According to the revised haemodynamic definition, PAH may be diagnosed in patients with mPAP >20 mmHg and PVR >2 WU. Yet, the efficacy of drugs approved for PAH has only been demonstrated in patients with mPAP ≥25 mmHg and PVR >3 WU (see , ). No data are available for the efficacy of drugs approved for PAH in patients whose mPAP is <25 mmHg and whose PVR is <3 WU. Hence, for such patients, the efficacy of drugs approved for PAH has not been established.
