops) on functional capacity, aerobic power, frailty, quality of life, and mental health.

This study compares pre-transplant cardiovascular rehabilitation with usual pre-transplant care in patients with advanced heart failure awaiting heart transplant.

All participants will be randomized into 2 study groups: Group 1 (rehab), and Group 2 (no rehab). Those randomized to Group 1 will receive usual care, 12 weeks of rehab (exercise training, and attend stress and nutrition course through the Heart Failure Clinic and the Division of Prevention and Rehabilitation at the University of Ottawa Heart Institute). Those randomized to Group 2 will receive regular visits through the Heart Failure Clinic; patients are encouraged to remain physically active, although they do not participate in a regular structured exercise training program.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Interventional

Group 1. Usual care + High-Intensity Interval Training, Nutritional Workshop, Stress Management Course.

Group Type EXPERIMENTAL

High-Intensity Interval Training

Intervention Type BEHAVIORAL

Participants will complete supervised exercise sessions. Participants will attend on-site high-intensity interval training two times weekly for 12 weeks. Participants will complete six-minute walk test, cardiopulmonary exercise test, and six questionnaires: Short Form 36 Health Survey Questionnaire (SF-36), Minnesota Living with Heart Failure Questionnaire (MLHFQ), Beck Depression Inventory II (BDI-II), Beck Anxiety Inventory (BAI), Montreal Cognitive Assessment (MOCA), and Impact of Events Scale-Revised (IES-R) at baseline (week 1) and follow-up (after 12 weeks of intervention).

Non interventional

Group 2. Usual care. Patients are encouraged to remain physically active, although they do not participate in a regular structured exercise training program.

Group Type NO_INTERVENTION

No interventions assigned to this group
