Testing a heart-pressure ratio to choose bypass surgery plan
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be age 18 or older and planning to have coronary bypass surgery (CABG)
- Be able and willing to sign written informed consent
- Have no prior heart bypass surgery (no previous CABG)
- Your heart pumping strength must be enough (left ventricular ejection fraction 30% or higher)
- There must not be very low blood-vessel function or severe issues: no known microvascular disease, no “across-the-wall” (transmural) heart attack, and doctors must be able to take the ratio measurement (RFR/FFR)

This trial uses a special pressure wire called RFR to help doctors decide whether a stent is needed for a moderate heart artery blockage. It aims to make sure only the blockages that really need treatment get stented, which may reduce unnecessary procedures.
This study follows people who have narrowed heart arteries and have a pressure test (FFR) to guide treatment. It may help doctors understand the course of disease when using FFR and choosing a minimally invasive approach.
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 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 trial checks if a new way of measuring blood flow during heart bypass surgery helps improve outcomes. It's for people having planned (not emergency) bypass surgery for certain types of chest pain or heart attack.
This trial compares two ways to decide how to treat a narrowed “left main” coronary artery: a pressure-based test (FFR) versus standard X-ray imaging (angiography). It aims to see which approach better helps choose safe, appropriate treatment using a stent when appropriate.
