Newly revealed biological mechanisms that underlie the development of pulmonary arterial hypertension (PAH) support activating BMPR2, the protein mutated in most familial PAH cases, as a treatment strategy, according to a study that investigated human cells and mouse models. A recent case series showed potential for the BMPR2-activator…

Supplemental long-term oxygen therapy is the only effective treatment for people with pulmonary hypertension (PH) associated with chronic obstructive pulmonary disease (COPD) who have low blood oxygen, according to a systematic review of studies.

The short-term survival rate of patients with both human immunodeficiency virus (HIV) and pulmonary arterial hypertension (PAH) — dubbed HIV-PAH — is similar to that of people with idiopathic or familial forms of PAH, according to the results of a Spanish study spanning 20 years. Patients with HIV-PAH also…

Patient registries are a hot topic of rare disease research and many organizations are taking advantage of this resource by signing up their patient communities and connecting with researchers. Eric Sid, MD, program officer for the Office of Rare Diseases Research (ORDR), said it is difficult to estimate how…

Maternal and fetal complications are frequent across pulmonary hypertension (PH) groups, with about a third of patients experiencing an uneventful pregnancy, a small single-center study shows. While PH due to left heart disease is often thought to carry a lower risk of pregnancy complications than pulmonary arterial…
