Abstract

Diabetes is associated with a marked increased risk of atherosclerotic vascular disorders, including coronary, cerebrovascular, and peripheral artery disease. Cardiovascular disease (CVD) could account for disabilities and high mortality rates in patients with diabetes. Conventional risk factors, including hyperlipidemia, hypertension, smoking, obesity, lack of exercise, and a positive family history, contribute similarly to macrovascular complications in type 2 diabetic patients and non-diabetic subjects. The levels of these factors in diabetic patients are certainly increased, but not enough to explain the exaggerated risk for macrovascular complications in the diabetic population. Furthermore, recently, macrovascular complications of diabetes have been shown to start before the onset of diabetes. Indeed, several clinical studies have confirmed the increased risk of CVD in patients with impaired glucose tolerance (IGT). Since insulin resistance-related postprandial metabolic derangements are thought to play a central role in the development and progression of CVD in patients with IGT, amelioration of postprandial metabolic disturbance is a therapeutic target for the prevention of CVD in these high-risk patients. Therefore, in this paper, we review the molecular mechanisms for the increased risk of CVD in recent onset diabetes mellitus, especially focusing on postprandial dysmetabolism. We also discuss here the potential therapeutic strategies that specially target the mechanisms responsible for vascular alterations in diabetes.
