简要总结
Heart failure is a complex clinical syndrome manifesting as inability to supply adequate blood flow throughout the body due to any structural or functional cardiac abnormality. The most common complaints are exercise intolerance, balance, dyspnea, and fatigue in patients with heart failure. It is clearly stated that pulmonary muscle weakness is prevalent and contributes to exercise intolerance in patients with heart failure. Purpose of the study was to evaluate the efficacy of inspiratory muscle traning on pulmonary muscle strength, pulmonary function test, functional capacity and quality of life. The tools used were 6-minute walk test, spirometry, IMT threshold device for IMT strength, and Quality of life. Study was conducted in 20 patients in single group and pre and post values were evaluated. The significance this study bears was that it helped defining for us that to how much extent we can improve the physical and pulmonary functional capacity using inspiratory muscle training. Data were analysed using spss 22.0.mean and standard deviation were calculated. Appropirate the stasitical test were used after checking normailty of data. Parametric test were used for data analysis using SPSS 22

结局指标
主要结局
Pulmonary function test.
时间窗: 6 week
Measurements of forced vital capacity and forced expiratory volume in 1, forced expiratory volume in one second/forced vital capacity, peak expiratory pressure was obtained with a computerized spiro-lab device as recommended by the European respiratory society, and results were expressed as a percentage of predicted values.
Six-minute walk test (6MWT) Distance
时间窗: 6 week
Six-minute walk test (6MWT) was applied in a 30-m unobstructed corridor. Patients and controls were instructed to walk at their own pace but to cover as much meter as possible within 6 min. Each minute standardized encouragement was given to the patients. Patients were allowed to stop and rest during the test but were instructed to go on walking as soon as they were able to do so. Heart rate and spo2 were monitored using pulse oximetry before and ending the test. Maximum heart rate values achieved during the tests were recorded. The rate of the perceived exertional scale was used before and after the 6MWT. The 6MWT distance is expressed as a percentage of the predicted values.
SF-36
时间窗: 6 week
Quality of life was assessed using SF-36. The SF-36 is a generic measure, consisting of eight subscales and 36 items. These subscales are physical functioning, role-physical, role- emotional, mental health, social functioning, bodily pain, general health. All subscales range from 0 (worst possible) to100 points (best health).
