Pulmonary arterial hypertension (PAH)

Learn About PAH

PAH occurs when the very small arteries throughout the lungs narrow in diameter, which increases the resistance to blood flow through the lungs. In many cases the cause is unknown.

Symptoms and Diagnosis

Symptoms of PAH are similar to other lung diseases including asthma, COPD and can also mimic heart failure. Because of this, diagnosis requires numerous tests to determine the type and severity.

Treating and Managing

While there is no cure for PAH, treatment options exist. Here is what to expect after diagnosis, how to best manage the disease and where to find support.
