Myocardial ischemia in an adolescent secondary to nutritional thiamine deficiency.

Thiamine (vitamin B1) is an essential vitamin found in most food products in developed nations. Deficiencies in this crucial vitamin lead to diseases related to nutritional needs, metabolic demands, enzymatic function, and neurological inflammation.
