RÉSUMÉ
Pulmonary hypertension(PH)has been defined as mean pulmonary arterial pressure(mPAP)≥25 mmHg at rest,measured by right heart catheterisation. The 6 th WSPH suggested a new pressure level to define an abnormal elevation as the mPAP>20 mmHg and the need for PVR≥3 WU to define the presence of pre-capillary PH. Regarding clinical classification,the main changes were the inclusion in group 1 of a subgroup“pulmonary arterial hypertension(PAH)long-term responders to calcium channel blockers”and a subgroup“PAH with overt features of venous/capillaries involvement“.
