One-Year Outcomes of Coronary Angiography after Cardiac Arrest without ST Segment Elevation. Results of the COACT trial

Presented during the AHA Scientific Sessions 2019 by Jorrit Lemkes (Amsterdam, The Netherlands).

Introduction and methods

Guidelines recommend immediate coronary angiography with PCI in patients presenting with STEMI and cardiac arrest. In patients with cardiac arrest and non-ST elevation MI, guidelines recommend emergency angiography, but evidence from RCTs is lacking.

The COACT trial was a randomized trial that examine whether immediate angiography was associated with improved survival when compared to delayed angiography in 552 patients successfully resuscitated from out of hospital cardiac arrest in the absence of ST segment elevation. The primary endpoint of survival at 90 days was not different between groups (64.7% for immediate angiography and 67.2% for delayed angiography). However, effects of early angiography on long-term outcomes are unknown and observational studies suggest that early CABG results in benefits on long-term mortality.

This study examined the survival in the immediate angiography group vs. the delayed angiography group after 1 year. Only 3 patients were lost to follow-up.

Main results


In patients after cardiac arrest without signs of STEMI, immediate coronary angiography did not result in improved survival at 1 year compared to delayed angiography.
