La dyspnée dans la sarcoïdose

Dyspnea is a common complaint in sarcoidosis. Its objective component is exercise limitation and is of multifactorial origin. It may be related to ventilatory, cardiovascular or gas exchange impairments. The gold standard for analyzing this objective component of dyspnea is cardiopulmonary exercise testing. Its yield is independent of observed radiological or resting lung function disturbances. The subjective component of dyspnea is dual, one sensory and the other affective. Distinguishing between these two components through specific questionnaires such as Dyspnea 12 may provide a better overall quality of care.
