Summary

This study is creating a large collection of blood samples and medical information from 1000 adults with or suspected of having pulmonary hypertension (PH). Researchers hope this resource will help them find new ways to diagnose and treat PH. Participants will provide a blood sample and allow access to their medical records, with optional follow-up visits.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this biorepository could help researchers discover new biomarkers and improve diagnosis and treatment for pulmonary hypertension.
What could go wrong
This is an observational study that does not test any treatment. It may not directly lead to new therapies, and results depend on future research using the collected samples.
