About PAH

Pulmonary Arterial Hypertension (PAH) is a type of a broader condition known as pulmonary hypertension, which means high blood pressure in the lungs. PAH is characterized by scarring and narrowing of the small arteries in the lung, which increases pressure and the resistance to blood flow through the lungs.

The heart and lungs work together to collect and pump oxygen-rich blood throughout the body. Over time, the increased blood pressure in the lungs can damage the heart and reduce cardiac output, which can lead to a decrease in mobility and reduced quality of life.
