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.

Disqualifiers

Dementia at baseline [Montreal Cognitive Assessment (MoCA) <21 within 5 days before CABG]

Current in-take of thiamine

Known thiamine allergy

Uncontrolled blood glucose levels

Trial outcomes

Primary outcomes

1

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).

Time frame
Baseline and after 1 month after CABG.
2

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).

Time frame
Baseline and after 1 month after CABG.
3

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.

Time frame
Baseline and after 1 month after CABG.
4

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.

Time frame
Baseline and after 1 month after CABG.
