WHAT IS PULMONARY ARTERIAL HYPERTENSION (PAH)?
Pulmonary hypertension is when blood pressure is elevated in the lungs.
Pulmonary arterial hypertension (PAH) is one form of pulmonary hypertension. It is caused by narrowing of the blood vessels in the lungs.
People can have just PAH (not with any other disease). It also can occur with other diseases.
It may be hard to diagnose. Many of the same symptoms occur in much more common lung diseases.
It is a complex disease. It will usually worsen without treatment.

- Chest pain
- Heart palpitations
- Fatigue (feeling tired)
- Swelling of feet, legs, belly
- Fainting or dizziness
- Oral medications (that you swallow)
- Inhaled medications (that you breathe in)
- Intravenous medications (that are inserted directly into your veins through a needle)
- Infused medications (that are pumped in just under the skin)

- Connective tissue disease (eg, scleroderma, lupus, or rheumatoid arthritis)
- Cirrhosis of the liver

- Treatment depends on:

- Test results
- At-home support
- More than one treatment at a time is more effective
