Clinical studies in pulmonary hypertension (PH) have historically focused primarily on Group 1 disease and, more specifically, on idiopathic PAH. However, there are many subtypes of PH within Group 1 and other pulmonary hypertension classes of which the physician must be aware. Awareness can lead to screening, earlier detection, and expedient referral from the community level to the PH specialty center. This program looks at forms of PH not routinely discussed, including PAH associated with systemic sclerosis and connective tissue disease, PAH associated with congenital heart disease, PH associated with interstitial lung disease, and finally, drug- and toxin-induced PH. The program focuses on screening, referral diagnosis, and management of the disease.
