Is pulmonary rehabilitation successful for COPD irrespective of MRC dyspnoea grade?
Patients with COPD, of all MRC dyspnoea grades, benefit comparably from pulmonary rehabilitation achieving both statistically and clinically meaningful improvements in exercise performance. MRC grade should therefore not be used to exclude patients from pulmonary rehabilitation.
Grade-stage category at diagnosis predicts overall and BC mortality but not mortality from other causes. Thus, particularly for INV disease, because BC represents the major threat to life, aggressive therapies that have been shown to be effective are justified.
