Determination of PH according to current ESC Guidelines (2015) and according to the Sixth World Symposium on Pulmonary Hypertension (2018). Mean pulmonary arterial pressure, (mPAP); Diastolic pressure gradient (DPG); Pulmonary vascular resistance (PVR); Pulmonary capillary wedge pressure (PCWP).

Determination Of PH According to Current ESC Guidelines (2015)
PH Subtypes	Hemodynamics
pre-capillary PH	mPAP ≥ 25 mmHg PCWP ≤ 15 mmHg
isolated post-capillary PH	mPAP ≥ 25 mmHg PCWP > 15 mmHg PVR ≤ 3 WU DPG < 7 mmHg
combined pre- and post-capillary PH	mPAP ≥ 25 mmHg PCWP > 15 mmHg PVR > 3 WU DPG ≥ 7 mmHg
Determination Of PH According To 6th World Symposium On Pulmonary Hypertension (2018)
PH Subtypes	Hemodynamics
pre-capillary PH	mPAP > 20 mmHg PCWP ≤ 15 mmHg PVR ≥ 3 WU
isolated post-capillary PH	mPAP > 20 mmHg PCWP > 15 mmHg PVR < 3 WU
combined pre- and post-capillary PH	mPAP > 20 mmHg PCWP > 15 mmHg PVR ≥ 3 WU
