Abstract 10989: Diagnostic Impact Of Electrocardiogram And Emergency Coronary Angiography In Patients With Out-of-hospital-cardiac-arrest
Objective: The guideline suggests that coronary angiography (CAG) should be performed for the patients with out-of-hospital-cardiac-arrest (OHCA) and return of spontaneous cardiac arrest (ROSC). We investigated the association between initial ST-segment change after ROSC and incidence of acute coronary lesion in patients with OHCA. We also researched the number of patients with OHCA caused by vasospastic angina pectoris (VSA).
Methods: From April 2011 to March 2015, there were 2,779 OHCA patients in our institution. We underwent CAG for all patients with ROSC, except for obvious extra-cardiac cause of OHCA. Initial ST-segment change after ROSC of serial 155 patients(61±14.5years old,83.9% male) was reviewed.
Results: The 34% of patients had ST-segment elevation and the 66% had other electrocardiogram (ECG) pattern. Significant coronary lesion which needs percutaneous coronary intervention (PCI) was shown in the 81% of patients with ST-segment elevation and in 33% with other ECG (P<0.001). ST-segment analysis had a good positive predictive value (81%) but a low negative value (68%) in diagnosing the presence of acute coronary lesions. The patients who were diagnosed vasospastic angina were found in the 10% of patients with ST-segment elevation and in the 12% with other ECG.
Conclusion: Even in the absence of ST-segment elevation, acute culprit coronary lesion may be present, and there is significant value to perform emergency CAG for ROSC patients. Furthermore, vasospastic angina pectoris may be present and considered the trigger of cardiac arrest. Emergency CAG could remove the coronary artery spasm by directly NO injection.
