Revising the hemodynamic criteria for pulmonary hypertension: A perspective from China.

Abstract

At the 6th World Symposium on Pulmonary Hypertension (WSPH) in Nice, France, in 2018, the redefinition of the hemodynamic criteria for the diagnosis of pulmonary hypertension (PH) was proposed by a task force, suggesting a modification of the threshold value of the mean pulmonary arterial pressure (mPAP) for defining PH from ≥ 25 mmHg to > 20 mmHg. The proposed new hemodynamic criteria were published a year later in the proceedings of the 6th WSPH in European Respiratory Journal, which received considerable attention and sparked widespread controversy.[1]
