Early coronary angiography in patients resuscitated from out of hospital cardiac arrest without ST-segment elevation: A systematic review and meta-analysis

The results of our meta-analysis support the use of early coronary angiography in out of hospital cardiac-arrest patients presenting without ST-segment elevation on the post-resuscitation electrocardiogram. However, given the low level of evidence of available studies, future guideline changes should be directed by the results of large-scale randomized clinical trials on the subject matter.
