Atherogenicity of postprandial hyperglycemia and lipotoxicity

Research output: Contribution to journalArticlepeer-review

Abstract

Type 2 diabetes is characterized by a gradual decline in insulin secretion in response to nutrient loads; hence, it is primarily a disorder of postprandial glucose regulation. However, physicians continue to rely on fasting plasma glucose and glycated hemoglobin to guide management. There is a linear relationship between the risk of cardiovascular death and the 2-h oral glucose tolerance test, while a study confirms postprandial hyperglycemia as independent risk factor for cardiovascular disease in type 2 diabetes. At the same time, several studies show that postprandial hypertriglyceridemia may also be a cardiovascular risk factor. Interestingly, the simultaneous presence of postprandial hyperglycemia and postprandial hypertriglyceridemia has an additive effect in worsening endothelial function and inflammation. Evidence supports the hypothesis glucose postprandial hyperglycemia and hypertriglyceridemia may favor the appearance of the cardiovascular disease through the generation of an oxidative stress. Furthermore, clinical data suggest that postprandial hyperglycemia is a common phenomenon even in patients who may be considered in “good metabolic control”. Therefore, physicians should consider monitoring and targeting postprandial plasma glucose, as well as glycated hemoglobin and fasting plasma glucose, in patients with type 2 diabetes.
