Brief Summary

This study aims to explore the association between perioperative homocysteine (Hcy) levels and their pre-to-postoperative changes with postoperative complications and all-cause mortality in elderly patients undergoing non-cardiac surgery. Besides, the dynamic changes in Hcy levels may reflect metabolic shifts, highlighting their potential value in predicting adverse postoperative outcomes. These findings suggest that monitoring perioperative Hcy levels and their changes could help identify high-risk patients and inform postoperative management strategies.
