Heart bypass surgery and artery imaging study
Part of Heart & circulation clinical trials.
This study looks at whether a special imaging test called QFR, done before heart bypass surgery, can help predict how well the radial artery graft will work shortly after surgery. If you have severe blockages in your heart arteries and are scheduled for bypass surgery, this trial may be relevant.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have chest pain that limits your daily life and hasn't improved with medication, so you need heart bypass surgery.
- You have a coronary angiogram (a special X-ray of your heart arteries) available that can be analyzed with QFR technology.
- You have severe blockages (more than 70%) in at least three main heart arteries, with or without a blockage over 50% in the left main artery.
- You can safely undergo bypass surgery without urgent procedures, recent stroke, or other major health problems.

This study is for people who recently had a heart attack and need an angiogram. It looks at blockages that are not completely blocking blood flow to learn how they change over time.
This study compares two advanced imaging methods (IVUS and FFR) to see which better identifies blockages that need treatment. It may help doctors decide the best care for people with chest pain or recent heart attacks.
This trial studies whether a special heart “pressure/flow ratio” test (measured during the procedure) can help doctors choose the best plan for coronary bypass surgery. It may improve how bypass targets the problem blood vessels, but only if certain heart and health factors fit the study rules.
This trial compares two ways to plan heart bypass surgery: a CT scan that measures blood flow (CT-FFR) versus the usual heart catheter X-ray (angiogram). It aims to see which method leads to better outcomes for people with blocked heart arteries.
This study looks at tiny structures inside heart muscle cells (especially “power stations” in the cells) in people with certain types of heart failure who are getting coronary bypass surgery. It may help researchers better understand what changes happen in the heart and how this could guide future care.
This study compares two types of blood vessels used in heart bypass surgery: the radial artery (from your forearm) versus a vein (typically from your leg). Researchers want to see which graft option works better and lasts longer in women with severe heart disease.
