About
The study aims to compare the effects of inspiratory muscle training and Baduanjin exercises on pulmonary function, exercise capacity, and quality of life in patients with hypertrophic cardiomyopathy. By investigating these interventions, the investigators seek to introduce novel approaches that can enhance pulmonary function, exercise capacity, and overall quality of life for these patients.
In the study, which will involve three groups-the control group, the inspiratory muscle training (IMT) group, and the Baduanjin group-it was calculated that a total of 51 patients, with 17 in each group (n = 17), should be included.
The IMT group will use an inspiratory muscle training device twice a day, every day of the week, for 15 minutes. This training will continue for 8 weeks, with supervision once a week and unsupervised sessions on the other days.
The Baduanjin group will participate in a 50-minute exercise program, which includes a 10-minute warm-up, a 30-minute routine of eight separate movements, and a 10-minute cool-down. This will occur three times a week (twice in person and once online) for 8 weeks.
Full description
Hypertrophic cardiomyopathy (HCM) is characterized by a left ventricular wall thickness exceeding 15 millimeters (mm), as assessed by echocardiography and cardiac magnetic resonance imaging (MRI). It is a common genetic heart disease worldwide, known to cause left ventricular outflow tract obstruction, mitral regurgitation, diastolic dysfunction, myocardial ischemia, arrhythmias, and autonomic dysfunction (PubMed identification number (ID): 29655825, 28912181, 24998133, 30110588, 33229115).
Many patients with HCM are asymptomatic, and the condition is often identified incidentally during routine screening. Symptomatic patients may experience dyspnea on exertion, chest pain, syncope, or presyncope (PubMed ID:11886323). Even when left ventricular systolic function is preserved, patients frequently develop symptoms such as dyspnea and fatigue, leading to exercise intolerance in the majority (PubMed ID:10913477).
HCM is a heterogeneous disease with a varied clinical course. In addition to these symptoms, patients may also face decreased exercise capacity and reduced quality of life (PubMed ID:19253387, 9326995). Furthermore, despite the well-established cardiovascular and overall health benefits of regular physical activity, many patients with HCM exhibit a high prevalence of physical inactivity (PubMed ID: 23340032, 27547438).
Studies on inspiratory muscle training have demonstrated its benefits in improving respiratory function, respiratory muscle strength, quality of life, and exercise capacity across various patient groups including chronic obstructive pulmonary disease, cystic fibrosis, spinal cord injury, and heart failure. It also helps alleviate symptoms of dyspnea and fatigue (PubMed ID:32209709, 30827470, 32936904, 31429207, 31937553). Additionally, inspiratory muscle training has been shown to enhance physical activity levels in different patient cohorts (PubMed ID: 17534784).
Research indicates that Baduanjin exercises can serve as a complementary and alternative treatment for cardiovascular patients, improving clinical outcomes and reducing adverse cardiovascular events (PubMed ID:30059552). Furthermore, studies have highlighted their positive effects on quality of life and exercise capacity in diverse populations such as healthy individuals and those with conditions like heart failure, Parkinson's disease, osteoarthritis, and chronic fatigue syndrome, while also mitigating fatigue symptoms (PubMed ID: 36436262, 19051349, 27627031, 23001463, 18315512, 26083663, 25610473, 27938498).
Based on existing literature, the investigators believe that inspiratory muscle training and Baduanjin exercises could potentially benefit patients with HCM by alleviating associated symptoms. However, there is a notable scarcity of studies investigating different exercise modalities in HCM patients. To the investigators' knowledge, no studies have specifically examined the effects of inspiratory muscle training or Baduanjin exercises in this population.
The study aims to fill this gap by being the first to compare the impacts of inspiratory muscle training and Baduanjin exercises on pulmonary function, exercise capacity, and quality of life in patients with HCM. Through this research, the investigators seek to introduce new approaches that enhance pulmonary function, exercise capacity, and overall quality of life for these patients.
