Heart test showdown: invasive vs Non-Invasive – which is better for mild blockages?

NCT ID NCT05799092

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compares two ways to check heart arteries after a CT scan shows non-severe blockages: an invasive angiogram (a tube in the artery) versus standard non-invasive tests (like stress tests). About 2,000 people with chest pain or related symptoms will be randomly assigned to one approach. The goal is to see which strategy better prevents heart attacks, deaths, or the need for unplanned procedures.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If this trial shows that non-invasive testing is as good or better than invasive angiography, it could change standard practice, sparing many patients from unnecessary procedures.
What could go wrong
This is a diagnostic strategy trial, not a treatment study. The results may not apply to higher-risk patients, and the open-label design could introduce bias.
