[en] Rationale: Cardiac arrest (CA) is a serious condition characterized by high
mortality rates, even after initial successful resuscitation, mainly due to neurological
damage. Whether brain-heart communication is associated with
outcome after CA is unknown. Heartbeat-evoked brain potentials (HEPs) represent
neurophysiological indicators of brain-heart communication, as they
reflect cortical representation of interoceptive signal processing. The aim of
this study was to address the association between HEPs and survival after
CA.
Methods: HEPs were calculated from resting EEG/ECG in 55 CA patients
24 h after resuscitation. All patients were treated with targeted temperature
management and a standardized sedation protocol during assessment. We
investigated the association between HEP amplitude (180{320 ms, 455{595
ms, 860{1000 ms) and 6-month survival. Results: Twenty-five of 55 patients
(45%) were still alive at 6-month follow-up. Survivors showed a higher
HEP amplitude at frontopolar and frontal electrodes in the late HEP interval
than non-survivors. This effect remained significant after controlling for
between-group differences in terms of age, Fentanyl dose, and time lag between
resuscitation and EEG assessment. There were no group differences in
heart rate or heart rate variability.
Conclusion: Brain-heart communication, as reflected by HEPs, is associated
with survival after CA. Cardiovascular autonomic arousal may not be involved
in mediating this e ect. Adequate cortical representation of interoceptive
signals may be essential to preserve cariovascular health and should be in the
focus of prevention strategies. Future studies should address the brain-heart
axis in CA.
