Once diagnosed with diabetes mellitus, the risk of diseases, such as nephropathy, neuropathy, retinopathy and heart disease also increases. The complication of diabetes accompanying myocardial disorder is known as diabetic cardiomyopathy, which is characterized by ventricular dilation that is usually asymptomatic as diabetes progresses. Myocardial fibrosis is closely related to diastolic dysfunction. Thiamine (vitamin B1), an essential micronutrient, has been reported to attenuate diabetic complications and all diabetics may be lacking in thiamine. Thiamine is a coenzyme utilized at multiple steps of glucose metabolism. We believe that thiamine repletion under hyperglycemia might activate glucose oxidation and reduce the overflow of glucose to the hexosamine biosynthesis pathway of glucose metabolism with concomitant reduction of diabetic lesions. The aim of this article is to highlig.. View More»
