Cardiac arrest & resuscitation
Diagnostic test accuracy of life-threatening electrocardiographic findings (ST-elevation myocardial infarction equivalents) for acute coronary syndrome after out-of-hospital cardiac arrest without ST-segment elevation
Authors' conclusion
The DTA of STEMI equivalents for the diagnosis of ACS was low among patients with OHCA.
Study context
- Population
- Adults ≥18 y with non-traumatic out-of-hospital cardiac arrest (OHCA) and VF or pulseless VT who achieved return of spontaneous circulation (ROSC), without ST-segment elevation or complete LBBB, who underwent electrocardiographic (ECG) and coronary angiography; registry 2012–2017
- Comparison
- ST-elevation myocardial infarction (STEMI) equivalents on post-ROSC ECG for diagnosis of acute coronary syndrome (ACS)
- Outcome
- Diagnostic test accuracy of STEMI equivalents for ACS
- Follow-up
- After ROSC
