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.
Some forms of pulmonary hypertension are linked to a gene defect that can run in families. Researchers believe this gene mutation makes the blood vessels more sensitive to certain factors and they constrict, or narrow, when exposed to these factors.
The following are the most common symptoms for primary pulmonary hypertension (PPH). Symptoms can develop so slowly that you can have it for years without knowing it. However, each person may experience symptoms differently. Symptoms may include:
