Haemodynamics in pulmonary hypertension associated with hereditary haemorrhagic telangiectasia.

Haemodynamics	PAH	High Output PH
Mpap (mmHg)	++	+
PAWP (mmHg)	= (≤ 15)	=/+
PVR (Wood units)	++ (> 3)	=
CO (L/min)	−	++
DPG (mmHg)		− (< 7)

PH, pulmonary hypertension; HPAH, heritable pulmonary arterial hypertension; mPAP, mean pulmonary artery pressure; PAWP, pulmonary artery wedge pressure; PVR, pulmonary vascular resistance; CO, cardiac output; DPG, diastolic pressure gradient (diastolic PAP—mean PAWP). +, increased; =, normal; −, decreased; ++, severely increased.
