Effect of Inspiratory Muscle Training on Quality of Life in Patients with Chronic Heart Failure

Abstract
Background: The present study was applied on thirty patients with chronic heart failure to detect the efficacy of inspiratory muscle training on their quality of life.
Aim of Study: The present study was conducted to inves-tigate the efficacy of inspiratory muscle training on quality of life in patients with chronic heart failure.
Material and Methods: Thirty chronic heart failure patients were included in this study, their ages ranged from 50 to 60 years, they had Body mass index (BMI) ranged from 25-29.9 (kg/m2), they were selected from Tajora Heart Hospital in Libya and at the out-patient clinic, Faculty of Physical Therapy, Cairo University. They were divided randomly into two equal groups (A and B). Group (A) received selected physical therapy program about half an hour, while Group (B) received same physical therapy program that applied in the group (A) in addition to inspiratory muscle training using Inspiratory Muscle Trainer (IMT). The variables that used on this study, included Quality of Life Questionnaire (QLQ), dyspnea scale and ejection fraction, were assessed before and after treatment program in both groups. Both groups received treatment program 3 times/week for twelve weeks.
Results: The results revealed significant improvement of all measured variables in two groups after twelve successive weeks, also revealed significant difference when compared the two groups after treatment in favor of the group B.
Conclusion: Within the limitation of the present study it could be concluded that: The IMT results in marked improve-ment in Quality of Life Questionnaire (QLQ), dyspnea scale and ejection fraction.
