ClinConnect Summary

This clinical trial is studying how to better identify patients at risk for cognitive problems and delirium after heart surgery. Researchers want to use advanced brain imaging (called MRI) to find signs of small blood vessel disease in the brain, which can lead to confusion and memory issues in older patients. They are also looking for specific biomarkers, which are biological signs that can indicate a higher risk of these problems, to help identify patients who might experience cognitive difficulties after their surgery.

To participate in this trial, you need to be between 50 and 85 years old and scheduled for elective heart surgery. You will also need to give written consent before the surgery. However, individuals with certain mental health issues, other diseases that can cause memory problems (like Alzheimer’s), or severe cancers will not be eligible. If you join the study, you can expect to undergo MRI scans and other assessments to help researchers understand more about how to prevent or manage cognitive issues after surgery. This research could ultimately lead to better care for patients undergoing heart surgery.
