Table 2. Hemodynamic definitions of PH.

PH type	Hemodynamic definitions
PH-LHD	mPAP ≥20 mmHg; PCWP >15 mmHg
IpcPH	PVR ≤3WU; DPG <7 mmHg; CPA ≥2.3 mL/mmHg
CpcPH	PVR >3WU; DPG ≥7 mmHg; CPA <2.3 mL/mmHg

Modified from (138). PH-LHD, pulmonary hypertension associated with left heart disease; mPAP, mean pulmonary artery pressure; PCWP, pulmonary capillary wedge pressure; IpcPH, isolated post-capillary pulmonary hypertension; CpcPH, combined post- and precapillary pulmonary hypertension; PVR, pulmonary vascular resistance; WU, Wood units; DPG, diastolic pressure gradient; CPA, pulmonary artery compliance.
