- Objective: Investigate the temporal development of EEG and prognosis. Methods: Prospective observational substudy of the Target Temperature Management trial. Six sites performed simplified continuous EEG-monitoring (cEEG) on comatose patients after cardiac arrest, blinded to treating physicians. We determined time-points of recovery of a normal-voltage continuous background activity and the appearance of an epileptiform EEG, defined as abundant epileptiform discharges, periodic/rhythmic discharges or electrographic seizure activity. Results: 134 patients were included, 65 had a good outcome. Early recovery of continuous background activity (within 24 h) occurred in 72 patients and predicted good outcome since 55 (76%) had good outcome, increasing the odds for a good outcome seven times compared to a late background recovery. Early appearance of an epileptiform EEG occurred in 38 patients and 34 (89%) had a poor outcome, increasing the odds for a poor outcome six times compared to a late debut. The time to background recovery and the time to epileptiform activity were highly associated with outcome and levels of neuron-specific enolase. Multiple regression analysis showed that both variables were independent predictors. Conclusions: Time to epileptiform activity and background recovery are independent prognostic indicators. Significance: Patients with early background recovery combined with late appearance of epileptiform activity may have a good outcome.

- BACKGROUND: The aim of this study was to describe out-of-hospital cardiac arrest (OHCA) survivors' ability to participate in activities of everyday life and society, including return to work. The specific aim was to evaluate potential effects of cognitive impairment. METHODS AND RESULTS: Two hundred eighty-seven OHCA survivors included in the TTM trial (Target Temperature Management) and 119 matched control patients with ST-segment-elevation myocardial infarction participated in a follow-up 180 days post-event that included assessments of participation, return to work, emotional problems, and cognitive impairment. On the Mayo-Portland Adaptability Inventory-4 Participation Index, OHCA survivors (n=270) reported more restricted participation In everyday life and in society (47% versus 30%; P<0.001) compared with ST-segment-elevation myocardial infarction controls (n=118). Furthermore, 27% (n=36) of pre-event working OHCA survivors (n=135) compared with 7% (n=3) of pre-event working ST-segment-elevation myocardial infarction controls (n=45) were on sick leave (odds ratio, 4.9; 95% confidence interval, 1.4-16.8; P=0.01). Among the OHCA survivors assumed to return to work (n=135), those with cognitive impairment (n=55) were 3x more likely (odds ratio, 3.3; 95% confidence interval, 1.2-9.3; P=0.02) to be on sick leave compared with those without cognitive impairment (n=40; 36%, n=20, versus 15%, n=6). For OHCA survivors, the variables that were found most predictive for a lower participation were depression, restricted mobility, memory impairment, novel problem-solving difficulties, fatigue, and slower processing speed. CONCLUSIONS: OHCA survivors reported a more restricted societal participation 6 months post-arrest, and their return to work was lower compared with ST-segment-elevation myocardial infarction controls. Cognitive impairment was significantly associated with lower participation, together with the closely related symptoms of fatigue, depression, and restricted mobility. These predictive variables may be used during follow-up to identify OHCA survivors at risk of a less successful recovery that may benefit from further support and rehabilitation.
