First seen Apr 18, 2026 · Last updated Jun 22, 2026 · Updated 11 times
Summary
This study looked at 1,003 people who had a cardiac arrest outside the hospital and were revived. It compared getting a coronary angiogram (an X-ray of the heart's arteries) right away versus waiting three days. The goal was to see if immediate imaging improves survival at 30 days. Participants had no clear signs of a heart attack on their first ECG.

What this could lead to
If immediate angiography improves survival, it could become the standard approach for treating cardiac arrest patients without obvious heart attack signs.
What could go wrong
This trial is completed but results may not show a clear benefit, and the approach carries risks like bleeding or kidney injury from the procedure.
