Abstract
In 2022, the European Society of Cardiology (ESC) and the European Respiratory Society (ERS) proposed new diagnostic criteria for pulmonary hypertension (PH). These criteria include significant changes to the definitions of pulmonary hemodynamic indices. Specifically, the threshold for mean pulmonary artery pressure (mPAP) has been lowered from ≥25 mmHg to >20 mmHg, and the threshold for pulmonary vascular resistance (PVR) has been adjusted from ≥3 Wood units (WU) to >2 WU. Additionally, the diagnostic criterion for exercise-induced PH has been reintroduced. To differentiate between non-severe and severe PH associated with lung disease, a differential threshold of 5 WU for PVR has been proposed. However, the threshold for mean pulmonary artery wedge pressure (PAWP) remains unchanged. While these new criteria could provide a more refined approach to clinical practice, they may also raise clinical concerns and questions regarding the diagnosis and management of PH.
