Children with episodes of fainting due to pulmonary arterial hypertension (PAH) who respond well to a vasodilator given in a challenge test are likely to have better long-term outcomes than those who respond poorly, a long-term records study suggests. A vasodilator challenge is a test to measure blood pressure in…
A blood test for angiopoietin-2 (Ang-2), a protein associated with forming new blood vessels, may predict treatment outcomes in people with chronic thromboembolic pulmonary hypertension (CTEPH), a study showed. Researchers found that the protein’s level was significantly higher in the bloodstream of patients with this rare form of…
Up to two years of treatment with sotatercept safely maintained gains in heart function and physical abilities in people with pulmonary arterial hypertension (PAH), according to details of the PULSAR study extension phase. Further, participants who were initially assigned a placebo in the Phase 2 controlled trial, and switched…
A protein called LTBP-2 was found to be significantly elevated in people with pulmonary arterial hypertension (PAH), according to a new analysis — and the data suggest that measuring its levels may help predict long-term survival among PAH patients. Further, blood levels of LTBP-2 were also able to predict…
Extracellular vesicles derived from mesenchymal stem cells eased the signs and symptoms of pulmonary hypertension (PH) in a rat model of bronchopulmonary dysplasia (BPD), a study shows. BPD is one of the most common complications in prematurely born infants who need supplemental oxygen and is marked by airway damage…
Mixed venous oxygen tension (PvO2) — a measure for tissue oxygenation — is a significant predictor of outcomes in pulmonary hypertension (PH), a study suggested. Specifically, lower PvO2 was significantly associated with poor outcomes in people with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH),…
Elevated metabolites of the kynurenine pathway in the bloodstream of people with pulmonary arterial hypertension (PAH) when they’re diagnosed predicted disease severity, their response to therapy, and survival, a study discovered. Activation of the kynurenine pathway, related to vitamin B3 production, was found to be linked to…
Higher levels of the metal antimony were found in the bloodstream of adults with pulmonary arterial hypertension (PAH) than those without the condition, a pilot study reported. Elevated antimony levels also correlated with higher blood pressure in the pulmonary arteries and reduced heart function. The pilot study, “Plasma…
Hyaluronic acid, a major component of the extracellular matrix that supports cell function, directly contributes to the development of pulmonary hypertension (PH) via pulmonary vascular remodeling, a preclinical study has found. By pharmacologically blocking the production of the substance in a PH mouse model, researchers were able to prevent…
Seralutinib (GB002), an investigational inhaled treatment for pulmonary arterial hypertension (PAH), effectively treated severe disease in two animal models, a study demonstrated. Further, when compared directly, inhaled seralutinib showed greater efficacy than imatinib, an approved cancer therapy also being investigated for PAH. Gossamer Bio, seralutinib’s developer, now is testing…
People with pulmonary hypertension (PH) who were diagnosed with COVID-19 had a high rate of hospitalization and in-hospital mortality, a French study concluded. Risk factors for adverse outcomes included being older, male, having co-existing conditions, or comorbidities, and having more severe PH. Anticoagulants (blood thinners) were the only treatment…
Sacubitril/valsartan, a fixed-dose combination oral therapy approved for heart failure, was found to improve right heart function and lower pulmonary blood pressure, according to a new pooled analysis of multiple studies. This meta-analysis supports a new therapeutic role for sacubitril/valsartan for people with pulmonary hypertension (PH) associated with heart…
