Andningsstyrketräning hos hjärttransplanterade
Inverkan av preoperativ respiratorisk styrketräning på postoperativ hälsa för hjärttransplanterade mottagare
This research study is investigating whether completing breathing exercises before surgery helps heart transplant patients recover after surgery. Previous studies have shown that breathing exercises can improve breathing, cough, and swallow function in patients with other diseases/conditions. The current study will investigate the impact of a preoperative respiratory muscle strength training program on breathing and cough function, swallow function, patient-reported eating and swallowing fatigue, and health outcomes in individuals undergoing heart transplantation.
Participants will:
- undergo tests of breathing, cough, and swallow function
- complete questionnaires about the treatment, their swallow function
- complete breathing exercises daily

Detaljerad beskrivning
This study will involve three in-person research evaluations to our lab or in the hospital that will last 45 minutes- 1 hour and will consist of a screening, breathing and cough testing, swallow function testing, and completion of questionnaires. Following the initial research evaluation, individuals will complete daily exercises of active or sham respiratory muscle strength training for several weeks with one telehealth or in-person session per week. The exercises will take 10-15 minutes to complete, and individuals will fill out training logs daily. Prior to transplantation and after completion of the breathing exercises, individuals will undergo a second research evaluation. Then, following surgery, individuals will undergo a third research evaluation and outcomes will be tracked via the electronic health records system.

Intervention / Behandling |
|---|---|
|
Experimentell: Active respiratory muscle strength training
Enrolled heart transplant patients will undergo active preoperative respiratory strength training using two respiratory strength training devices from enrollment until they receive a heart transplant. |
Devices will be set to 60% of participants' maximum expiratory pressure and maximum inspiratory pressure. Participants will complete training 7 days per week by performing 5 sets of 5 repetitions for both expiratory and inspiratory muscle strength training (a total of 50 repetitions). |
|
Sham Comparator: Sham respiratory muscle strength training
Enrolled heart transplant patients will undergo sham preoperative respiratory strength training using two respiratory strength training devices from enrollment until they receive a heart transplant. For individuals completing sham respiratory strength training, the spring will be removed from the devices as has been done in prior sham-controlled trials. |
Springs will be removed from devices to ensure training is done without resistance. Participants will complete training 7 days per week by performing 5 sets of 5 repetitions for both expiratory and inspiratory sham muscle strength training (a total of 50 repetitions). |

Patient-reported treatment burden
Tidsram: post-intervention/pre-surgery (an average of 2-6 weeks after baseline)
|
Patients will complete the exercise therapy burden questionnaire (ETBQ). Scores on the ETBQ range from 0-100 with higher scores indicating greater burden. |
post-intervention/pre-surgery (an average of 2-6 weeks after baseline)
|
|
Patient reported swallow function
Tidsram: pre-surgery (baseline), post-surgery
|
Patients will complete the swallowing and eating related fatigue (SERF) questionnaire. Scores on the SERF range from 0-48 with higher scores indicating greater impairment. |
pre-surgery (baseline), post-surgery
|
|
Change in penetration-aspiration scale scores between before and after surgery
Tidsram: pre-surgery (baseline), post-surgery
|
The penetration aspiration scale is a validated 8-point ordinal rating scale that measures the depth of airway invasion and the patient's response during swallowing. Scores range from 1 to 8 with a score of 1 indicating a safe swallow (best score) and 8 indicating silent aspiration (worst score). |
pre-surgery (baseline), post-surgery
|
|
Change in clinical frailty scale score
Tidsram: baseline, post-intervention/pre-surgery (an average of 2-6 weeks after baseline)
|
The Clinical Frailty Scale (CFS) is a measure of physical function. Scores on the CFS range from 1-9 with higher scores indicating greater impairment. |
baseline, post-intervention/pre-surgery (an average of 2-6 weeks after baseline)
