Pulmonary Arterial Hypertension (PAH)
Pulmonary arterial hypertension (PAH) is continuous high blood pressure in the pulmonary artery.
The average blood pressure in a normal pulmonary artery is about 14 mmHg when the person is
resting. In PAH, the average is usually greater than 25 mmHg. PAH is a serious condition for
which there are beneficial treatments, but no cure.
There are two types of PAH:
- Primary pulmonary arterial hypertension (PPAH)- inherited or occurs for no known reason.
- Secondary pulmonary arterial hypertension (SPAH)- caused by or occurs because of another
condition. The conditions include chronic heart or lung disease, blood clots in the lungs, or a
disease like
scleroderma.
