Abstract

Background Medically unexplained dyspnea (MUD) refers to a condition characterized by a sensation of dyspnea and is typically applied to patients presenting with anxiety and hyperventilation without cardiopulmonary explanations for their dyspnea. The diagnosis is difficult. We investigated whether descriptors of dyspnea and associated symptoms of MUD are differentially diagnostic. Methods A respiratory symptom checklist incorporating 61 spontaneously reported descriptors of dyspnea was administered to 96 patients with MUD and 195 patients with cardiopulmonary diseases. Symptom factors measuring different qualitative aspects of dyspnea were derived by a principal component analysis. The separation of two patient groups in terms of symptom factors was achieved by a discriminant analysis. Results Five factors grouped different attributes of dyspnea: urge to breathe, depth and frequency of breathing, difficulty breathing and phase of respiration, wheezing, and affective dyspnea. The other five factors grouped symptoms of anxiety, tingling, cough and sputum, palpitation, and out of control. A discriminant analysis allowed to separate two patient groups (R(2) = 0.45, p Conclusions Descriptors of dyspnea and associated symptoms allows satisfactory separation of patients with MUD from patients with cardiopulmonary diseases. A prospective study will be required to test the validity and predictive values of the descriptor model in another cohort of patients.

  • The affective component of dyspnoea has been regarded as a non-specific unpleasant or distressing experience and is thought to be more commonly experienced in medically unexplained shortness of breath, which may represent patients with BPD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
