In this randomized clinical trial, for patients who experience an out-of-hospital cardiac arrest (OHCA) without ST-segment elevation on ECG, a strategy of emergency CAG was not better than a strategy of delayed CAG with respect to 180-day survival rate and minimal neurologic sequelae.

The study was stopped early due to insufficient enrollment.

Investigators enrolled approximately 280 patients out of 970 planned.

Studies stopped early can overestimate results.

While the study provides interesting data, it’s underpowered, and we cannot draw firm conclusions.

The study findings are similar to those reported in TOMAHAWK (Desch 2021), COACT (Abella 2019), and PEARL (Lemkes 2019) trials.
