CT scan vs heart catheterization for lung blood pressure
Part of Heart & circulation, Lungs & breathing clinical trials.
This study looks at how well a CT scan of the lungs (called CTPA) can measure blood pressure in the lungs compared to the standard test, right heart catheterization. It may help doctors use CT scans more in the future to monitor pulmonary hypertension.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- You have been diagnosed with a certain type of pulmonary hypertension (pre-capillary PH) using a heart catheterization test.
- Your PH type is one of these: PAH, PH from lung disease, or PH from chronic blood clots.
- You had both a special CT scan of your chest (CTPA) and a heart catheterization within 4 weeks of each other.
- You do not have active cancer, are not pregnant, and have no severe kidney problems or allergy to CT dye.
- You have not started or increased your PH medications in the past month.

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 uses heart imaging tests to better understand pulmonary arterial hypertension (PAH) and predict outcomes. It may help doctors tailor treatment for people with PAH.
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 checks for a condition called pulmonary hypertension in people who have a certain type of heart failure (where the heart pumps normally but doesn't relax well). It aims to find out how common it is and what it looks like.
This study is watching people who are having their first right heart catheterization to better understand and manage lung blood pressure problems. It may help doctors improve diagnosis and treatment for people with shortness of breath or suspected pulmonary hypertension.
This trial compares two advanced CT imaging methods to check if moderate narrowing in your heart arteries is causing blood flow problems. Both methods are non-invasive (no surgery) and use CT scans to help your doctor decide if you need further treatment.
