Haemodynamic profiles in patients with hereditary haemorrhagic telangiectasia and pulmonary hypertension(PH)
| Profile | P̄pa | CO | PAOP | TPG | PVR |
| PH, high flow, LV failure | ↑ | ↑↑ | High-normal or ↑ | Normal | Normal |
| PAH | ↑↑ | ↓ | Normal | ↑ | ↑↑ |
P̄pa: mean pulmonary arterial pressure; CO: cardiac output; PAOP: pulmonary artery occlusion pressure; TPG: transpulmonary gradient; PVR: pulmonary vascular resistance; LV: left ventricular; PAH: pulmonary arterial hypertension; ↑: increase; ↑↑: large increase; ↓: decrease.
