Summary

This trial is studying how disease progression and treatment affects changes in gas exchange and blood flow in people with pulmonary arterial hypertension.

Who is the study for?
This trial is for adults aged 18-75 with Pulmonary Hypertension (PH), specifically those who are newly diagnosed or have started treatment within the last three months. Participants must be able to consent and follow the study schedule, and women of childbearing age need a negative pregnancy test before MRI scans. Those awaiting lung transplants can join too, but not if they have severe liver disease, heart issues, active cancer, sickle cell anemia or conditions preventing MRI use.Check my eligibility
What is being tested?
The trial is testing how a type of imaging called Xenon 129 Magnetic Resonance Imaging (MRI) can show changes in lung function and blood flow in patients with different types of Pulmonary Hypertension. It aims to understand how these images change with disease progression or after starting treatment.See study design
What are the potential side effects?
Since this trial involves MRI scanning using hyperpolarized Xenon gas rather than drug interventions, typical side effects associated with medications may not apply. However, there might be risks related to lying still during the scan or reactions to inhaling Xenon gas.

Prior Approvals
Other Research
Common treatments for Pulmonary Hypertension (PH) include phosphodiesterase-5 (PDE5) inhibitors, endothelin receptor antagonists (ERAs), and prostacyclin analogs. PDE5 inhibitors increase cyclic GMP levels, leading to vasodilation and reduced pulmonary artery pressure. ERAs block endothelin-1, a potent vasoconstrictor, reducing vascular resistance. Prostacyclin analogs promote vasodilation and inhibit platelet aggregation. These treatments are crucial for PH patients as they improve pulmonary blood flow, enhance oxygenation, and improve quality of life and survival.
