Why the study?
It was unknown whether multidimensional measurement of breathlessness is useful to differentiate individuals with abnormal versus normal exertional breathlessness intensity.
Does the multidimensional dyspnea profile differentiate between outpatients with abnormal versus normal exertional breathlessness intensity during an incremental exercise test?
Population
92 outpatients aged ≥ 18 years performing a symptom-limited cycle incremental exercise test
Comparison
Abnormally high breathlessness vs breathlessness within normal ranges
Design
Secondary analysis of a randomized controlled trial

Peak-exercise MDP ratings do not differentiate exertional breathlessness severity in outpatients; leaves open its clinical utility and requires prospective validation.
Does the multidimensional dyspnea profile differentiate between outpatients with abnormal versus normal exertional breathlessness intensity during an incremental exercise test?
Multidimensional breathlessness dimensions measured at peak exercise do not differentiate between patients with normal versus abnormally high exertional breathlessness.
