This study is creating a biobank to collect samples (blood, urine, and stool) from people with pulmonary hypertension (high blood pressure in the lungs), those at high risk for it, healthy individuals, and patients undergoing a right heart catheterization (a procedure to measure heart and lung pressures). The goal is to better understand pulmonary hypertension and find new ways to guide treatment. There are no interventions or treatments being tested; this is purely for collecting samples for future research. You may be able to join if you are 18 or older and have a diagnosis of pulmonary hypertension, systemic sclerosis, or mixed connective tissue disease, or are undergoing a right heart catheterization. The study aims to collect samples for 10 years.
