The Vascular Asset Report

A standard lipid panel measures cholesterol concentrations in the blood. It doesn't, however, measure the condition of the blood vessels. So a patient can hit every target on his panel and still have disease brewing in his arterial walls because those walls were never actually examined.

This report looks at a structure that conventional medicine almost never assesses: the endothelial glycocalyx. It's a microscopic layer lining every blood vessel in the human body. When it degrades, the cascade toward vascular disease begins. When it stays intact, the vessels remain protected. Most physicians don't test for it.

For executives experiencing mental fog, declining energy, or erectile dysfunction, these symptoms often get attributed to stress and aging. But they can also be the earliest signals of a vascular problem: nitric oxide production falling below the threshold needed for normal organ function.

The path forward requires different testing, followed by targeted restoration.

He works out three times a week. He eats reasonably well. No chest pain, no shortness of breath. His lipid panel comes back within normal range: LDL at 92, HDL at 54, triglycerides at 118. His doctor tells him "everything looks normal". No further testing needed.

Background

In 2023, researchers published a collaborative analysis in The Lancet examining over 31,000 patients on statin therapy. These were patients who had achieved their target cholesterol levels. They took their medications. They followed the protocol. By every standard measure, they looked protected.

A substantial proportion of major cardiovascular events occurred anyway.

The study found something worth noting. In patients whose LDL was controlled, inflammation (measured by hs-CRP) predicted future events more reliably than cholesterol did. The patients were hitting their lipid targets, but something else was still wrong.

The math is sobering. Statins reduce cardiovascular risk by roughly 25 to 35 percent. That leaves 65 to 75 percent of baseline risk unaddressed.¹ For the patient who thinks his lipid panel represents a complete picture of his vascular health, that residual risk stays invisible. It's never measured. It's never discussed.

A lipid panel measures what's floating in the bloodstream. It tells you nothing about the blood vessels themselves. The numbers capture one variable. They miss the one that also matters: the state of the vessel wall.

The glycocalyx is a gel-like layer that extends from the surface of the endothelium into the bloodstream. It's made of complex sugar-protein molecules that form a protective mesh. In healthy vessels, this layer measures between 0.5 and 5 micrometers thick, thinner than a strand of human hair. But despite its size, the cumulative surface area across the entire vascular tree is enormous—roughly 3,000 square meters, about six tennis courts worth of tissue that most physicians never evaluate.

What It Does

This structure acts as a selective barrier, controlling what can pass through the vessel wall. It senses blood flow and triggers nitric oxide production, which keeps vessels relaxed and open. And it prevents immune cells from sticking to the vessel wall and triggering inflammation.

When the glycocalyx degrades, these functions break down. LDL particles that would normally be deflected now pass through the vessel wall and nitric oxide production drops. Inflammatory cells then stick to the exposed endothelium and start the cascade that leads to plaque formation.

The Timing

A 2018 study by Machin et al. examined glycocalyx degradation across different age groups.² The findings showed that measurable thinning of this layer occurs years before atherosclerosis becomes detectable by imaging or biomarker testing. Older adults in the study had 33% lower glycocalyx thickness compared to younger participants.

The sequence runs in a specific order: glycocalyx degrades first, endothelial dysfunction follows, and structural arterial disease develops last. The initiating event happens years before calcified plaque ever shows up on a coronary calcium scan.

He gets a prescription for a PDE-5 inhibitor and advice to consider reducing his workload. This presentation is common. The framing is incomplete.

What this patient may actually be experiencing is a vascular problem: systemic perfusion failure. This is what happens when nitric oxide production falls below the level needed to maintain adequate blood flow to high-demand organs.

The Mechanism

Nitric oxide is the body's primary vasodilator. It's produced by endothelial cells in response to shear stress detected by the glycocalyx. When released, it relaxes the vessel wall and widens the artery, increasing blood flow. When nitric oxide production declines, vessels constrict, flow decreases, and organs receive less oxygen and fewer nutrients than they need.

The brain and the sexual organs are particularly sensitive to this. They have high metabolic demands and little tolerance for reduced blood flow. When nitric oxide availability falls, these organs show symptoms first.

The Evidence

A 2011 meta-analysis in the Journal of the American College of Cardiology examined data from 12 studies with over 36,000 participants. Men with erectile dysfunction had a 48% higher risk of cardiovascular disease compared to men without ED.⁵ A separate meta-analysis confirmed that ED independently predicts cardiovascular events and mortality.

The same nitric oxide deficiency that impairs neurovascular coupling in the brain also impairs erections. These symptoms look unrelated on the surface but share a common origin.

Erectile dysfunction functions as a vascular biomarker. So does cognitive decline.

The Problem with Current Treatment

Conventional medicine tends to treat these symptoms in isolation. PDE-5 inhibitors amplify whatever nitric oxide remains, temporarily restoring erectile function without addressing the underlying deficiency. Stimulants increase arousal and attention without improving cerebral blood flow. The symptom gets masked. The cause persists.

The glycocalyx senses blood flow and initiates the signaling cascade that enables nitric oxide production. When it degrades, NO production fails. When NO production fails, high-demand organs become chronically underperfused and symptoms emerge.

Masking symptoms with pills leaves the underlying pathology in place. Restoring the vessel wall addresses the cause.

In the supplement space, several compounds are now being investigated for their ability to support glycocalyx integrity through similar mechanisms.

Most supplements don't target the glycocalyx. Multivitamins, antioxidants, and omega-3s address general metabolic needs but don't support the restoration of the vessel wall.

Structural restoration requires compounds that integrate into the glycocalyx, stimulate the body's repair pathways, and block the enzymes that break it down.

Two Examples

Rhamnan Sulfate comes from a green seaweed called Monostroma nitidum. Laboratory and animal studies suggest it works in three ways. First, it integrates directly into the glycocalyx mesh, filling in where the structure has thinned. Second, it stimulates the body's own production of glycocalyx components. Third, it blocks the enzymes that break the glycocalyx down.

Fucoidan comes from brown seaweeds. In vitro studies at Maastricht University suggest it may reinforce the glycocalyx where it has thinned, filling gaps in the barrier. It also activates repair pathways that speed vascular healing.

These are examples, not exhaustive prescriptions. The point is the mechanism: compounds that structurally integrate into the glycocalyx and activate repair pathways represent a different category of intervention than general-purpose supplements. The research is early, and randomized controlled trials evaluating cardiovascular outcomes have not yet been conducted. But the direction is clear.

The explanation lies in what standard testing doesn't measure. The glycocalyx, a microscopic layer lining every blood vessel, degrades years before conventional markers detect disease. Its failure permits LDL penetration, shuts down nitric oxide production, and initiates the inflammatory cascade that leads to plaque formation.

Erectile dysfunction, cognitive decline, and other symptoms are often early signals of this process, sharing a common mechanism: insufficient blood flow to high-demand organs.

Restoration is possible, however. Preclinical research points to compounds that may support glycocalyx integrity, though clinical validation is ongoing. Testing exists that evaluates the vessel wall itself rather than just what flows through it.

The path forward is to measure what standard panels miss, then provide what the vessel wall requires to rebuild.
