Lower radiation dose for routine heart catheterization
Part of Heart & circulation clinical trials.
This study compares usual radiation dose with a lower dose during routine heart catheterizations (diagnostic angiograms) for people whose heart arteries turn out to be normal. It aims to see if lower-dose imaging still provides good pictures while reducing radiation exposure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need to be an adult (18 years or older) who is scheduled for a diagnostic angiogram (a test to look at the heart's blood vessels).
- Your heart arteries must appear normal during the test (no blockages found).
- You may qualify if you need an angiogram before heart valve surgery, after a positive stress test, or for other reasons like symptoms with an abnormal ECG or a high risk before a transplant.
- You cannot have a current or recent heart attack (STEMI or NSTEMI).
- You must be willing to take part in the study.

This trial tests a non-invasive method to detect narrowing in the heart's arteries. It may help people with suspected stable coronary artery disease avoid more invasive tests.
This study tests a new way to use CT scans to look at both the structure of your heart arteries and how well blood flows through them. It may help doctors get a more complete picture of coronary artery disease without extra procedures.
This study tests a new way to use less radiation during a heart catheter procedure (coronary angiography). The goal is to see if it's safe and effective.
This trial tests a new way to reduce the amount of radiation you receive during a heart procedure (like angioplasty or stenting) done through the wrist. It aims to make the procedure safer for patients and staff.
This trial tests a new CT scanner (photon-counting CT) combined with a tiny camera inside the heart arteries to better see blockages. It's for people with chest pain or silent ischemia, but not for those having a big heart attack (STEMI) or with unstable conditions.
This study compares two ways of guiding a heart stent procedure: using information from a special angiography scan versus using standard practice. It may help your care team choose the best treatment to improve heart outcomes after stenting.
