HEART Camp: Promoting Adherence to Exercise in Patients With Heart Failure
This trial is active, not recruiting.
|Treatments||standard care exercise group, heart camp exercise group|
|Sponsor||University of Nebraska|
|Collaborator||National Heart, Lung, and Blood Institute (NHLBI)|
|Start date||April 2012|
|End date||December 2016|
|Trial size||246 participants|
|Trial identifier||NCT01658670, 1R01HL112979, 608-11-FB|
The purpose of this study is to determine the efficacy of the Heart Failure Exercise and Resistance Training (HEART) Camp behavioral exercise training intervention on long-term adherence to exercise at 18 months in patients with heart failure. The central hypothesis is that the HEART Camp intervention group (HC) will have significantly better adherence to exercise at 18 months.

|Description||The objective of this prospective randomized two-group repeated measures experimental design is to determine the efficacy of the HEART (Heart Failure Exercise and Resistance Training) Camp behavioral exercise training intervention on long-term adherence to exercise at 18 months in patients with HF. A sample size of 246 subjects with heart failure will be recruited over a 3 year period. All subjects will receive a cardiopulmonary exercise test and 9 supervised exercise training sessions during a 3 week run-in period prior to randomization. Subjects completing 6 of 9 training sessions will be randomized to the HEART Camp Intervention group (HC) or to a standard care (SC) exercise group. The HC intervention group will receive cognitive-behavioral strategies that address the intervention components of knowledge, attitudes, self-efficacy, behavioral self-management skills and social support. The SC group is provided access to the exercise facility and regular facility staff for the 18 month study period. Our central hypothesis is that the HC group will have significantly better adherence to exercise at 18 months. We will test our hypothesis with the following Specific Aims: Aim 1. To evaluate the effect of HEART Camp on adherence to exercise (measured by accelerometry and self-report); Aim 2. To evaluate which components of the HEART Camp intervention mediate the effects of the intervention on adherence; Aim 3. To evaluate the effect of HEART Camp on specific health outcomes; Aim 4. To explore selected demographic variables (race, gender, age) as potential moderators of the effect of the HEART Camp intervention on adherence; and Aim 5. To explore the perceptions and experiences that contextualize exercise adherence.|
