Brief Summary

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

The heart failure syndrome that occurs when the heart is too sick to properly do its job. One of the main symptoms is difficulty with exercise. One way to improve symptoms is to start patients in a 12 week exercise program called cardiac rehabilitation. Cardiac rehabilitation been shown to improve symptoms for heart failure patients. However, the investigators do not know exactly what exercise does to the molecules that make up the human body. If the investigators could answer this question, the investigators might find a whole new way to treat the symptoms of heart failure. Therefore the investigators want to know what molecules might be responsible for the benefits of exercise. The plan for this study is to measure the levels of thousands of proteins in blood samples which come from people with heart failure and see how those levels change after 12 weeks of cardiac rehabilitation, compared to the protein levels in patients whose cardiac rehabilitation is delayed until after the study period. If the investigators know the proteins that change with exercise, the investigators can then look to see if targeting these proteins with medicines can mimic the benefits of exercise. The long term goal of our work is to identify "exercise-in-a-pill" medicines that will help people with heart failure.

Study Groups

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

Active arm: Acute exercise + 12 weeks Cardiac Rehabilitation

This arm includes two-thirds of enrollees and focuses on both acute and chronic effects of exercise. Qualifying participants with heart failure randomized to this arm will undergo a 40 minute bout of moderate intensity exercise on a date prior to beginning in cardiac rehabilitation. Blood samples will be collected before and after the acute bout at 10, 30, and 210 minutes after exercise. Participants will then go to cardiac rehabilitation for a 12 week period. A single blood sample will be obtained at 6 weeks. The participants will return after the 12 weeks of cardiac rehabilitation for a second bout of acute exercise and blood sampling identical to the first. Finally, 12 weeks after completion of cardiac rehab, patients will return for another single blood sample.

Group Type EXPERIMENTAL

Acute exercise

Intervention Type BEHAVIORAL

40 minute moderate intensity exercise bout on a treadmill. This is similar to a single session of cardiac rehabilitation.

Cardiac rehabilitation

Intervention Type BEHAVIORAL

12 week program of standard clinical cardiac rehabilitation for patients with symptomatic heart failure. Patients undergo 3-times weekly sessions of monitored exercise for 12 weeks. This is the same cardiac rehabilitation patients would get as part of clinical care.

Control arm: No exercise

This arm includes one-third of enrollees and serves as control. Qualifying participants with heart failure randomized to this arm will begine with a 40 minute period of rest on a date prior to beginning in cardiac rehabilitation. Blood samples will be collected before and after the the 40 minute period at 10, 30, and 210 minutes after exercise. Participants will then defer cardiac rehabilitation for a 12 week period. A single blood sample will be obtained at 6 weeks of this control intervention period. The participants will return after the 12 weeks of control intervention for an actual bout of acute exercise and blood sampling identical to those completed by the active arm. They will then enter cardiac rehabilitation as per standard of care. Finally, 12 weeks after completion of cardiac rehab, patients will return for another single blood sample.
