| Abstract: | Primary lung hypertension (PLH) is a rare disease of unknown etiology seen largely in young persons. PLH shows rapid progression with lethal outcome 3-5 years after registration of the first symptoms. Early diagnosis of the disease is difficult. A case described in the article illustrates real difficulties in PLH diagnosis and treatment. The patient several times lost consciousness for a short time at insignificant exercise. This phenomenon has not been described in the literature so far. |
