Brief Summary

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

In this study, It is aimed to evaluate the effect of breathing exercise on fatigue in patients with heart failure, to reduce the severity of fatigue in participants, and thus to enable patients to participate more actively in daily life.

Detailed Description

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

In the Heart Failure Prevalence and Indicators study in Turkey, the prevalence of heart failure (HF) in the adult population was determined as 3.2%. In line with this study, although Turkey has a young population, it is seen that the prevalence of HF is higher than in western countries. As it is known, fatigue is one of the most characteristic symptoms of HF and it was determined that the perceived fatigue was moderate or severe in 92% of the patients. There is a decrease in the activities of daily living of patients with fatigue and their quality of life is adversely affected. For this reason, nurses have an active role in the evaluation of fatigue and in ensuring that the patient can cope with fatigue with appropriate interventions. In the management of fatigue, non-pharmacological approaches are frequently used in addition to current pharmacological treatment. Breathing exercises, one of the non-pharmacological approaches used; consists of breathing control and exercises that create body awareness. It also controls the instincts and the mind. In a study conducted with patients with multiple sclerosis; Upper extremity exercise and breathing exercises were combined as a home-based program, 2 days a week in 60-minute sessions. It has been demonstrated that the 4-week program contributes to the reduction of fatigue. However; A study reported to be the first to evaluate the effects of yoga and specific breathing techniques for improving cardiovascular function, autonomic system, and quality of life in heart failure patients with preserved ejection fraction is still in the patient selection and intervention stages. In this study, the participants were randomly divided into three groups, and active breathing techniques were applied to the first group and passive breathing techniques to the second group. The third group (control) receives standard pharmacological treatment. The application period is done in 45-minute sessions twice a week for 8 weeks. There is no study in the literature investigating the effect of breathing exercise on fatigue in patients with heart failure. In this study, which was planned in the light of this information; It is aimed to evaluate the effect of breathing exercise on fatigue in patients with heart failure, to reduce the severity of fatigue in patients, and thus to enable patients to participate more actively in daily life.

Heart Failure Fatigue

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Patients willing to participate in the study are evaluated according to the inclusion and exclusion criteria. Afterwards, they are divided into 3 groups with the stratified sampling method. The intervention group is given face-to-face breathing exercises under the supervision of the trainer, through video calls over the WhatsApp application after discharge. The placebo group is asked to breathe normally through the nose with eyes closed, sitting in the same position as the intervention group, under the supervision of the trainer. Venous oxygen saturation, heart rate/minute and respiratory rate/minute are monitored by pulse oximetry given to the participants in the intervention and placebo groups before and after each session for 8 weeks. The severity of fatigue of the participants in all groups; It is measured before starting the application, in the middle of the application period (4th week) and after the application is completed (8th week).

Study Groups

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

Breathing Exercise Group

This group will be given breathing exercises in accordance with the determined protocol.

Group Type ACTIVE_COMPARATOR

Breathing exercise

Intervention Type OTHER

Following the protocol prepared, the breathing exercise group is given breathing exercises for about 20 minutes, 3 times a week for 8 weeks, under the supervision of the trainer, in the hospital face-to-face, and after discharge through video calls over the WhatsApp application. Reminders (by text message or voice call) are used for the remaining 4 days of the week, allowing the patient to do it on their own.

Placebo Breathing Group

Normal breathing of this group will be monitored.

Group Type PLACEBO_COMPARATOR

Placebo Breathing Group

Intervention Type OTHER

The placebo group is asked to breathe normally through the nose with eyes closed, sitting in the same position as the intervention group for 10-15 minutes, 3 times a week for 8 weeks, under the supervision of the trainer, in the hospital face-to-face, and after discharge through video calls over the WhatsApp application.

Control Group

No application will be made to this group.
