NCT01886391

Brief Summary

The purpose of this study is to provide information on how the practicing of deep breathing ("DBR" - diaphragmatic breathing re-training) may improve the health outcomes and likelihood of heart failure patients to engage in health-promoting activities by successfully controlling their shortness of breath (dyspnea).

Outcome Measures

Primary Outcomes (1)

  • Effect of deep breathing to control shortness of breath and fatigue by slowing breathing to 6 breaths per minute.

    Dyspnea is measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ) and by 18 items of dyspnea from activities composed of basic activities of daily living (ADLs), instrumental activities of daily living (IADLs), and other activities related to physical functioning using a 10-point Liker scale. Fatigue will be measured by 8-items from the PROMIS-57 Profile v.10.

    baseline, after 8 week intervention and 3 months after 8 week intervention

Secondary Outcomes (1)

  • Effect of deep breathing on the secondary outcomes of muscle strength, physical activity, functional status, disability in activities of daily living, and instrumental activities daily living, depression, and quality of life.

    baseline, after 8 week intervention and 3 months after 8 week intervention

Study Arms (1)

Diaphragmatic Breathing Retraining

EXPERIMENTAL

Diaphragmatic breathing retraining (DBR) with a slow breathing pattern such that breathe in slowly through the nose for 4 seconds and breathe out slowly through the mouth for 6 seconds and mediated by Self-efficacy for DBR. Patients in this group will receive detailed instructions, in-person, as to how to carry out the DBR intervention at home. They will provide a return demonstration to the research staff about how to do the deep breathing. They will also receive a written script of the DBR intervention. In addition to the script, patients in this group will receive 3 audio CDs (1 for week 1 \[5-min DBR\], 1 for week 2 \[10-min DBR\], 1 for weeks 3-8 \[15-min DBR\]), developed by the PI, to use to practice their deep breathing.
