Official title Thiamine Intervention and Coronary Artery Bypass Grafting
ClinicalTrials.gov ID: NCT06326996
What this study is testing

- What it's testing
- The study aims to learn how brain changes relate to memory problems in patients with coronary heart disease who have heart‑bypass surgery, and to see if thiamine can help lower those problems.
- Who it's for
- Adults with coronary heart disease who are scheduled to have coronary artery bypass grafting.
- What's involved
- Participants will receive either thiamine or a placebo, and will have brain and memory tests before and after surgery, along with routine follow‑up visits.
- Phase 1: an early, usually small safety study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
