Abstract

Rationale: Panic attacks are common in chronic obstructive pulmonary disease (COPD), and the prevalence of panic disorder is at least 10 times higher than in the general population. In the current study, we examined resistive load perception in patients with COPD with and without panic attacks. Objectives: We tested competing hypotheses, based on conflicting results of earlier studies, that those patients with COPD with panic attacks or panic disorder would show either heightened or blunted perception of dyspnea as the magnitude of inspiratory resistive loads increased. Methods: We compared 20 patients with COPD with panic attacks or panic disorder, 20 patients without panic, and 20 healthy, age-matched subjects using an inspiratory resistive load–testing protocol. Measurements and Main Results: We administered a diagnostic interview for panic attacks and panic disorder. We measured perceived dyspnea in response to increasing inspiratory resistive loads (modified Borg scale) and several respiratory variables. Dyspnea ratings increased linearly for all groups as the size of resistive loads increased. No significant differences were found between groups on the respiratory variables. Patients with COPD with panic attacks or panic disorder rated their level of dyspnea significantly higher than did other subjects. Conclusions: Patients with COPD with panic attacks showed heightened sensitivity to inspiratory loads. The result reinforces the influence of psychological factors on symptom perception in this disease.

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.
