Summary

This study looked at 212 patients who woke up after a cardiac arrest outside the hospital. Researchers compared getting a heart angiogram right away versus waiting 12-24 hours. The goal was to see if immediate imaging reduces the risk of death, shock, or another cardiac arrest. The study was stopped early, so results are limited.
