Emergency coronary angiography in out-of-hospital cardiac arrest patients without STEMI.

Current guideline recommends that immediate coronary angiography (CAG) should be considered in all postcardiac arrest patients in whom acute coronary syndrome is suspected. In the setting of out-of-hospital cardiac arrest (OHCA), obtaining clinical data such as chest discomfort and medical diseases associated with acute coronary syndrome can be difficult. Therefore, emergency physicians depend on electrocardiographic findings after return of spontaneous circulation (ROSC) when they have to decide whether emergency CAG should be performed. In clinical practice, the usefulness of emergency CAG evaluation of OHCA patients without ST-segment elevation myocardial infarction is debatable. We describe 2 OHCA patients who did not exhibit ST-segment elevation after ROSC and received underwent emergency CAG.
