Diagnosis and Management
of Pulmonary Hypertension

Over the last few decades, the study of pulmonary arterial hypertension (PAH) has
become one of the most rapidly developing fi elds of cardiopulmonary medicine.
This may seem surprising considering the relatively small number of patients who
carry this diagnosis, but like many rare diseases that were once untreatable, interest
in PAH has been spurred on by an intense desire to improve the outcome of those
who are affected. At the same time, numerous discoveries in the fi eld of pulmonary
vascular biology have led to a marked shift in how we view the pulmonary circulation. Many of these discoveries have led directly to the development and licensing
of over a dozen drugs in the last 20 years.
