Investigating immediate versus delayed coronary angiography for cardiac arrest patients

Official title: Direct or Subacute Coronary Angiography in Out-of-hospital Cardiac Arrest - a Prospective, Randomized Study

Run by Uppsala University · NCT02309151 · Data updated 2026-05-14

This study is no longer in our active list. It may have stopped recruiting or finished. The details below are as of 2026-05-14 and are kept for reference. Check ClinicalTrials.gov for its current status, or see similar studies below.

This study is testing if doing heart imaging right after a cardiac arrest can help people survive longer compared to waiting a few days to do the imaging.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults who have experienced a witnessed out-of-hospital cardiac arrest with restoration of spontaneous circulation lasting more than 20 minutes and no ST-elevation on their ECG.

Probably not a fit

Patients under 18 years old, those with ST-elevation on ECG, or those with obvious extracardiac causes of cardiac arrest will not benefit from this study.

What this trial studies

This prospective, randomized study aims to determine if performing acute coronary angiography within 120 minutes improves 30-day survival rates in patients who experience out-of-hospital cardiac arrest without ST-elevation on their ECG after restoration of spontaneous circulation. Participants will be randomly assigned to receive either immediate coronary angiography or delayed angiography, which may occur three days post-arrest. The study will include 1006 patients and will assess quality of life and health economics at six months, alongside extensive neurocognitive testing.

Why it matters

Potential benefit: If successful, this study could significantly improve survival rates for patients experiencing out-of-hospital cardiac arrest.

How similar studies have gone: Previous studies have explored similar approaches, but this specific strategy of immediate versus delayed angiography in this patient population is novel.
