Measuring heart artery resistance during angiography
Part of Heart & circulation clinical trials.
This trial tests a new way to measure resistance in the heart's small and large arteries during a standard angiogram. It may help doctors better understand and treat blockages or microvascular disease.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have chest pain or a recent heart-related event and need a heart catheterization.
- Your doctor plans to check blood flow in your arteries using standard pressure measurements.
- You have a blockage (30-90% narrowed) or very mild narrowing (less than 30%) in your heart arteries.
- You have not had a heart attack or stent placed in the same artery being tested in the last year.
- You have not had bypass surgery, valve surgery, or a heart transplant.
- Your heart function (ejection fraction) is above 45% and you are not in shock.

This study helps collect measurement data during a heart catheter procedure when coronary disease is suspected. You may be eligible if you’re having a catheter-based evaluation and doctors plan to assess blood flow to determine how severe a new heart blockage is.
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.
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 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 trial tests if special software can check the result of a balloon or stent procedure by looking at the X-ray movie of your heart arteries. It may help doctors decide if more treatment is needed.
This study looks at how to personalize treatment for people with angina (chest pain) by measuring how well blood flows through the heart’s small vessels and the main arteries during a procedure. It may help doctors choose the right approach after your coronary angiography (heart artery imaging).
