Summary

This study aimed to see if taking omega-3 supplements before and after major heart surgery could lower the chance of confusion (delirium) in patients aged 65 and older. The trial was planned for many participants but was stopped early after enrolling only one person. Because it ended so soon, we cannot draw any meaningful conclusions about whether omega-3s help.
