Abstract

Purpose

To investigate whether early coronary angiography (CAG) after out-of-hospital cardiac arrest of a presumed cardiac cause is associated with improved outcomes in patients without acute ST elevation.

Methods

The target temperature management after out-of-hospital cardiac arrest (TTM) trial showed no difference in all-cause mortality or neurological outcome between an intervention of 33 and 36 °C. In this post hoc analysis, 544 patients where the admission electrocardiogram did not show acute ST elevation were included. Early CAG was defined as being performed on admission or within the first 6 h after arrest. Primary outcome was mortality at the end of trial. A Cox proportional hazard model was created to estimate hazard of death, adjusting for covariates. In addition, a propensity score matched analysis was performed.

Results

A total of 252 patients (46 %) received early CAG, whereas 292 (54 %) did not. At the end of the trial, 122 of 252 patients who received an early CAG (48 %) and 159 of 292 patients who did not (54 %) had died. The adjusted hazard ratio for death was 1.03 in the group that received an early CAG; 95 % CI 0.80–1.32, p = 0.82. In the propensity score analysis early CAG was not significantly associated with survival.

Conclusions

In this post hoc observational study of a large randomized trial, early coronary angiography for patients without acute ST elevation after out-of-hospital cardiac arrest of a presumed cardiac cause was not associated with improved survival. A randomized trial is warranted to guide clinical practice.

Take-home message: In an observational study within a multicenter international randomized trial of OHCA of presumed cardiac cause, early coronary angiography was not associated with increased survival or neurological outcome when the admission ECG did not show acute ST segment elevation.
