In patients with heart failure, diaphragm dysfunction contributes to decreased quality of life while simultaneously increasing morbidity and mortality. Inspiratory muscle weakness is observed in 30-50% of patients, with the severity of weakness increasing as the disease progresses. Patients exhibit reduced exercise capacity, peripheral and respiratory muscle strength, decreased respiratory function, increased dyspnea, fatigue, and worsened quality of life. However, it is unclear how these parameters will change in patients with inspiratory muscle weakness. Therefore, the study aimed to compare functional exercise capacity, pulmonary function, peripheral muscle strength, dyspnea, fatigue, quality of life and physical activity level in heart failure patients with and without inspiratory muscle weakness and healthy controls
