Summary

This study looks at why people with pulmonary arterial hypertension (PAH) lose muscle mass and how that affects their daily life and activity. Researchers will measure body composition, heart fat, diet, and physical function in 150 adults with PAH. No new treatment is being tested; the goal is to better understand muscle loss to guide future therapies.
