Bypass surgery and stents may treat the consequences of cardiovascular disease, but what about the underlying causes? Russ Scala believes endothelial dysfunction deserves far more attention.

A Moment That Changed Everything

Russ was just six years old when he witnessed a man being hit by a car. He remembers standing there, wondering why nobody was helping him.

That image never left him. It became the thread running through everything that followed.

As a paramedic in the 1980s, Russ wasn’t just transporting patients. From 1984 to 1990, he was attached to a SWAT team, competing in events that combined running and shooting under pressure.

He was living a high-stress, high-physical-demand life from the inside.

And he began noticing something that didn’t fit the conventional medical narrative.

The Connection Between Stress, Cholesterol, and Heart Disease

In Russ’s experience, the people suffering cardiac events weren’t necessarily those with the worst diets or the highest cholesterol.

They were often the ones under relentless stress, training the hardest, and pushing their bodies beyond what the standard cardiovascular model seemed to explain.

This observation led him to question whether cholesterol alone could explain cardiovascular disease.

In 2006, almost a decade before the ketogenic diet became mainstream, Russ swam 12.6 miles around Key West while following that nutritional approach.

Not as a stunt, but as a personal experiment.

He wanted to test whether the metabolic framework he had been developing could withstand extreme endurance demands.

By then, Russ had already trained more than 400 physicians in nutrition and hormone replacement, worked as research director for one of the country’s largest compounding pharmacies, and spent time with heart transplant patients.

He had seen what happens when a heart is replaced but the underlying conditions affecting cardiovascular health remain unaddressed.

Understanding Endothelial Dysfunction: Looking Beyond Cholesterol

In his conversation with Dorian Yates, Russ explored an important but often overlooked aspect of cardiovascular health: the endothelium, the delicate inner lining of blood vessels.

They discussed the glycocalyx, a gel-like protective coating covering the endothelial surface.

This protective layer can be affected by factors such as abnormal blood-flow forces, metabolic dysfunction, and chronically elevated insulin.

When endothelial function becomes impaired, blood vessels may lose some of their ability to regulate blood flow, maintain elasticity, and support healthy circulation.

For Russ, understanding this lining is essential to understanding cardiovascular health.

Hormones, Nitric Oxide, and Arterial Health

Another important part of the discussion focused on the relationship between testosterone, estrogen, and nitric oxide.

Dorian had lowered his estrogen levels, and shortly afterward, experienced blood clots.

Russ questioned whether disrupting hormonal balance could contribute to vascular problems.

His perspective emphasizes the importance of the testosterone-to-estrogen relationship in supporting nitric oxide activity.

Nitric oxide is essential for helping blood vessels relax and maintaining healthy circulation.

Rather than focusing exclusively on individual hormone levels, Russ advocates examining the broader hormonal and vascular environment.

These hormonal relationships are complex, however, and altering estrogen or testosterone levels should not be considered a proven strategy for preventing blood clots or cardiovascular events.

Oxidative Stress: When Extreme Training Works Against the Body

Russ and Dorian also discussed oxidative stress and its effects on cardiovascular health.

One marker they explored was 8-hydroxy-2′-deoxyguanosine (8-OHdG), which is used to assess oxidative DNA damage.

Russ raised concerns about endurance athletes and bodybuilders who train intensely without adequate recovery.

Excessive physical stress may challenge the body’s antioxidant defenses, including:

• Glutathione
• Superoxide dismutase
• Catalase

These natural protective systems help defend cells against oxidative damage.

The concern is that athletes pushing themselves to extremes may, under certain conditions, overwhelm the very systems that help protect their cardiovascular health.

A Real-Life Example: Tony Smothers

Russ also shared the story of Tony Smothers, a man he had known for approximately ten years.

Tony had undergone triple bypass surgery and had elevated fibrinogen levels.

Russ described using a nitric oxide-focused program as part of Tony’s approach to cardiovascular health.

Tony also used microdosed testosterone, which Russ discussed in relation to nitric oxide signaling and red blood cell management.

The objective, according to Russ, wasn’t simply to address existing cardiovascular problems. It was to support the long-term health and elasticity of Tony’s arteries.

This is an individual account, not evidence that testosterone treatment prevents cardiovascular events. Testosterone can increase red blood cell counts and requires appropriate medical monitoring.

Are We Treating the Symptoms Instead of the Root Causes?

Across paramedic calls, triathlon finish lines, bodybuilding communities, and surgical recovery rooms, Russ kept observing patterns that challenged his understanding of conventional cardiovascular care.

For decades, cholesterol and dietary fat have dominated much of the public conversation about heart disease.

Russ believes the discussion needs to go further.

He points toward several interconnected factors:

• Endothelial function and vascular health
• Nitric oxide production and signaling
• Hormonal balance
• Oxidative stress and antioxidant defenses
• Metabolic health and insulin regulation
• Blood viscosity and vascular stress

His central message is that cardiovascular health cannot be understood through a single measurement or addressed through a single intervention.

Cholesterol, particularly LDL cholesterol, remains a well-established causal factor in atherosclerotic cardiovascular disease. Endothelial dysfunction is also important, and the two are not mutually exclusive.

Likewise, bypass surgery, stents, and cholesterol-lowering medications can provide important, sometimes lifesaving benefits, even when broader risk factors also require attention.

The Mission Continues

Russ’s story isn’t finished.

He’s still responding to emergency calls. Only now, those calls often come through a phone line.

His work has evolved from emergency medicine to research, education, and personalized health strategies.

He describes a research environment spanning 100,000 square feet and involving 20 PhDs.

Yet the question remains the same one he asked when he was six years old:

Why is no one helping?

That question continues to drive his interest in looking beyond symptoms and understanding the individual factors influencing health.
