title: [Evaluation of exercise performance and quality of life after lung volume reduction surgery for severe emphysema].
abstract: OBJECTIVE
  To evaluate grade of dyspnea, exercise performance and quality of life pre and post-lung volume reduction surgery in patients with severe emphysema.
  
  
  METHODS
  Serial measurement of lung function, cardiopulmonary exercise test and 6-minute walk distance, and the dyspnea grade assessment by modified dyspnea scale of English Medical Research Council and quality of life by Notting-ham Health Profile were all done before and at 3, 6, 12 months after surgery.
  
  
  RESULTS
  FVC, FEV1, MVV increased (P < 0.01) and RV, TLC, RV/TLC decreased at 3, 6, 12 months after surgery (P < 0.01), WATT, TET, VO2max, VO2max/HR, VEmax, VTmax, 6MWD were all improved (P < 0.01), and the dyspnea grade was declined as well as the NHP score(P < 0.01 or < 0.05).
  
  
  CONCLUSIONS
  Lung volume reduction surgery in patients with severe emphysema may improve patient's exercise performance and quality of life.
