Lower levels of apolipoprotein A-I (ApoA-I), a component of high-density lipoprotein (HDL), or “good cholesterol,” is a significant predictor of mortality in people with pulmonary arterial hypertension (PAH), a study suggests. “Our study identified the significance of ApoA-I as a biomarker for predicting the survival outcome of PAH patients,”…

The activation of clinical sites for a global Phase 3 study to evaluate Gossamer Bio’s inhaled seralutinib (GB002), an investigational treatment for pulmonary arterial hypertension (PAH), is proceeding ahead of schedule. Clinical locations in the study, dubbed PROSERA (NCT059345260), are expected to open by the end of…

Four proteins related to a pro-inflammatory signaling molecule called TNF-alpha may serve as biomarkers to predict mortality in adults with pulmonary hypertension (PH) caused by left heart failure, a new study shows. Elevated blood levels of two such proteins, both belonging to the TRAIL family, correlated with most standard…

Researchers have identified three proteins — NID1, C1QTNF1, and CRTAC1 — in the bloodstream of people with pulmonary hypertension (PH) whose presence accurately predicted the failure of the heart’s right ventricle (RV) and related outcomes, a study reports. The proteins may serve as biomarkers to assess disease progression and…

The presence of pulmonary hypertension (PH) didn’t increase mortality after a heart transplant, according to a new study. The findings oppose earlier studies that suggested an increased mortality rate among transplant recipients with PH, which was considered a contraindication. A secondary analysis of a large transplant registry with 24…

AI Therapeutics has begun dosing in a clinical trial testing inhaled LAM-001, a potential disease-modifying therapy for pulmonary arterial hypertension (PAH). The 24-week, open-label Phase 2 study (NCT05798923) is recruiting 15 adults at Brigham and Women’s Hospital in Boston, Massachusetts. All participants should have advanced PAH…

Older age and high blood pressure in the pulmonary arteries raise the risk of complications with balloon pulmonary angioplasty (BPA), a second-line treatment for chronic thromboembolic pulmonary hypertension (CTEPH), a study suggested. If high blood pressure persists after surgery to remove the pulmonary arterial blood clots that cause…

Exposure to air pollutants significantly increased the risk of pulmonary hypertension (PH), according to a U.K. population study that included almost 500,000 people. Previous or current smoking increased PH risk and mortality even further, suggesting a synergistic relationship, the researchers noted. The large-scale study, “Dynamic association…

Persistent exercise intolerance in pulmonary arterial hypertension (PAH) patients with treatment-related improvements in blood pressure was associated with impaired muscle function and strength, a study revealed. Because many of the study’s participants have lived with PAH for many years, muscle function may have been compromised, the researchers noted. Interventions…

Molecular differences are evident between infants with severe bronchopulmonary dysplasia (BPD) and pulmonary hypertension (PH) and those with severe BPD but not PH, a pilot study that used an integrated analysis of gene activity and protein production reported. PH is a common complication of BPD, a breathing disorder in…

Infants with persistent pulmonary hypertension of the newborn (PPHN) who have blood type O responded better to inhaled nitric oxide (iNO) vasodilator therapy than those with other blood types, a small study reported. PPHN newborns with blood type A showed a similar response to type O newborns, while the…

Oral Uptravi (selexipag) provided similar clinical benefits for adults with connective tissue disease (CTD) associated with pulmonary arterial hypertension (PAH) as for those without CTD, according to a health claims database analysis. PAH patients with CTDs treated with Uptravi in real-world settings had similar risks of disease progression…
