Insulin resistance and atherosclerosis

Area of Science:

• Metabolic disorders
• Cardiovascular science
• Pathophysiology

Background:

• Insulin resistance is a complex metabolic defect influenced by genetics and pathophysiology.
• Associated conditions include atherogenic dyslipidemia, hyperinsulinemia, dysglycemia, obesity-related inflammation, and ectopic steatosis.
• These factors promote endothelial dysfunction and atherosclerosis development.

Purpose of the Study:

• To highlight the multifaceted nature of insulin resistance.
• To underscore the limitations of current risk factor management in preventing residual cardiovascular risk.
• To emphasize the need for novel interventions targeting the metabolic and vascular milieu.

Main Methods:

• This study is a review of current literature on insulin resistance and atherosclerosis.
• It synthesizes information on the contributing factors and their pathophysiological mechanisms.
• It discusses the inadequacy of current treatments in addressing residual risk.

Main Results:

• Insulin resistance is linked to atherogenic dyslipidemia, hyperinsulinemia, dysglycemia, inflammation, and ectopic steatosis.
• These conditions collectively lead to endothelial dysfunction and atherosclerosis.
• Current risk factor management strategies do not fully mitigate residual cardiovascular risk.

Conclusions:

• Novel therapeutic strategies are required to fundamentally alter the metabolic and vascular environment.
• Interventions should aim to slow the progression of atherosclerosis.
• Altering the metabolic and vascular milieu holds promise for improving patient outcomes.
