What is the prognosis for pulmonary hypertension?

Generally, the prognosis of pulmonary varies depending on the underlying condition that is causing it. For primary pulmonary hypertension, the overall prognosis depends on the severity and whether treatment was instituted. The statistics show a survival of about 3 years in primary pulmonary hypertension without any therapy. Some of the other factors may indicate even poorer prognosis which include severe symptoms, age of onset greater than 45 years, evidence of right sided heart failure, and failure to respond to treatment. For patients with primary pulmonary hypertension who get started on treatment and respond to it, the prognosis is better. Studies are underway to determine optimal treatment regimens.
