Summary

This study looks at how sleep problems before heart surgery might impact recovery in 144 adults. Researchers will collect blood and stool samples before and after surgery to measure changes in metabolism, inflammation, and gut bacteria. The goal is to understand why poor sleep leads to worse outcomes, like confusion or longer hospital stays.
