This episode is brought to you by The Primal Skincare.

Vascular surgeon Dr. Lily Johnston breaks down the definitive science of heart attack prevention and evaluates how modern diet and lifestyle choices directly accelerate or mitigate your cardiovascular risk. We explore the complex biological mechanisms underlying plaque formation and arterial rupture, moving beyond outdated dogmas to examine the real drivers of vascular disease: chronic inflammation, metabolic dysfunction, and the direct effects of insulin and glucose on your endothelial lining.

Whether you are navigating the nuances of cholesterol management or looking for the most accurate diagnostic testing, this episode provides an authoritative, evidence-based roadmap to optimize your heart health and protect your arteries.

In This Episode, We Reveal:

• The Pathophysiology of Plaque: How arterial plaque forms, why it ruptures, and the crucial clinical distinction between volatile soft plaque and stable calcified plaque.
• The Metabolic Drivers: The profound impact of chronic glucose and insulin elevation on arterial degradation.
• Advanced Diagnostics: Why standard lipid panels fail to show the whole picture, and how advanced imaging tools can detect early-stage disease.
• The Cholesterol Matrix: A scientific contextualization of LDL, the complexities of HDL, and whether elevated markers are a true risk factor on low-carbohydrate diets.
• Dietary Realities: A medical critique of common foods, the cardiovascular impact of processed ingredients, and the evidence supporting the Mediterranean diet.
