What this trial studies

This international, multicentre prospective cohort study aims to evaluate the relationship between the duration and magnitude of mean arterial pressure (MAP) outside of individual cerebral autoregulation limits and adverse neurological events in patients undergoing cardiac surgery. Utilizing non-invasive techniques such as near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD), the study will monitor blood pressure tailored to individual characteristics to potentially reduce complications. Additionally, it will explore biological associations between neurological outcomes, neurobiomarkers, and genetic factors to enhance understanding and improve patient safety and quality of life.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for elective primary or reoperative coronary artery bypass graft and/or valvular and/or ascending aorta surgery requiring cardiopulmonary bypass.

Not a fit: Patients undergoing urgent or emergency surgeries, or those requiring heart and/or lung transplantation, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved neurological outcomes and reduced incidence of postoperative complications for cardiac surgery patients.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in understanding the impact of cerebral autoregulation on neurological outcomes, suggesting potential for success.
