Investigating brain-heart interactions after cardiac arrest

Brain Heart InterActioNs in Cardiac Arrest. Ancillary Study of the HEAVENwARd Trial

Observational CMC Ambroise Paré · NCT06327334

This study is trying to understand how the brain and heart work together in patients who have survived cardiac arrest to see if it can help predict their recovery.

What this trial studies

This study aims to explore the brain-heart interactions in patients who have experienced cardiac arrest and have been resuscitated. It is an ancillary study to the HEAVENwARd trial, focusing on identifying new prognostic markers that can predict outcomes for patients with hypoxic-ischemic brain injury. The study will include patients admitted to intensive care units who have undergone EEG monitoring as part of their routine care. By analyzing these interactions, the researchers hope to improve prognostic evaluations for patients recovering from cardiac arrest.

Who should consider this trial

Good fit: Ideal candidates are patients admitted to the ICU after resuscitation from cardiac arrest who are in a coma and require sedation and targeted temperature management.

Not a fit: Patients who are dying or have limitations on life support before EEG monitoring may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better prognostic tools for predicting outcomes in cardiac arrest survivors.

How similar studies have performed: Other studies have shown promise in understanding brain-heart interactions, but this specific approach is relatively novel.
