title: The atherosclerotic process and its exacerbation by diabetes.
abstract: The excess of glucose appears to play an important and specific role in the genesis of macroangiopathy in diabetics. Activation of protein kinase-C, the sorbitol pathway, and AGE formation are thought to be the major pathways linking the degree of glycaemic compensation with the pathogenetic process of macrovascular disease. HSPG is likely to be a key element in this process since it is a regulator of endothelial permeability, vascular antithrombotic capacity, insulin sensitivity (with respect to lipoprotein lipase availability), and vascular extracellular matrix content and smooth-muscle-cell activation. Loss of HSPG is suggested clinically by the presence of microalbuminuria, to the development of which diabetic control also contributes significantly. However, genetic factors also seem to be involved. Much more insight into the precise mechanismus is necessary to unravel the cellular and molecular chains of events for the premature and accelerated atherosclerosis in diabetic patients.
