Summary

This study looked at 49 adults aged 30-65 who had a first heart attack about 4 months earlier. Researchers used brain scans to see if changes in the brain's blood vessels or structure are linked to memory or thinking problems. The goal is to better understand these issues and help with early detection and prevention of dementia related to heart disease.
