 AB    Primary pulmonary hypertension (PPH) is at present little understood. It
       is characterized by extensive remodeling of the pulmonary vasculature,
       with consequent deleterious hypertrophic changes in the right ventricle.
       Median survival is 2.6 years, although this varies with the severity of
       right heart failure. Although PPH can occur at any age and in either
       sex, it primarily affects young to middle-aged women. A genetic
       predisposition appears to be a component of this disease, triggered by
       presentation of a stimulus (e.g., drugs or HIV infection). Symptomatic
       presentation includes exertional dyspnea, chest pain, and syncope. At
       present, therapy consists principally of anticoagulation, calcium
       antagonists, nitric oxide inhalation, or continuous intravenous
       prostacyclin.
