Rethinking Heart Disease: It’s Not Just About Blocked Arteries Anymore
For years, coronary artery disease (CAD) was treated like a plumbing problem—blocked arteries leading to heart attacks. We were taught to manage cholesterol and use stress tests or imaging to look for obstructive plaques.
But we now know that most heart attacks don’t come from big blockages. They come from small, unstable plaques that rupture and cause sudden clots. And those plaques often don’t show up on traditional tests.
Instead, they form silently over time—driven by inflammation, oxidative stress, immune dysfunction, and poor metabolic health.
Inflammation Is the Real Villain
Your arteries aren’t just tubes—they’re living tissue. The inner lining (called the endothelium) helps regulate blood flow, inflammation, and repair. When your body is under constant stress—blood sugar swings, toxins, poor sleep, processed food, and emotional strain—the endothelium starts to break down.
That damage is where plaque begins.
Why Cholesterol Isn’t the Whole Story
Plenty of people with “normal” cholesterol still suffer heart attacks. That’s because basic labs like LDL and total cholesterol miss the deeper story.
Ask for advanced testing and imaging to detect risk before symptoms show up.
Key Markers:
- Lp(a): A genetic risk factor linked to plaque
- ApoB & LDL-P: Show how many atherogenic particles are circulating
- Oxidized LDL & hs-CRP: Inflammation and oxidative stress indicators
- Myeloperoxidase (MPO) & Lp-PLA2: Reveal vulnerable, rupture-prone plaque
- Coronary Calcium Score & CIMT( if indicated and available): Catch silent plaque before it strikes
Real Prevention Starts With Protecting the Endothelium
In our integrative practice, we move beyond just lowering LDL. Our focus is to restore arterial health and reverse the root causes of endothelial damage.
Here’s some options:
1. Reduce Oxidative Stress
- CoQ10: Essential for heart cell energy and mitochondrial support
- Astaxanthin & Vitamin C/E: Target free radicals damaging arterial walls
2. Boost Nitric Oxide (NO) for Blood Flow
- Beetroot, Arugula, and Citrulline: Naturally increase NO
- Dark Cocoa Flavanols: Improve vascular flexibility and tone
3. Support the Glycocalyx – Your Arterial Shield
The glycocalyx is a protective gel-like layer inside your arteries—think of it as your vascular armor. It regulates inflammation, prevents plaque, and keeps your arteries smooth.
Consider:
- Rhamnan sulfate – Supports structural integrity
- Sulforaphane (from broccoli sprouts) – Activates antioxidant defense systems
- Polyphenols (like EGCG, quercetin) – Improve endothelial signaling
- Vitamin K2 (MK-7) – Helps prevent arterial calcification and supports vascular elasticity
4. Lower Inflammation and Improve Stability
- Omega-3s: Lower inflammation and reduce risk of plaque rupture
- Curcumin & Resveratrol: Regulate inflammatory gene pathways (like NF-κB)
5. Fix the Metabolic Terrain
- Berberine, Magnesium, Alpha-lipoic acid: Improve insulin sensitivity and reduce endothelial stress
- Time-Restricted Eating & Fasting-Mimicking Diets: Support autophagy, mitochondrial health, and repair
Don’t Wait for a Crisis to Change Your Heart Health
Most heart attacks are preventable—but only if we look in the right places.
At my practice, we combine internal medicine with functional testing and longevity science to give you a clear, personalized view of your heart health—before disease shows up on imaging or labs.
If you’re tired of being told “everything looks normal” when you know something isn’t right, it may be time to go deeper.
The next decade of your life depends on what you do today.
Let’s protect your heart, your brain, and your future—starting now.
