Let me say what every mainstream cardiologist refuses to say out loud:

There is plastic in your arteries. There is plastic in your brain. There is plastic in your heart. And your body has no way to get rid of it.

That’s not fearmongering. That’s peer-reviewed science, published in The New England Journal of Medicine, Nature Medicine, and journals your cardiologist will never mention at your next appointment.

For decades, conventional medicine has told you to “just take a statin” and stop worrying about root causes. I’ve been shouting from the rooftops for over two decades that the real drivers of heart disease are inflammation, oxidative stress, and environmental toxicity — not your cholesterol number. Now the research is finally catching up.

And a new therapy called Therapeutic Plasma Exchange (TPE) is being studied as one of the only known ways to physically pull microplastics back out of the human body.

Let’s get into it.

What Is Therapeutic Plasma Exchange (TPE)?

Therapeutic Plasma Exchange — sometimes called therapeutic apheresis — is a medical procedure where your blood is drawn out, separated into its components, and the plasma (the liquid portion that carries everything dissolved in your blood) is either filtered or replaced entirely. Your red blood cells, white blood cells, and platelets are then returned to your body along with a replacement fluid (usually albumin or fresh plasma).

Think of it like a dialysis-style car wash for your blood.

TPE is not new or experimental. It has been FDA-cleared for decades and used routinely for autoimmune diseases like myasthenia gravis, Guillain-Barré syndrome, and certain blood disorders. What is new is the application: using TPE to remove environmental pollutants like microplastics, nanoplastics, PFAS (“forever chemicals”), and inflammatory molecules that your liver and kidneys simply cannot excrete on their own.

A typical session takes 2 to 4 hours. You’re awake the whole time. Most patients describe it as relaxing.

Why Can’t Your Body Just Get Rid of Plastic?

Here’s the brutal truth: your liver, kidneys, and gut were not designed to handle synthetic polymers.

Your body evolved over millions of years to detoxify naturally occurring compounds — heavy metals, plant alkaloids, bacterial endotoxins, metabolic waste. It uses elegant pathways like glutathione conjugation, methylation, sulfation, and biliary excretion to clear these.

But plastic? Plastic didn’t exist on this planet until about 100 years ago.

Polyethylene, polystyrene, polypropylene, PET, PVC — these are man-made polymers with chemical bonds so stable that they resist biological degradation for decades to centuries. When microplastic particles enter your bloodstream through the food you eat, the water you drink, or the air you breathe, here’s what happens:

1. The smallest particles (nanoplastics) slip across protective barriers — including the gut wall, the blood-brain barrier, and the placenta. Yes, they reach your unborn child.
2. Larger particles get engulfed by immune cells (macrophages) that try to digest them and fail. The plastic stays trapped inside the cell, triggering chronic low-grade inflammation.
3. Fat-soluble plastics accumulate in fatty tissues — including arterial plaque, the brain (which is ~60% fat), the liver, and the testicles.

Once plastic is lodged in tissue, there is no known biological pathway to break it down. It just sits there. For years. Leaching chemicals. Driving inflammation. Quietly poisoning you.

Researchers at the University of New Mexico recently found that microplastic concentrations in human brain tissue have risen measurably in just the last eight years — and the highest levels were found in patients who had died with dementia. Let that sink in.

Why This Matters For Your Heart

This is where it gets personal for me as a cardiologist.

In 2024, a landmark study in the New England Journal of Medicine examined plaque removed from the carotid arteries of patients undergoing surgery. The researchers found microplastics and nanoplastics embedded in the atherosclerotic plaque of nearly 60% of patients.

Here’s the kicker: patients with plastics in their plaque were 4.5 times more likely to suffer a heart attack, stroke, or death within the next three years compared to patients whose plaque was plastic-free.

Four-and-a-half times. That’s not a subtle signal. That’s a catastrophe.

Follow-up research has only deepened the concern:

• Microplastics drive oxidative stress and mitochondrial dysfunction in vascular cells.
• They accelerate atherosclerosis — the artery-clogging disease that underlies most heart attacks and strokes.
• They trigger endothelial dysfunction, which is the earliest known step in cardiovascular disease.
• They disrupt lipid metabolism and promote clotting.
• Animal studies show they directly worsen plaque buildup even without changes to diet or cholesterol.

This is why I tell every patient who walks into my practice: if you want a 100 Year Heart, you cannot ignore the plastic problem. It is as important as what you eat, how you sleep, and how you move.

How Does TPE Actually Pull Microplastics Out?

In May 2025, a team led by researchers at University Hospital Dresden published the first evidence in the journal Brain Medicine that therapeutic apheresis can physically remove microplastic- and nanoplastic-like particles from human beings. They analyzed the filtrate (the waste fluid captured during apheresis) and detected signatures consistent with polyethylene, polystyrene, and other common plastics.

The mechanism is elegant in its simplicity:

1. Blood is drawn from a vein in one arm.
2. A centrifuge or filter separates plasma from blood cells. Plasma is the liquid that carries microplastics, toxins, inflammatory proteins, and autoantibodies.
3. The “dirty” plasma is either discarded (and replaced with clean albumin) or passed through specialized filters that trap particles based on size and charge.
4. Your blood cells are returned to you along with the replacement fluid.

The result: a measurable reduction in circulating microplastics, inflammatory cytokines, and other unwanted compounds in a single session.

Several clinical programs — most notably Circulate Health in the United States and Clarify Clinics in London — are now offering TPE specifically for longevity, with early data suggesting reductions in biological age markers of around 2.6 years after a full treatment protocol.

Is It Safe? What Are the Risks?

TPE has been performed hundreds of thousands of times over several decades, and its safety profile is well established. That said, no medical procedure is risk-free. Potential risks include:

• Temporary drops in blood pressure or dizziness during the procedure
• Tingling or muscle cramps from the citrate anticoagulant used to keep the blood flowing
• Mild allergic reactions to the replacement fluid
• Rare infections at the IV site
• Temporary depletion of clotting factors and immunoglobulins (which is why pre- and post-treatment labs matter)

The procedure should only be performed by trained medical professionals in a clinical setting with proper monitoring. It is not appropriate for everyone — pregnant women, patients on certain medications, and people with active infections need careful evaluation first.

Cost is another real-world factor. Sessions range from several thousand dollars to over $12,000 each in premium longevity clinics, and most insurance won’t cover TPE for environmental detoxification (only for FDA-approved conditions like autoimmune disease).

Where TPE Fits in the 100 Year Heart Method

Regular readers know I built the 100 Year Heart Method™ around six pillars: Eat Well, Live Well, Think Well, Test Don’t Guess, Evidence-Based Supplements, and BioHacking Strategies.

TPE is a BioHacking Strategy — and it’s a powerful one. But it’s not a replacement for the foundations. It’s a tool for people who have already cleaned up their life and want to go deeper.

Here’s what you do first, before you ever consider TPE:

• Eat Well. Wild seafood, pasture-raised meats, organic produce, filtered water. Stop drinking out of plastic bottles. Stop microwaving food in plastic containers. Throw out your plastic cutting boards.
• Live Well. Get sunlight. Move your body. Sleep deeply. Avoid synthetic fabrics against your skin when you can.
• Test Don’t Guess. Get comprehensive labs to measure your inflammation, oxidative stress, heavy metals, and cardiovascular risk markers. You cannot fix what you do not measure.
• Support your natural detox pathways with sauna use, adequate hydration, high-fiber foods, quality sleep, and targeted nutrients like sulforaphane, glutathione, and N-acetylcysteine.

Once you’ve built that foundation, TPE becomes a strategic accelerant — a way to reduce the toxic load your body has been carrying, potentially for decades.

Big Investment: This procedure starts at $7500 per session.

The Bottom Line

You cannot live a modern life and avoid microplastics completely. They are in the air, the water, the food, the soil, and — as the research now confirms — in your blood, your brain, and your arteries.

Your body cannot remove them on its own. Mainstream cardiology has no answer for this. Most doctors don’t even acknowledge the problem exists.

Therapeutic Plasma Exchange is one of the first real, measurable tools we have to physically pull these synthetic toxins back out. The research is early, the costs are high, and it is not a silver bullet. But for the right patient — someone who has already done the foundational work and wants to take the next step toward a 100 Year Heart — TPE deserves a serious look.

As always: test, don’t guess. Work with a practitioner who understands root-cause cardiology. Build the foundation first. Then consider the advanced tools.

Your heart was built to beat for a century. Let’s give it every chance to do so.
