Heart disease often develops silently for years — and many people don’t realize they’re at risk until a major event happens. In this Part 2 episode, host Aaron Fournier sits down with Dr. Paul Harris to break down how cardiovascular disease really forms, why chronic low-grade inflammation is now considered a central driver (not just cholesterol), and what “stealth” heart disease looks like long before symptoms appear.

You’ll learn why 60–70% of heart attack patients can have normal cholesterol, how inflammation damages the endothelial lining of arteries, and why plaque instability — not just plaque presence — is what creates real danger. Dr. Harris explains the step-by-step process of plaque formation (including oxidized LDL, macrophages, and foam cells), how calcification can worsen the situation, and why nitric oxide regulation matters for blood flow, blood pressure, cognition, and overall vascular performance.

We also connect major hidden drivers that fuel cardiovascular inflammation, including:

• Oral health and cardiovascular risk (p. gingivalis)
  
  
• Gut permeability, LPS, and brain inflammation
  
  
• Oxidative stress and “oxidized LDL”
  
  
• Insulin resistance, belly fat, and metabolic inflammation
  
  
• Genetics like APOE variants and cardiovascular risk
  
  

Finally, Dr. Harris shares proactive testing options that can uncover risk earlier than standard cholesterol panels — including markers like hs-CRP, IL-6, homocysteine, ApoB-related markers, and imaging tools like calcium scoring and CCTA.

If you want to understand heart disease before it becomes an emergency — this episode lays out a clearer model for prevention, early detection, and smarter decision-making.
