AbstractOut-of-hospital cardiac arrest is a relatively common event. Acute coronary thrombotic events are the main trigger of sudden cardiac arrest. Mortality of patients, in whom return of spontaneous circulation is obtained, is still high, mainly due to anoxic brain injury and progressive cardiac failure. In the last years, the implementation of "post-cardiac arrest care" led to a significant improvement of hospital survival of these patients. Mild therapeutic hypothermia has become the foundation for improvement of survival with good neurological outcome after cardiac arrest. Recently, there is a growing interest in emergent invasive coronary strategies, including emergent coronary angiography and subsequent percutaneous coronary interventions when indicated. Emergent coronary angiography is strongly recommended in patients with ST-segment elevation on the ECG performed after return of spontaneous circulation. Conversely, whether patients without ST-segment elevation on ECG or patients who remain unconscious after return of spontaneous circulation should always undergo emergent coronary angiography is still unclear. Recent observational stud ies have shown that emergent invasive coronary strategies may improve hospital survival also in this patient subset. This suggests that resuscitated cardiac arrest victims without an obvious non-cardiac etiology should always undergo emergent coronary angiography, in association with therapeutic hypothermia if indicated.
