Insulin Resistance: The Driving Force Behind Cardiovascular Disease.  

Insulin resistance (IR) has emerged as a critical factor in the development and progression of cardiovascular disease (CVD). Insulin resistance initiates a series of physiological changes that significantly impact cardiovascular health:

1. Endothelial Dysfunction: IR impairs the function of blood vessel linings, promoting atherosclerosis. 1

2. Inflammation: Chronic low-grade inflammation, a hallmark of IR, accelerates plaque formation in arteries  3

3. Lipid Abnormalities: IR leads to dyslipidemia, characterized by high triglycerides and low HDL cholesterol 1 3

4. Hypertension: Insulin's role in blood pressure regulation is disrupted, contributing to hypertension 3

5. Hyperglycemia: Elevated blood sugar levels damage blood vessels and nerves controlling the heart 1  Warning; You can have high Insulin levels without having high blood sugar - make sure you get Insulin levels tested. (Ask us how) 

   
   
   
   

Evidence Supporting IR as a CVD Driver

Multiple studies have demonstrated the central role of insulin resistance in cardiovascular disease:

1. The Insulin Resistance Atherosclerosis Study showed a strong relationship between IR and CVD in a large multiethnic cohort, independent of other risk factors. 4

2. In the San Antonio Heart Study, IR was significantly associated with increased risk of CV outcomes in individuals without diabetes. 4

3. A meta-analysis by Gast et al. confirmed that IR is a strong predictor of atherosclerotic cardiovascular disease. 4

Improving Cardiovascular Health by Targeting Insulin Resistance

Reducing insulin resistance has been shown to improve cardiovascular risk markers and overall health:

1. Lifestyle Interventions: A study published in the Journal of the American Heart Association demonstrated that improving insulin sensitivity through lifestyle changes resulted in:

   • Reduced blood pressure

   • Improved lipid profiles

   • Decreased inflammation markers

   • Enhanced endothelial function 5

Strategies to Reduce Insulin Resistance

Evidence-based approaches to improve insulin sensitivity include:

1. Regular Movement: 3 days a week 20min of Resistance training. Do something that works your muscles from 5-20 repetitions. 

2. Healthy Diet: A diet without processed foods(sugar/fructose/processed grains/seed oils). Focus on eating Protein foods which make you feel full (satiety)  and adding Salads and a little low sugar fruit. 

3. Weight Management: Losing excess weight, particularly abdominal fat, significantly improves insulin sensitivity.

4. Stress Reduction: Chronic stress contributes to IR, making stress management crucial.

5. Adequate Sleep: Poor sleep quality is linked to IR, emphasizing the importance of good sleep hygiene. Asleep by latest 10pm, get 7hrs 30min per night.

Conclusion

Insulin resistance is not merely a precursor to diabetes but a direct driver of cardiovascular disease.

By understanding this connection, you can take charge of your health and improve overall health and wellbeing.
