Built to replace the reactive medical model — not fit into it.
ClearCardio™ wasn't created to fit into the current medical system. It was created to replace it — and to save 10 million lives over the next 10 years.
The mission
Heart disease is the #1 killer in America precisely because the system waits for symptoms. We invert the model: detect the disease in its silent phase with 640-slice CCTA + FDA-cleared AI, and reverse it with a personalized, physician-led plan — long before it ever causes a symptom. Because heart disease is largely genetic, 100% measurable, and in many cases totally preventable.
Dr. John OsborneFounder & Medical Director
"Heart disease is largely genetic, 100% measurable — and in many cases, totally preventable."
Why Dr. Osborne is unmatched
If you could choose any doctor on earth to prevent a heart attack — this is the one.
Dr. John Osborne holds a PhD in Cardiovascular Physiology and is nationally recognized for his expertise in how medications interact — especially for patients who are misdiagnosed, overmedicated, undermedicated, or unknowingly on drug combinations that work against each other. He was the first physician in Texas to adopt cardiac CT angiography, and he hasn't performed a heart catheterization in more than two decades — not because he couldn't, but because he found a better, earlier way.
His care doesn't stop at prescriptions: every prevention plan integrates lifestyle, nutrition, exercise, sleep, and stress management. For over 25 years he's studied the genetic roots of heart disease, proving that family history is not fate — as long as you act early. Surgery is his absolute last resort. His mission: save 10 million lives over the next 10 years.

I need ClearCardio today → The system is built to react — not prevent
Why most doctors wait for the emergency — and why that could cost you everything.
The modern medical system doesn't prioritize prevention. It prioritizes procedures — and the profits that come with them. Most cardiologists aren't trained to detect heart disease early; they're trained to intervene after symptoms appear. Because that's when the money flows:
- Heart catheterizations
- Stents
- Bypass surgeries
Each costs tens of thousands of dollars. But by then the disease is already advanced — and the root cause, microscopic rupture-prone plaque, has been ignored the whole time.
< 50 of 33,000 U.S. cardiologists
are board-certified in lipidology AND hypertension — the expertise you need to detect and reverse disease early.
~1,000 people worldwide
are trained and certified to accurately read and interpret cardiac CT angiograms — the only 640-slice scan that catches this plaque before symptoms.
So even if your doctor means well, chances are they're using outdated tools — and were never trained to read the one test that could save your life. If you've been told to "wait and see" based on a stress test, you've already been put at risk.

They did everything "right" — and still had plaque.

"I had no idea. No symptoms. If I didn't catch this now, I don't know what would've happened."
A 2023 calcium score came back positive but "not alarming." The CCTA revealed stage 3 disease.
