Summary of guidelines on the role of coronary angiography in patients with out-of-hospital cardiac arrest^a

Guideline	Postresuscitation ECG with ST-segment elevation	Postresuscitation ECG without ST-segment elevation
2017 ESC Guidelines for the management of acute myocardial infarction in patients presenting with ST-segment elevation8	IB recommendation: primary PCI strategy recommended	IIa C: urgent angiography (and PCI if indicated) should be considered for patients with high suspicion
2019 SCAI expert consensus statement on out-of-hospital cardiac arrest6	For select comatose patients with OHCA: definite invasive strategy	Defer invasive strategy at initial encounter in hemodynamically stable comatose patients
2020 ILCOR Consensus on Science: American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care9	COR 1 (LOE B-NR): CAG should be performed emergently for all patients with a suspected cardiac cause of arrest	COR 2a (LOE B-NR): Emergency CAG is reasonable in select (such as electrically or hemodynamically unstable) comatose patients with a suspected cardiac cause of arrest

CAG, coronary angiography; COR, classification of recommendation; ECG, electrocardiogram; ESC, European Society of Cardiology; IB, Class I recommendation with level of evidence B; IIa C, Class IIa recommendation with level of evidence C; ILCOR, International Liaison Committee on Resuscitation; LOE, level of evidence; OHCA, out-of-hospital cardiac arrest; PCI, percutaneous coronary intervention; SCAI, Society for Cardiovascular Angiography and Interventions.
