PH has no effect on mortality in heart transplant: Study

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 begins dosing in Phase 2 trial of LAM-001

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…

Balloon pulmonary angioplasty can pose risks for CTEPH patients

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…

Air pollution exposure linked to PH, UK population study shows

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…

Muscle strengthening may complement PAH therapies

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…

PAH patients with or without CTD benefit similarly from Uptravi

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…

Self-compassion linked with anxiety, depression in PH: Study

Self-compassion, the act of being kind to oneself, was a significant predictor of anxiety and depression in adults with pulmonary hypertension (PH), a questionnaire-based study reported. Self-compassion also predicted the burden of those who care for patients. The findings suggest psychological and supportive interventions that build self-compassion are needed…

Left heart dysfunction poses great risk for CTEPH patients: Large study

Researchers have identified a significant risk factor that affects the prognosis of people with chronic thromboembolic pulmonary hypertension (CTEPH) in a large 26-year study. They found that elevated left ventricular filling pressure (LVFP), a measure of left heart function, was common in patients and predicted worse outcomes. Pulmonary hypertension…

Macitentan and tadalafil combo may be better than either drug alone

An investigational once-daily therapy, a single tablet combining macitentan and tadalafil, significantly improved pulmonary blood flow compared with macitentan or tadalafil alone in pulmonary arterial hypertension (PAH) patients taking part in the Phase 3 A DUE study. Because these medications target different PAH-related pathways, current guidelines recommend initially treating…
