Pulmonary hypertension (PH) is a general term for high blood pressure in the arteries connecting the lungs and heart. Pulmonary arterial hypertension (PAH) is a specific type of PH - think of it this way: all PAH is PH, but not all PH is PAH. PAH is a rare and progressive condition where tiny blood vessels in the lungs narrow, creating high blood pressure specifically in the lungs. This causes the right side of the heart to work harder than normal, which can lead to heart damage over time.

While PH affects about 1-3% of the global population, PAH is much rarer, affecting only about 15-30 cases per million people worldwide. Both conditions are more common in women than in men.
