Metabolic abnormalities: triglyceride and low-density lipoprotein.
Increased plasma triglyceride and reduced high-density lipoprotein cholesterol are key features of the metabolic syndrome. Although elevated low-density lipoprotein cholesterol is not an integral characteristic of this syndrome, there is commonly an increase in the proportion of small, dense low-density lipoprotein particles. Together, these abnormalities constitute the atherogenic dyslipidemia of the metabolic syndrome. This article reviews the pathophysiology of altered triglyceride and low-density lipoprotein metabolism in the metabolic syndrome, outlines the relationship of these lipoprotein abnormalities to increased risk of coronary heart disease,and highlights the application of this information to clinical practice. The role of reduced high-density lipoprotein in the metabolic syndrome is discussed elsewhere in this issue.
