What is PPH? Primary pulmonary hypertension, or PPH, is an increase in blood pressure in the pulmonary artery, pulmonary vein, or pulmonary arteries.  Dr. Ernst von Romberg first identified PPH in 1891.  Primary pulmonary hypertension is a rare, progressive disorder characterized by high blood pressure (hypertension) of the main artery of the lungs, called the pulmonary artery.  The pulmonary artery is the blood vessel that carries blood from the heart through the lungs. There are five different types of PPH: Arterial PPH; Venous PPH; Hypoxic PPH; Thromboembolic PPH; and Miscellaneous PPH. Symptoms of primary pulmonary hypertension include shortness of breath (especially during exercise), chest pain, and fainting episodes. The exact cause of primary pulmonary hypertension is unknown. Primary pulmonary hypertension is difficult to diagnose – often mistaken for more common heart and lung problems.  If left untreated, PPH can be deadly.  For more information on living with PPH see our PPH Treatment.
