NCT ID NCT02309151

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

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) within 2 hours versus waiting 3 days. The goal was to see if early imaging improves survival at 30 days. Participants had no clear signs of a heart attack on their first ECG.

What this could mean

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

Active substance

Immediate coronary angiography (a procedure to look at heart arteries with X-rays)

What this could lead to

If immediate angiography proves better, it could become the standard approach for cardiac arrest patients without clear heart attack signs, potentially saving more lives.

What could go wrong

This trial is completed but results may not show a clear benefit, and the findings might not apply to all cardiac arrest patients. The procedure itself carries small risks like bleeding or kidney injury.
