 Cardiac arrest is a major public health issue. Arizona has been a leader in improving long-term survival by introducing new and innovative resuscitation approaches including Chest Compression-Only CPR and Cardiocerebral Resuscitation. Post-resuscitation care is the next great opportunity for further improvements. Early coronary angiography CAG combined with therapeutic hypothermia has become the recommended standard of care for post-cardiac arrest patients manifesting ST segment elevation on their electrocardiogram ECG. However, the majority of cardiac arrest victims do not have ST segment elevation. There is clinical equipoise as to whether these patients will benefit from early CAG.
