Pulmonary Hypertension in Chronic Lung Disease and Hypoxia

It is important that defining PH should not be undertaken during an acute exacerbation, but under stable conditions.

RHC should be performed in patients with CLD when significant PH is suspected and the patient's management will likely be influenced by RHC results, including referral for transplantation, inclusion in clinical trials or registries, treatment of unmasked left heart dysfunction, or compassionate use of therapy.
