Symptoms, impacts, and suitability of the Pulmonary Arterial Hypertension - Symptoms and Impact (PAH-SYMPACT™) questionnaire in patients with chronic thromboembolic pulmonary hypertension (CTEPH): a qualitative interview study.BACKGROUND
 This qualitative study aimed to better understand the symptoms of CTEPH and how they affect patients' lives, as well as to determine the appropriateness of the Pulmonary Arterial Hypertension - Symptoms and Impact (PAH-SYMPACT™) questionnaire for use in this patient population.


 They also provided feedback on the comprehensibility and relevance of the PAH-SYMPACT™'s instructions, items, and response options.


 The PAH-SYMPACT™ items were relevant to most participants and reflected their experience of CTEPH.  All participants indicated that no important CTEPH symptoms were missing from the PAH-SYMPACT™.  Overall, the instructions, items, and response options of the PAH-SYMPACT™ were clear and easy to understand.


 The symptoms and impacts experienced by patients with CTEPH align with items included in the PAH-SYMPACT™.  The PAH-SYMPACT™ appears to be fit for purpose for assessing disease status in patients with CTEPH.
