Pulmonary arterial hypertension (PAH)
- Group 1 – Elevation of pressure in the pulmonary arteries (idiopathic, hereditary, toxin induced). Examples include idiopathic PAH, hereditary PAH, and PAH due to connective tissue disease, HIV infection, portal hypertension, congenital heart disease, schistosomiasis, or drug use.
- Group 2 – Elevation of pressure in the pulmonary venous system due to left heart disease.
- Group 3 – Elevation of pressure in the pulmonary venous system due to lung disease or hypoxia.
- Group 4 – Chronic thromboembolic pulmonary hypertension.
- Group 5 – Pulmonary hypertension with unclear or multifactorial mechanisms.
Multiple pulmonary metastases can be a cause of rapid-onset pulmonary hypertension.
