Effect of Endobronchial Valve Treatment on Skeletal Muscles, Fatigue, and Sleep in Severe Emphysema Patients

Our results show that quadriceps muscle size and function, as well as fatigue, significantly improve following EBV treatment in severe emphysema patients. However, BLVR seems to have no impact on intercostal thickening fraction and patient-reported sleep quality. This study highlights the beneficial extrapulmonary effects of EBV treatment in patients with severe emphysema, further supporting its clinical use.
