Rare mutations in the ATP13A3 gene caused a severe inherited form of childhood-onset pulmonary arterial hypertension (PAH), a case study of three families showed. These findings demonstrate the “growing importance” of genetic testing in patients with childhood-onset PAH, the scientists said, noting that the genetic basis of the disease…

AER-901, an inhaled formulation of imatinib being developed as a treatment for pulmonary arterial hypertension (PAH), has been granted orphan drug designation by the U.S. Food and Drug Administration (FDA). The investigational therapy was designed with the goal of reducing the side effects reported among PAH patients using an…

Routine blood screenings and non-invasive clinical tests may predict disease severity and mortality in people with pulmonary hypertension (PH), a study suggested. Specifically, the red blood cell distribution width (RDW) test, used in hematology laboratories to classify anemia, may help in assessing disease severity, while electrocardiographic ratios may predict…

The PAPi blood pressure test was able to accurately predict mortality in Asian people with pulmonary arterial hypertension (PAH), a 14-year study revealed. Despite that finding, the multi-factor REVEAL score was found to still be the best predictor for mortality risk in PAH. “In our analysis, low PAPi was…

The likelihood of developing pulmonary hypertension (PH) is low among people in southern Italy, suggests a study that draws from a random and large grouping of individuals with echocardiograms, done to determine disease prevalence. Independent predictors of PH include female sex and right ventricular enlargement, its scientists noted. The study,…

The U.S. Food and Drug Administration (FDA) has accepted an updated application asking that the dry-powder inhalation therapy LIQ861 (treprostinil) be approved to treat pulmonary arterial hypertension (PAH). Liquidia Corporation, the therapy’s developer, first…

Altavant Sciences has opened ELEVATE 2, its global Phase 2b clinical trial into the safety and efficacy of rodatristat ethyl, a potential disease-modifying oral therapy for people with pulmonary arterial hypertension (PAH). The…

Iron replacement did not affect disease severity or the ability to function in people with pulmonary arterial hypertension (PAH), an analysis of two clinical studies showed.  It also was found to have no impact on quality of life for these patients.

Diminazene aceturate (DIZE), an approved antiparasitic medication, lessened the development of pulmonary arterial hypertension (PAH) in a rat model, a study has demonstrated. These findings support further investigation of DIZE as a potential treatment for PAH, scientists said.  The…

Adipose (fat) tissue may contribute to the development of pulmonary arterial hypertension (PAH) due to certain metabolic alterations found, for the first time, in patients and also in rodent models of the condition, a study suggests. The study, “…

A gene called DNMT3B was found for the first time to be a mediator of blood vessel wall growth, and has been implicated in the development of pulmonary hypertension (PH) in a rat study. This gene, which regulates inflammatory pathways…

Elevated blood levels of the kidney disease biomarker creatinine and the heart failure biomarker NT-proBNP were found to be independent predictors of mortality for older people with pulmonary arterial hypertension (PAH) who were born with congenital heart disease…
