Gene Activity Analysis of Whole Blood Finds 3 Major PAH Subgroups

Gene activity analysis of whole blood collected from people with pulmonary arterial hypertension (PAH) identified three patient subgroups associated with distinct clinical features and outcomes, a study concluded. These findings may provide molecular insights into the development of PAH, improve disease risk assessments, and potentially guide individual treatment strategies,…

CTEPH Study Ties Lung Arterial Obstruction to Airflow Obstruction

Increased lung arterial obstruction is significantly associated with greater airflow obstruction in people with chronic thromboembolic pulmonary hypertension (CTEPH) and without a smoking history, a study shows. Notably, airflow obstruction, reflected by a reduced ability to exhale quickly, was lessened with reduced arterial obstruction and improved blood flow following…

Pulmonary Hypertension Tied to Increased Cancer Risk

People with pulmonary hypertension are at increased risk of developing cancer, especially lung and skin cancers, a new study indicates. The study, “Pulmonary hypertension is associated with an increased incidence of cancer diagnoses,” was published in the journal Pulmonary Circulation. Pulmonary hypertension (PH) refers to…
