Summary

This study tested a procedure called bronchial thermoplasty for people with severe asthma that is not controlled by standard treatments. The treatment uses heat to thin the airway muscles, aiming to reduce breathlessness during exercise. 14 participants were enrolled, and the main goal was to see if the treatment improved lung function during physical activity.
