Patients’ economic healthcare status influences the opinion of pulmonary arterial hypertension (PAH) experts on pulmonary vasoreactivity testing in pulmonary hypertension due to lung disease. An international cohort of pulmonary vascular disease experts (N = 105) completed an Internet-based survey soliciting a response of (dis)agreement to the following statement: “It is reasonable to perform pulmonary vasoreactivity testing as part of the clinical evaluation for patients with suspected chronic lung disease–induced pulmonary hypertension (i.e., World Health Organization [WHO] group 3 pulmonary hypertension).” Results are presented by primary health insurance coverage (national healthcare system vs. private healthcare insurance) of PAH patients in the practice of each respondent, as reported in the survey by respondents. Data are expressed as mean ± SD.
