About this trial
The purpose of this study is to gain a better understanding of the association between brain changes and cognitive deficits in coronary heart disease (CHD) patients undergoing coronary artery bypass grafting (CABG) and whether a low-cost thiamine intervention can be used to reduce post-CABG cognitive issues in CHD subjects.

Trial outcomes
Primary outcomes
Effects of thiamine treatment intervention on blood lactate levels.
Assess thiamine treatment effect on blood lactate levels in CABG patients with and without intervention measured via blood gas analyzer (ABL90 flex plus, Radiometer).
Effects of thiamine treatment intervention on blood thiamine levels.
Assess thiamine treatment effect on blood thiamine levels in CABG patients with and without intervention measured via blood gas analyzer (ABL90 flex plus, Radiometer).
Effects of thiamine treatment intervention on blood inflammatory levels.
Assess thiamine treatment effect on blood inflammatory levels in CABG patients with and without intervention measured via a custom kit, including cytokines from the human 38-plex magnetic cytokine/chemokine kit, will be used per manufacturer's instructions.
Evaluate cognitive function in CABG patients with thiamine treatment.
The investigators will evaluate cognitive function using the NIH Toolbox Cognition Battery (executive function, attention, and speed). CABG patients with thiamine treatment will show a change in cognition over CABG patients without thiamine treatment.
