Vitamin D and hormone levels in pulmonary hypertension

This study tracks natural changes in “biomarkers” (measurable signals in blood) and imaging findings in people with pulmonary arterial hypertension (PAH) or suspected PAH. It also includes healthy people for comparison, helping researchers understand what these signals mean over time.

This observational study is looking at people diagnosed with pulmonary hypertension to better understand how it behaves over time. You may help researchers by allowing repeated check-ins for years and sharing symptom and test information.

This study collects blood samples and medical information from people with pulmonary hypertension (high blood pressure in the lungs) to help researchers better understand the condition and develop new treatments. Your participation involves providing a blood sample and allowing researchers to access your health information.

This study looks at the genes that may be linked to pulmonary hypertension. By providing a saliva sample and filling out a health survey from home, you can help researchers learn more about this condition.

This study looks at lung tissue from people having chest surgery to understand why some lung diseases lead to high blood pressure in the lungs (pulmonary hypertension). You may be eligible if you're having lung surgery or are on the lung transplant list.

This study builds a medical and symptom database for people who have pulmonary hypertension or may be at risk, to better understand the condition. If you choose to participate, your basic health information and symptom history may be recorded and used for research.
