  • Serious co-morbidities that may contribute to dyspnoea and/or reduce exercise capacity including:
  • oSevere cardiac disease (e.g., heart failure, coronary artery disease)
  • oSevere respiratory disease other than PAH (e.g., chronic obstructive pulmonary disease, interstitial lung disease)
  • oSevere obesity (Body mass index > 35 kg/m2)

  • oLong-term oxygen therapy
  • Current pregnancy
  • Current users of recreational drugs
