Heart Blood Flow Imaging Study for Mild Blockages
Part of Heart & circulation clinical trials.
This study tests a new way to measure blood flow in the heart using a special SPECT/CT scan. It is for people who have mild to moderate blockages in their heart arteries and may benefit from more detailed imaging to guide their treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You have had a heart scan or catheterization showing mild to moderate blockages (less than 50% narrowing) or blockages that need further testing.
- You do not have severe blockages that need immediate treatment like stenting or bypass surgery.
- You have never had angioplasty, stenting, or bypass surgery.
- Your heart's pumping strength is 35% or higher.
- You are not pregnant or breastfeeding.

Other trials that look related to this one.
This trial tests whether combining two advanced imaging tests (FFR and OCT) can help doctors better decide treatment for moderate blockages in heart arteries. If you have stable chest pain or a positive stress test and a moderate narrowing, this study may help guide your care.
This trial compares two heart imaging tests (SPECT and coronary CTA) to see if a newer method gives a clearer picture of blood flow. If you have been referred for one of these tests, you may be able to help by also having the other test done at no extra risk.
This trial looks at people with a blockage in a heart artery of 50% or more. It tests a new way to check the blockage using a special CT scan. This could help decide the best treatment to prevent future heart problems.
This trial studies a heart scan medicine (99mTc-ECDG) to help evaluate coronary artery disease, a condition caused by narrowed heart arteries. It compares how well the scan works and looks at safety while you undergo standard heart stress imaging.
This study tests if breathing in carbon dioxide can help doctors see how well blood flows to your heart muscle. It is for people with known or suspected heart disease who already had a scan showing reduced blood flow.
This trial uses a special heart MRI to measure blood flow and predict if arteries are blocked. It may help decide if you need a catheter procedure to open blockages.
