New test during angiography could unlock better care for hidden heart pain
NCT ID NCT04674449
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at people with chest pain (angina) but no major blockages in their heart arteries. During a standard angiogram, doctors will perform an extra diagnostic test to see if it helps guide treatment. Half the participants will have the test results shared with their doctor, while the other half will not. The goal is to see if this approach improves symptoms, quality of life, and heart health over time.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Interventional diagnostic procedure (IDP) during coronary angiography
What this could lead to
If successful, this could show that a simple diagnostic test during angiography helps doctors choose better treatments for people with chest pain but no blocked arteries.
What could go wrong
This is an early-stage study focused on diagnosis and treatment guidance, not a cure. The test may not improve symptoms or outcomes, and there are small risks from the procedure itself.
