Summary

Elevated serum triglyceride levels are an independent risk factor for cardiovascular disease, especially in women. Hypertriglyceridemia contributes to atherosclerosis through atherogenic lipoproteins and associated metabolic changes.

Area of Science:

  • Cardiovascular Medicine
  • Lipid Metabolism
  • Epidemiology

Context:

  • Elevated serum triglyceride is consistently identified as a significant risk factor in univariate analyses.
  • Recent studies indicate triglyceride and VLDL levels are key discriminators for coronary artery disease.
  • Angiographic data links elevated triglyceride, VLDL, and IDL to coronary artery disease severity.

Purpose:

  • To evaluate the independent role of serum triglyceride levels in cardiovascular disease risk.
  • To explore the variable impact of different hypertriglyceridemia types on cardiovascular risk.
  • To elucidate the atherogenic mechanisms associated with elevated triglycerides.

Summary:

  • While multivariate analyses sometimes obscure its significance, meta-analyses and prospective studies support triglycerides as an independent risk factor, particularly in women.
  • Hypertriglyceridemia's cardiovascular risk varies; familial forms show moderate impact, while combined hypertriglyceridemia and hyperapobetalipoproteinemia significantly increase premature cardiovascular disease risk.
  • Atherogenesis is promoted by cholesterol ester-rich small VLDL and remnant accumulation, alongside associated factors like lower HDL cholesterol, oxidized LDL, hemostasis disorders, and insulin resistance.

Impact:

  • Confirms hypertriglyceridemia as an independent cardiovascular risk factor, guiding clinical risk assessment.
  • Highlights the heterogeneous nature of hypertriglyceridemia and its differential impact on cardiovascular disease.
  • Provides insights into the atherogenic potential of specific lipoprotein particles and associated metabolic disturbances.
