Cellular Energy Production Different in PAH and CTEPH, Study Finds

Metabolic differences affecting energy production were observed in endothelial cells — the cells that line blood vessels — from patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). These distinctions could underlie differences in disease mechanisms and necessary treatment approaches, according to a recent study.

Rare Disease Day Events Bring Awareness, Equity to Patients

Since 2008, Rare Disease Day — the last day of February — has brought together patients, caregivers, family members, friends, and advocates from around the world to raise awareness and improve equity for the more than 7,000 known rare diseases that affect more than 300 million people. In 2022, the…

Researchers Test Prognostic Value of Breathing Reserve

Breathing reserve, a measure of lung function calculated during exercise, predicted survival in adults with congenital heart disease associated with pulmonary arterial hypertension (PAH), a study reported for the first time. Breathing reserve assessment in other diseases affecting blood vessels in the lungs also may predict survival outcomes, the…

Cardio Exercise Test May Not Be Needed to Predict PH Outcomes

A passive leg raise is equally as effective as exercise in measuring pulmonary vascular distensibility, a physiological marker to predict outcomes in people with pulmonary hypertension (PH), a study suggests. This finding is important for patients who cannot exercise or do not have access to clinical exercise facilities, the…

Genetic Testing Leads to Improved Prognosis for Woman With Rare PAH

Identification of mutations in the ATP13A3 gene, which are associated with a severe form of pulmonary arterial hypertension (PAH), led doctors to select a riskier treatment approach for a 21-year-old woman to prevent her symptoms from worsening, according to a case study. “Short-term follow-up is encouraging, and the patient…
