The triglyceride controversy: a review of the data

Area of Science:

• Cardiology
• Metabolic Syndrome
• Atherosclerosis Research

Background:

• The role of elevated triglyceride levels in coronary heart disease (CHD) and atherosclerosis remains controversial.
• Epidemiologic studies suggest an association, but often fail to account for confounding variables like high-density lipoproteins.
• Current statistical methods for analyzing triglyceride data have limitations, contributing to the lack of consensus.

Purpose of the Study:

• To critically evaluate the existing evidence on the significance of hypertriglyceridemia in atherosclerosis and CHD.
• To address the controversies and limitations in current research regarding triglyceride levels and cardiovascular risk.
• To explore the relationship between hypertriglyceridemia, apolipoprotein B, and coronary atherosclerosis.

Main Methods:

• Review and analysis of existing epidemiologic case-control studies on triglyceride levels and CHD.
• Examination of statistical approaches used in analyzing triglyceride data.
• Consideration of associations between hypertriglyceridemia and apolipoprotein B concentrations.

Main Results:

• While some studies link elevated triglycerides to CHD, their independent risk factor status is debated due to confounding variables.
• A significant association exists between hypertriglyceridemia and high concentrations of apolipoprotein B.
• Apolipoprotein B is suggested by some researchers to be a superior predictor of coronary atherosclerosis compared to traditional lipid markers.

Conclusions:

• Despite ongoing debate and methodological challenges, elevated triglyceride levels warrant serious consideration in the context of cardiovascular risk assessment.
• Hypertriglyceridemia may be linked to atherosclerosis through mechanisms involving apolipoprotein B.
• Further research with robust statistical methods is necessary to definitively establish the role of triglycerides in CHD.
