Introduction |
Patients with advanced emphysema eligible for bronchoscopic lung volume reduction (BLVR) using endobronchial valves (EBV) are characterized by severe static lung hyperinflation, which can be considered a treatable trait. Other treatable traits (TTs), which are assumed to be present in this highly selected patient group, have not been studied in detail nor how they may affect health-related quality of life (HRQL).
Aims |
We aimed to evaluate a spectrum of TTs in COPD patients eligible for EBV treatment and their association with HRQL.
Methods |
The SoLVE study (NCT03474471) was a prospective multicenter randomized controlled trial to examine the impact of pulmonary rehabilitation in COPD patients receiving EBV. The presence/absence of 16 TTs was based on pre-defined thresholds. HRQL was assessed with the St. George's Respiratory Questionnaire (SGRQ). Subjects were stratified into two groups, using the median split method, into higher or lower SGRQ total score. Logistic regression assessed the odds ratio (OR) of having a higher SGRQ total score per TT.
Results |
Ninety-seven subjects were included, the mean number of TTs per patient was 8.1 ± 2.5. Low physical activity (95%), poor exercise capacity (94%) and severe fatigue (75%) were the most prevalent TTs. The sum of TTs present in a subject was associated with the SGRQ total score (r = 0.53; p < 0.001). Severe fatigue, depression, and anxiety were predictors of having a higher SGRQ total score.
Conclusions |
A high prevalence and co-occurrence of multiple TTs were identified in emphysema patients eligible for EBV. Patients with a higher number of TTs were more likely to have worse HRQL.

• | A heterogenous spectrum of TTs exist in BLVR-EBV candidates. |
• | The most prevalent TTs were low physical activity, poor exercise capacity and severe fatigue. |
• | Severe fatigue, anxiety and depression increased the likelihood of a worse quality of life. |
