Thiamine Intervention and Cognition in Older Adults Undergoing Coronary Artery Bypass Grafting - A Randomized Clinical 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.

Inclusion: Patients with Coronary Heart Disease (CHD) scheduled for Bypass Grafting (CABG); Thiamine deficiency before CABG; European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) >1.5%; Off-pump surgery.

Exclusion: Dementia at baseline [Montreal Cognitive Assessment (MoCA) <21 within 5 days before CABG]; Known thiamine allergy; Unable to give consent due to illness; History of hyperlactatemia; Recent (within several years and/or up to the judgment of the PI/co-PIs) cerebral incidents (seizure or head trauma resulting in loss of consciousness and/or concussion); Stroke; Diagnosed psychiatric diseases (clinical depression, schizophrenia, manic-depression); Patients with history of alcohol or substance abuse; Acute or chronic infections (tuberculosis, hepatitis, or encephalopathy); Diagnosed neuro-degenerative diseases (Alzheimer's or Parkinson's disease); Chronic immunodeficiency (including HIV); Uncontrolled blood glucose levels; Current in-take of thiamine; Congenital brain deficits will also be excluded.
