Area of Science:

  • Metabolic Syndrome and Cardiovascular Health
  • Endocrinology and Vascular Biology

Context:

  • The modern Western lifestyle is a significant factor in the prevalence of insulin resistance.
  • Genetic predisposition plays a crucial role in developing insulin resistance and hyperinsulinism.

Purpose:

  • To review the multifaceted dysfunctions associated with insulin resistance and hyperinsulinism (Syndrome X).
  • To explore the mechanisms linking these dysfunctions to atherogenesis.
  • To discuss therapeutic strategies for managing insulin resistance and reducing cardiovascular risk.

Summary:

  • Insulin resistance necessitates higher insulin levels, leading to hyperinsulinism.
  • This condition affects multiple tissues and systems, contributing to Syndrome X.
  • Dysfunctions in blood pressure, endothelium, lipid metabolism, and fibrinolysis, alongside hyperinsulinism, promote atherosclerosis.

Impact:

  • Highlights the complex interplay between lifestyle, genetics, and metabolic dysfunction in cardiovascular disease.
  • Provides a comprehensive overview of Syndrome X and its atherogenic pathways.
  • Informs therapeutic approaches to mitigate insulin resistance and its associated morbidity and mortality.
