A Study to Assess the Effectiveness of the Inspiratory Muscle Training Program on level of Dyspnea among Heart Failure Patients Attending Cardiac Tertiary Care Centers, Maharashtra

Abstract

Background of the study: Dyspnea is defined as an uncomfortable sensation in breathing, it is a cardinal symptom for cardiorespiratory diseases. As heart failure progresses, dyspnea becomes increasingly troublesome for these patients and frequently worsens their quality of life.Dyspnea is more closed associated with cardiac mortality rate than angina.1Inspiratory muscle weakness can occur in 30% to 50% of the heart failure patients, which is associated with the reduction in functional capacity and reduction in the quality of life and poor prognosis of these individuals. Inspiratory Muscle training is an effective therapeutic approach to reduce the dyspnea and muscle fatigue of heart failure patients, promoting their sense of independence and psychosocial health.2 Problem Statement: A study to assess the effectiveness of the inspiratory muscle training program on level of dyspnea among heart failure patients attending cardiac tertiary care centers, Maharashtra. Objectives: The outcome of this study was to assess the level of dyspnea and to assess the effectiveness of inspiratory muscle training on level of dyspnea among heart failure patients.Result: The study results showed that, before the level of dyspnea in experimental group was 36.94% with mean and standard deviation of 4.33±1.25, whereas the level of dyspnea in control group was 36.06% followed by 4.4 mean and ±1.25 standard deviation. Then the effectiveness of inspiratory muscle training was found using paired t-test, the calculated t value was 15.05 with the degree of freedom 29 which shows the significant difference in the pretest and posttest level of dyspnea. Conclusion: This study concluded that, the inspiratory muscle training program as an alternative approach, which was effective in reduction of level of dyspnea among heart failure patients
