PH-Targeted Therapies Show Modest-at-Best Benefit in PH Due to Left Heart Disease, Review Study Reports

A large review of clinical trials evaluating whether pulmonary hypertension (PH)-targeted therapies can improve exercise capacity in patients with pulmonary hypertension due to left heart disease (PH-LHD) found varying effectiveness and modest benefit. The findings were reported in the study “Pulmonary hypertension-targeted therapies in heart failure: A systematic…

Testing for EIF2AK4 Mutations May Help Distinguish Between PAH and Other Severe PH Diseases, Study Says

Patients with mutations in the EIF2AK4 gene have worse outcomes than others with pulmonary arterial hypertension (PAH), researchers report, suggesting that genetic tests be given these people — often diagnosed with PAH — to determine if they actually have pulmonary vena-occlusive disease (PVOD) or pulmonary capillary hemangiomatosis (PCH) and can be treated…

Case Studies Highlight Diversity of Rheumatoid Arthritis-Associated PH

A recent article that presented case studies of three patients with rheumatoid arthritis-associated pulmonary hypertension (PH), highlights the diversity of the underlying causes of the disease, and emphasizes the importance of diagnosing it early. The study “Rheumatoid arthritis associated pulmonary hypertension: Clinical challenges reflecting the diversity of pathophysiology”…

Interferon Therapy Seen as Notable Risk Factor for Pulmonary Arterial Hypertension

Pulmonary arterial hypertension (PAH) is a rare complication in hepatitis C or multiple sclerosis patients using interferon α or β therapy, but still one that’s substantially more common in these people than in the general population, suggesting a link between the therapy and PAH, researchers reported. Type I interferons, including interferon α and β, are naturally occurring compounds in the body,…
