Treatment with cannabidiol (CBD) reduced inflammation and lessened damaging oxidative stress in a rat model of pulmonary hypertension (PH), a new study reports. “The promising results of our research may form the basis for a more detailed study of the effects of CBD or its derivatives on PH, especially…

The U.S. Food and Drug Administration (FDA) has approved Tyvaso DPI, a dry powder, inhaled formulation of treprostinil, to improve exercise ability in people with pulmonary arterial hypertension (PAH) or pulmonary hypertension associated with interstitial lung disease (PH-ILD). Tyvaso DPI is now the only dry powder inhaler approved…

Even with modern advances in treatments, many people in the U.S. with pulmonary arterial hypertension (PAH) are at an “unacceptably high” risk of mortality, a new study shows. The study, “Mortality in Pulmonary Arterial Hypertension in the Modern Era: Early Insights From the Pulmonary Hypertension Association Registry,” was…

The European Commission is expected to propose a new governing framework for health data next month, called the European Health Data Space (EHDS), with the aim of connecting national health systems to facilitate secure and efficient transfer of data across systems in different European nations. The move is expected to…

Combining measures of symptom severity, physical function, and heart health can help predict survival outcomes in pulmonary arterial hypertension (PAH), according to a new study. The study, “Prognostic value of improvement endpoints in pulmonary arterial hypertension trials: A COMPERA analysis,” was published in The Journal of Heart and…

People with pulmonary arterial hypertension of unknown cause, or idiopathic disease, who are older, male, or of low socioeconomic status are at higher risk of death, according to a study from Korea. Researchers also found an overall survival rate of more than 50% among newly diagnosed patients. The study,…

A new company spin-out from the University of Bath, in the U.K., is developing machine learning technologies that aim to improve the accuracy of a pulmonary hypertension (PH) diagnosis by analyzing routinely acquired images of the lungs. “Using our machine learning based software we can bring the expertise of…

Pulmonary hypertension (PH) has a profound impact on the identity and sexuality of the women who live with the disease, a new study reports. The study, “Sexual and Reproductive Health in Women with Pulmonary Hypertension: A Qualitative Study,” was published in Archives of Sexual Behavior. The impact…

Hospital-based administrative data can be used to identify patients with pulmonary hypertension (PH) in medical records, according to a study done in Canada. These results, if validated, would pave the way for advances in the screening and treatment of PH, and help investigators improve epidemiological research into this rare…

Among people who have had a heart attack, those with pulmonary hypertension (PH) are at high risk of heart failure, according to a new study. The study, “Clinical impact of pulmonary hypertension on the outcomes of acute myocardial infarction patients with or without chronic obstructive pulmonary…

Measuring levels of protein sLR11 in the blood could be useful in testing for pulmonary hypertension (PH) in people who have heart failure, according to a new study. The study, “Circulating sLR11 levels predict severity of pulmonary hypertension due to left heart disease,” was published in…

The use of imaging to evaluate the right side of the heart could be useful for non-invasively diagnosing and monitoring pulmonary arterial hypertension (PAH) in people with connective tissue diseases, according to a new study. The study, “Evaluation of pulmonary arterial pressure in patients with connective…
