Official title
The Effect of Inspiratory Muscle Training on Dysfunctional Breathing and Functional Ability in Patients With Chronic Heart Failure. A Study Protocol for a Randomized Controlled Trial
Overview
The effect of inspiratory muscle training on breathing pattern and functionality in patients with chronic heart failure.
Detailed description
The study protocol aims to examine the impact of inspiratory muscle training on dysfunctional breathing and functional ability in patients with chronic heart failure. Inspiratory muscle training is a low-cost intervention that might improve the breathing pattern, functionality and overall quality of life in patients with chronic heart failure
Interventions
- Device Inspiratory muscle training
Participants will perform 20 sessions of respiratory muscle strengthening (20 minutes at 30-60% of MIP), using the Threshold Inspiratory Muscle Training device
Primary outcome measures
- Diaphragmatic Thickness [Time frame: From enrollment to the end of treatment at 4 weeks]
- Dysfunctional breathing [Time frame: From enrollment to the end of treatment at 4 weeks]
- Functional ability [Time frame: From enrollment to the end of treatment at 4 weeks]
Secondary outcome measures (3)
- Maximal inspiratory pressure [Time frame: From enrollment to the end of treatment at 4 weeks]
- Functional Dyspnea [Time frame: From enrollment to the end of treatment at 4 weeks]
- Health Related Quality of life [Time frame: From enrollment to the end of treatment at 4 weeks]
Eligibility criteria
Inclusion criteria
- adults aged ≥ 18 years
- diagnosis of heart failure within the previous three to twelve months
- current outpatients in a stable optimal medical regimen for at least 3 months
- able to perform inspiratory muscle training
- clinically stable, without hospital admission in the previous 3 months and without participation in any other training program in the previous 6 months
Exclusion criteria
- unstable angina
- recent acute myocardial infarction
- uncontrolled hypertension
- valve disease

- history of exercise-induced asthma
- smokers
