Summary

This study looked at over 2,400 adults who had open-heart surgery to find out how many still have pain three months later and what makes it more likely. Researchers measured pain levels and medication use right after surgery and checked back at three months. The goal is to better understand and eventually prevent chronic pain after heart surgery.
