Blood Flow Measurement During Heart Imaging
Part of Heart & circulation clinical trials.
This study examines how a special measurement technique works when blood vessels are dilated during a heart imaging procedure. It may help doctors better assess whether narrowing in your heart arteries needs treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have stable chest pain or suspected heart disease
- You are scheduled for a heart catheterization (coronary angiography) with blood flow testing
- Any narrowing in your target artery is less than 50%, or between 50–90% with a blood flow test (FFR) showing good flow (>0.80)
- You can provide informed consent
- You do not have acute heart attack, severe heart failure, or dangerous irregular heartbeats
- You can safely receive adenosine (a medication that dilates blood vessels) and have no severe asthma or high-degree heart blocks

This study looks at a specific heart blood-flow measurement taken during a coronary procedure to see how well it predicts future outcomes. If you had a successful pressure measurement called FFR with a tracing, your results may be analyzed to understand risk and prognosis.
This study measures how well blood flows through the heart when the heart rate is increased during a heart procedure. It may help doctors better understand coronary (heart artery) blood flow and how to guide treatment when you need angiography or angioplasty.
This study compares a new artificial intelligence (AI) method to measure blood flow in your heart arteries (called Medipixel FFR) with the standard invasive method. If you are scheduled for a heart angiogram or stenting and have a moderate blockage (40-90% narrowing) that doctors are unsure about, this AI tool may help decide the best treatment for you.
This study compares two pressure-based methods (Vessel-FFR vs standard FFR) to decide how severe a heart artery narrowing is during a coronary angiogram or PCI. It may help patients and doctors choose which narrowings need treatment more accurately.
This study tests a special heart scan that measures blood flow to the heart muscle. It may help doctors decide if your heart blockages need treatment or if medication is enough.
This study looks at how well the heart’s blood vessels work in people who have symptoms of reduced blood flow but no major artery blockage. It uses special heart tests with medicines to check how the vessels respond and may help guide better diagnosis and treatment.
