Summary
This trial aims to use MRI to create biomarkers for pulmonary arterial hypertension & track disease progression & response to therapy.
Who is the study for?
This trial is for adults aged 18-75 with Pulmonary Arterial Hypertension (PAH), either idiopathic or associated with connective tissue disease. Participants must have specific heart and lung pressure measurements, be in WHO functional class 2 or 3, and not have other causes for PAH. Those unable to undergo a 129Xe MRI scan or with different types of pulmonary hypertension are excluded.
What is being tested?
The study tests the use of a special type of MRI scan using hyperpolarized Xenon gas (129Xe) as a way to identify different subtypes of PAH and monitor changes over time in response to treatment. It will be used alongside other assessments like blood tests, echocardiograms, and walking distance measures.
What are the potential side effects?
While the description does not specify side effects related to the intervention directly, typical MRI-related side effects could include discomfort from lying still during the procedure or noise during scanning. The use of hyperpolarized Xenon should be safe but may carry minimal risks which will be monitored.
