What is pulmonary hypertension?

Pulmonary hypertension is a disease that does not have a cure. The inside of the arteries in the lungs may be damaged, narrowed, or obstructed. Any of these changes can cause high blood pressure in the lungs.

As a result, the right side of the heart has to work harder to pump blood through narrowed arteries in the lungs. This can decrease blood flow throughout the body.

The extra stress causes the heart to enlarge and become less flexible. This affects the heart’s ability to pump blood out of the heart, through the lungs, and into the rest of the body.
