Breathlessness despite optimal pathophysiological treatment: on the relevance of being chronic

With regard to the letter from Morélot-Panzini and colleagues in response to our Perspective [1], it is good to see support for the concept of a clinical syndrome and its potential in raising awareness of the needs of such patients in the minds of all clinicians; we welcome the ongoing discussion. It serves to highlight the importance of this neglected patient group and clinical topic, as well as the process for how an internationally agreed name and definition in English can be translated both linguistically and culturally in non-English-speaking countries. This letter highlights the thought processes that will need to occur in each translation of the concept. In seeing this work already occurring, our Perspective [1] has already achieved one of its aims.
