Summary
This study involves 100 people with suspected pulmonary hypertension who are already scheduled for a right heart catheterization. During the procedure, doctors will take two extra blood samples from a specific position in the lung artery to analyze oxygen and other gas levels. The goal is to better understand different types of pulmonary hypertension and potentially guide future treatments.
