To evaluate the predictive value of EEG reactivity assessment and confounders for neurological outcome after cardiac arrest. ⋯ After cardiac arrest, absence of EEG reactivity was predictive of unfavorable outcome. By contrast, a benign EEG was slightly predictive of a favorable outcome. Reactivity assessment may have important implications in the neuroprognostication process after cardiac arrest and could be influenced by sedation.

Outcome prediction in comatose patients following cardiac arrest remains challenging. Here, we assess the predictive performance of electroencephalography-based power spectra within 24 h from coma onset. ⋯ On the first day of coma following cardiac arrest, low power spectra values around 10 Hz, typically linked to impaired cortico-thalamic structural connections, are highly specific of unfavourable outcome. Peaks in this frequency range can predict long-term outcome.

There is no simple clinical tool that reliably indicates the presence of acute coronary lesions in out-of-hospital cardiac arrest (OHCA) patients without typical ST-segment elevations. ST-segment elevation in electrocardiographic lead aVR suggests global subendocardial ischemia. This study aimed to evaluate the diagnostic value of lead aVR for identifying acute coronary lesions following resuscitation from OHCA. ⋯ ST-segment elevation in lead aVR at early follow-up was associated with the presence of acute lesions accompanied by severe coronary artery disease in post-cardiac arrest patients without other ST-segment elevations. The analysis of ST-segment elevation in lead aVR may aid in the identification of patients who will benefit from further invasive coronary diagnostic procedures.
