To evaluate the mechanisms and effects of bronchial thermoplasty on symptomatic improvement in subjects with severe bronchial asthma.
Safety,Efficacy
The mean change in Asthma Quality of Life Questionnaire score from baseline to after bronchial thermoplasty
The mean changes in the following parameters from baseline to after bronchial thermoplasty: 1) results of cardiopulmonary exercise testing, which include exercise time, peak Vo2, Borg scale, O2-pulse, VD/VT,VE/Vo2, VE/Vco2, delta FiO2, and ETCO2; 2) low frequency (LF) component, high frequency (HF) component, and LF/HF, which will be measured using heart rate variability during the day and at night alone; 3) Asthma Control Test score; 4) peak expiratory flow; 5) forced expiratory volume in one second (FEV1); 6) measurements of respiratory resistance and respiratory reactance, including R5, R20, R5-R20, and Fres; 7) results of the methacholine challenge test using the astograph methods, including Dmin and SGrs/Grs count; 8) the frequency of rescue drug (i.e., short-acting beta 2 agonist) use; and 9) frequency of clinical exacerbation of asthma, which requires steroid administration
