Rethinking Heart Attacks: Tom Cowan’s Radical Challenge to Modern Cardiology. Dr. Tom Cowan rejects the blocked artery theory of heart attacks, arguing that heart disease stems from metabolic failure, structured water, and energy loss. Discover his provocative challenge to mainstream cardiology.

For decades, the mainstream medical explanation for heart attacks and strokes has rested on a simple premise: arteries become blocked with cholesterol-laden plaque, blood flow is cut off, and tissue dies. Treatments have followed this model—statins to lower cholesterol, stents to open blockages, and bypass surgeries to reroute blood flow.

But what if this premise is flawed? What if blockages are not the primary cause of heart attacks, and strokes are not simply the inevitable result of clogged pipes? Dr. Tom Cowan, a physician known for challenging conventional assumptions, argues that the dominant model is not just incomplete but fundamentally wrong. In a sweeping critique, he reframes cardiovascular disease as an energetic and metabolic failure, not a plumbing problem.

The Problem with the Blockage Theory

According to Cowan, the blockage theory collapses under scrutiny. He points to several observations:

  • Other organs don’t have “attacks.” The spleen, liver, and kidneys share the same blood and arteries as the heart, yet no one suffers “spleen attacks” or “kidney attacks.” The heart and brain appear uniquely vulnerable, suggesting the cause lies in the organs themselves rather than in blocked blood vessels.
  • Patients with severe blockages function normally. Cowan recalls patients told they had 94% arterial blockages yet still managed to hike mountains. If blood flow were really limited to six percent of normal, such exertion would be impossible.
  • Autopsies don’t match the theory. Studies from the mid-20th century and the long-term work of pathologist Giorgio Baroldi showed that many people who died of heart attacks had no arterial blockage in the affected region. In fact, only about 18% of cases showed pre-existing blockages. In many others, the blockages appeared after the heart attack, likely as debris accumulated from tissue damage

These findings led Cowan to a stark conclusion: clogged arteries are not the real culprit.

An Alternative Explanation: Energy Failure, Not Plumbing Failure

If blockages don’t explain heart attacks, what does? Cowan proposes a model rooted in metabolic and energetic breakdown:

  • The role of glycolysis. When the heart can’t efficiently burn fuel, it shifts into glycolysis—a primitive, less efficient form of energy production. This creates a buildup of lactic acid, much like the cramp that forms when a muscle is overexerted. Unlike leg muscles, which can rest and flush out acid, the heart and brain cannot stop. Acid accumulates, tissue breaks down, and a heart attack or stroke occurs.
  • Why only the heart and brain? Both organs are energy-intensive and operate continuously. They cannot pause to recover, making them uniquely vulnerable to this cycle of metabolic collapse.
  • Collateral circulation. The body naturally grows new vessels to bypass obstructions. This adaptation undermines the narrative that blocked arteries doom heart tissue.

In Cowan’s framework, a heart attack is not a sudden failure of plumbing but a slow collapse of the heart’s metabolic resilience.

Plaque as the Body’s Intelligent Strategy

One of Cowan’s most provocative claims is that plaque is not the enemy. Instead, it is the body’s protective response to weakened arterial walls:

  • Structured water and the gel layer. Within arteries, a gel-like protective layer forms where proteins meet water. This layer, part of what biophysicist Gerald Pollack calls the “fourth phase of water,” helps maintain flow and protect vessels. Sunlight, grounding, positive emotions, and healthy living strengthen this layer. By contrast, toxins, EMFs, poor diet, and stress weaken it.
  • Plaque as patchwork. When the gel layer is compromised, the body applies plaque like cement to shore up fragile spots. While this reduces flow somewhat, it prevents vessel rupture.
  • The danger of medical intervention. Removing plaque with stents or surgery, Cowan warns, is like chiseling away cement from a cracked pipe: the structure may burst. In this view, plaque is an intelligent adaptation, not a deadly mistake.

High Blood Pressure Reconsidered

Cowan applies the same logic to hypertension. Instead of treating it as a disease, he sees it as another adaptive mechanism:

  • A weak “pump” (the body’s energetic and structured-water system) fails to maintain flow.
  • To compensate, the body narrows vessels, increasing pressure to sustain circulation.
  • Drugs that dilate vessels undermine this strategy, leading to fatigue, dizziness, and sexual dysfunction.

High blood pressure, Cowan argues, is not a pathology to be suppressed but a signal that the underlying energetic system needs repair.

The Heart Is Not a Pump

Perhaps Cowan’s most radical claim is that the heart is not a mechanical pump at all. He rejects the idea of the heart as a “pressure-propulsion device” that pushes blood through 10,000 miles of vessels. Instead, he describes it as:

  • A hydraulic ram and vortex generator. The heart receives blood, halts it momentarily, and creates a spiral motion. This vortex interacts with structured water to facilitate circulation.
  • Evidence from physics. Blood moves fastest as it enters and exits the heart but slows and shimmies in the capillaries—behavior inconsistent with simple mechanical pumping.
  • Energetic dimensions. The heart generates a measurable toroidal electromagnetic field extending six feet around the body. This field, Cowan suggests, is central to human connection and vitality, and its collapse precedes heart failure

From this vantage point, the heart is not the driver of circulation but the regulator and spiritual center of life.

From this vantage point, the heart is not the driver of circulation but the regulator and spiritual center of life.

Symptoms as Adaptive ResponsesCowan broadens his critique beyond cardiology. He frames many so-called “diseases” as the body’s intelligent responses to stress or injury:

  • Fever liquefies structured water to flush toxins.
  • Pus and inflammation expel splinters and debris.
  • Tumors package toxic waste the body cannot otherwise eliminate.

By suppressing these responses with drugs, Cowan argues, modern medicine often interferes with the body’s natural healing strategies.

Water, Structure, and Health

Central to Cowan’s theory is structured water—sometimes called “EZ water” or the fourth phase of water. He contends that health depends on maintaining this gel-like state inside cells and vessels:

  • When structured water is strong, energy flows, vessels are protected, and tissues thrive.
  • When it collapses, water pools as edema, joints swell, and circulation falters.
  • Sunlight, grounding, minerals, and positive emotions enhance structured water, while pollutants and electromagnetic fields degrade it.

Cowan’s practical advice includes seeking spring water, mineralizing it with natural salts, and energizing it through vortexing or special devices. He personally drinks little plain water, relying instead on fermentation drinks like beet kvass, believing the body produces much of its own “signature water” through metabolism.

The Four True Causes of Illness

In place of conventional diagnoses, Cowan reduces illness to four fundamental causes:

1.     Injury (physical trauma).

2.     Starvation (lack of food, water, love, or security).

3.     Poisoning (from pharmaceuticals, vaccines, toxins, EMFs).

4.     Delusion (false beliefs that lead to destructive choices).

He sees the last—delusion—as the most dangerous. Believing in false models, such as “viruses” or “cholesterol blockages,” leads patients to accept harmful treatments that worsen health.

Strengths of Cowan’s Perspective

  • Provocative critique. Cowan forces readers to reconsider assumptions and recognize inconsistencies in mainstream explanations.
  • Holistic integration. He connects cardiovascular health with diet, emotions, relationships, and environment.
  • Emphasis on adaptation. His reframing of symptoms as intelligent responses encourages respect for the body’s wisdom.

A Call to Think Differently

Tom Cowan’s ideas are bold, controversial, and unsettling. By challenging the blockage theory of heart attacks, the pump theory of the heart, and the disease model of medicine itself, he invites both practitioners and patients to think differently.

Whether one accepts his conclusions or not, his critique underscores an important truth: medicine must remain open to questioning its assumptions. Cardiovascular disease remains the leading cause of death worldwide. If our dominant paradigm has blind spots—as history suggests all paradigms eventually do—then asking hard questions is not just an intellectual exercise but a moral necessity.
