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…

People with both pulmonary hypertension (PH) and interstitial lung disease (ILD) have worse survival outcomes than ILD patients who don’t have PH, a study has found.  Lung function and blood flow tests were important predictors of overall survival in this patient population, according to the study, “…

An increase in right atrial blood pressure during exercise in people with pulmonary hypertension (PH) reflects problems with blood flow in the heart and is linked to a worse prognosis and higher mortality, a study shows. Researchers therefore suggest that right atrial blood…

Off-label use of prostacyclin therapy successfully treated five newborns with persistent pulmonary hypertension of the neonate (PPHN), and switching from intravenous infusion to subcutaneous injection was well tolerated, a case series reported.  Its authors recommend larger studies to…

New variants in the DNA region that promote the activity of the BMPR2 gene — associated with familial pulmonary arterial hypertension (PAH) — lower the gene’s activity and may contribute to the condition in some families, a study…

Elevated levels of the protein IGFBP2 were identified in the blood of people with pulmonary arterial hypertension (PAH) and found to be associated with lower physical function, higher arterial blood pressure, and an increased mortality risk, a study reports.  …

For the first time, the long-term use of antipsychotic medications has been linked to the development of chronic thromboembolic pulmonary hypertension (CTEPH), a case study reports.  The authors recommend that CTEPH should be considered in patients who receive antipsychotics and also have symptoms associated…

Adults with chronic thromboembolic pulmonary hypertension (CTEPH) experience more breathing stoppages during sleep (apnea), lower blood oxygen, and higher levels of pro-inflammatory proteins in the blood than people with idiopathic pulmonary arterial hypertension who…

Volibris (ambrisentan) given to treat adults in China with pulmonary arterial hypertension (PAH) caused by connective tissue disease led to significant improvements in exercise capacity without signs of clinical worsening over 24 weeks, a study reported. Improvements were…

A case report found a patient’s pulmonary arterial hypertension (PAH) was caused by an undiagnosed case of the autoimmune disorder systemic sclerosis (SSc), highlighting the need for early and thorough diagnostic workups, researchers say. The 77-year-old woman’s PAH was also worsened by other conditions, including lung…
