Comparing a ct scan of lung arteries with a heart catheterization for pulmonary hypertension
Part of Heart & circulation, Lungs & breathing clinical trials.
This study looks at whether a special CT scan of the lungs (CT pulmonary angiography) can give results similar to a more invasive heart catheterization test for measuring blood pressure in the lungs. It may help doctors diagnose and monitor pulmonary hypertension more easily in the future.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You must have a confirmed type of pulmonary hypertension called 'pre-capillary' (high pressure in the lungs' arteries with normal pressure in the heart's left side).
- Your pulmonary hypertension must be classified as Group 1 (PAH), Group 3 (due to lung disease/low oxygen), or Group 4 (chronic blood clots in the lungs).
- You must have had both a CT scan of the lungs and a right heart catheterization within a 4-week period.
- You must not be pregnant, have active cancer, or have severe kidney problems (eGFR below 30) or a history of severe contrast allergy.
- You must not have started or increased any pulmonary vasodilator medications within the 4 weeks before the CT scan or in between the two tests.

This trial tests if using ultrasound to guide a catheter into the lung's blood vessels is a good way to diagnose pulmonary hypertension. It may help find a safer, more accurate method for diagnosis.
This study looks at how heart failure affects blood vessels in the lungs. If you have heart failure with reduced pumping ability and need a heart catheterization, you may be able to join.
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 study aims to better understand how COPD affects the blood vessels in your lungs by looking at measurements from a right heart catheterization. It may help doctors identify a specific pattern of lung and heart problems in people with COPD.
This study observes people who are already scheduled for a right heart catheterization, a procedure that checks the pressure in your heart. It helps doctors learn more about heart conditions without adding any extra treatments or procedures.
This trial tests an inhaled medicine that may help people with lung scarring or connective tissue disease who have high blood pressure in the lungs only during exercise. It aims to improve their ability to be active and reduce symptoms.
