Updated hemodynamic definitions of pulmonary hypertension according to the 2022 ESC/ERS pulmonary hypertension guidelines.

Definition	Characteristics
Pulmonary hypertension	mPAP > 20 mmHg
Pre‐capillary PH	mPAP > 20 mmHg PVR > 2 WU PAWP ≤ 15 mmHg
Isolated post‐capillary PH	mPAP > 20 mmHg PVR < 2 WU PAWP > 15 mmHg
Combined pre‐ and post‐capillary PH	mPAP > 20 mmHg PVR > 2 WU PAWP > 15 mmHg
Exercise PH	mPAP/CO slope between rest and exercise > 3 mmHG/L/min

Abbreviations: CO, cardiac output; ESC, European Society of Cardiology; ERS, European Respiratory Society; mPAP, mean pulmonary artery pressure; PAWP, pulmonary artery wedge pressure; PH, pulmonary hypertension; PVR, pulmonary vascular resistance; WU, Wood units.
