About this study

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).

Read the detailed description

In heart failure (HF) patients, dyspnea (shortness of breath), a key contributor to and the strongest predictor of a chief reason for hospital readmission with fatigue, are the primary reasons for modification in function leading to decreased physical activity (PA). Dyspnea and fatigue lead to activity avoidance, subsequent muscle de-conditioning, and further increases of dyspnea at even lower levels of activity. Depression, because of its moderate relationship both with perceived functional status and dyspnea, can further diminish PA and increase disability in activities of daily living (ADLs). Strategies to minimize or mitigate dyspnea and to boost motivation are imperative for improving adherence to PA, and, in turn, improving fatigue, muscle weakness, PA itself, functional status, disability, and depression in HF patients. Thus, diaphragmatic breathing retraining (DBR) or deep breathing with a slow breathing pattern, a focus on decreasing dyspnea, and mediated by Self-efficacy for DBR and informal caregiver support during the DBR provide an innovative approach to positively impact the spiraling effects of HF. The purpose of this pilot/feasibility study is to evaluate a diaphragmatic breathing retraining (DBR) intervention that incorporates informal caregiver coaching to improve the primary outcomes of dyspnea, fatigue, and muscle weakness, and the secondary outcomes of PA, functional status, depression, disability, and depression.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Diaphragmatic Breathing RetrainingBehavioural

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

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

Secondary outcomes (1)
  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.

    Muscle strength is measured by Nicholas dynamometer (Model 01160, Lafayette Instrument Co., Lafayette, IN). Physical activity is measured by 7-items from Behavioral Risk Factor Surveillance System (BRFSS) (BRFSS, 2009; Kohl \& Kimsey, 2009), ActiHeart (Respironics, Inc.), and ActiGraph (Model GT3X, Pensacola, FL). Functional status is measured by 6-MWT and Timed Get Up \& Go. Disability in ADLs \& IADLs is measured by restriction \& modification in performance of 13 activities composed of basic ADLs (bathing, dressing, feeding, transfer, continence, \& toilet) \& IADLs (shopping, transportation, telephone, preparing meals, housework, taking medication, and handling money) taken from the Older American Resource Services (OARS) tool. Depression is assessed by 21-item Beck Depression Inventory II (Beck et al., 1996) using a 4-point Likert scale. Quality of life is measured by the EuroQol 5-D (EQ-5D; The EuroQol Group, 1990).

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

Questions about this trial

What is this clinical trial studying?

A study testing Diaphragmatic Breathing Retraining in people with Chronic Heart Failure, run by University of Nebraska.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 17 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of deep breathing to control shortness of breath and fatigue by slowing breathing to 6 breaths per minute. (time frame: baseline, after 8 week intervention and 3 months after 8 week intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Oct 2024.
