Researchers are studying blood samples taken during a heart catheterization procedure — a test you may already need if your doctor suspects you have high blood pressure in your lungs. By analyzing two small blood samples (about 4 milliliters total) collected at a specific point during this procedure, doctors hope to better understand different types of this lung condition and eventually develop better treatments.
Pulmonary hypertension — high blood pressure in the lungs — can develop for many different reasons, and doctors don't yet have a clear way to tell these different types apart. This study aims to gather new information that could help doctors diagnose patients more accurately and create targeted treatments for specific groups in the future.

If you join this study, you will be getting a right heart catheterization procedure that your doctor has already recommended. During that procedure, the research team will collect two small blood samples (taken at the beginning and again two minutes later) from a specific location inside your heart's blood vessels. You will also answer questions about your medical history and any other health conditions you have. After your procedure, doctors will follow your health progress and look for patterns in your blood test results.
