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.
