Primary pulmonary hypertension (PPH) is high blood pressure in the lungs. It’s a rare lung disorder in which the blood vessels in the lungs narrow and the pressure in the pulmonary artery rises far above normal levels. The pulmonary arteries carry blood from your body to the lungs where carbon dioxide is traded for oxygen.
Pulmonary hypertension is a serious, chronic disease that can lead to heart failure if it’s not treated.
The cause of primary pulmonary hypertension (PPH) is unknown. Often, there is no underlying heart or lung disease causing the high blood pressure.
