Predicting brain complications after heart surgery

Official title: Predicting Cerebrovascular Adverse Events Post Cardiac Surgery With Cardiopulmonary Bypass by Means of Cerebral AutoreguLation Indices

Run by IRCCS Policlinico S. Donato · NCT05786274 · Data updated 2026-11-12

This study is testing two ways to measure how well the brain controls blood flow during heart surgery to see if it can help predict the risk of complications like strokes afterward.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old who are undergoing cardiac surgery and have a normal sinus rhythm.

Probably not a fit

Patients under 18 years old, those with autonomic disorders, or those requiring carotid interventions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate how well the brain regulates blood flow during different phases of cardiac surgery that involves cardiopulmonary bypass. It will compare two methods of measuring cerebral autoregulation: one using a transcranial Doppler device to assess blood flow velocity and another using near infrared spectroscopy. The ultimate goal is to develop a predictive model for postoperative cerebrovascular outcomes, such as strokes, based on the data collected during the surgery.

Why it matters

Potential benefit: If successful, this study could help identify patients at risk for cerebrovascular events after cardiac surgery, allowing for better preventive measures.

How similar studies have gone: While similar studies have explored cerebral autoregulation in cardiac surgery, this specific predictive modeling approach is relatively novel.
