The #1 cause of heart attacks can now be seen, treated, and reversed.
So why aren't more cardiologists talking about this?
Every 38 seconds, someone in the U.S. has a heart attack — and 40% are instantly fatal. The cause is soft plaque your stress tests, EKGs and calcium scores can't see. We find it years early with 640-slice AI cardiac imaging, read by one of the most qualified prevention cardiologists alive, and give you a plan to reverse it.

Heart attacks driven by soft plaque — invisible to stress tests, EKGs, and calcium scores.
“Fine”
What most people are told at their last checkup — weeks before the event no one saw coming.
Heart disease is the #1 killer in America — and almost no one sees it coming. It doesn't have to be you.
You've been lied to
The tests you trust were never designed to save you.
For decades, standard heart screenings — stress tests, EKGs, and even calcium scores — have lulled millions into a dangerous false sense of security. These tests can't see the real threat: they only detect blockages, the final stage of the disease, often after it's been silently growing for years.
But heart attacks rarely come from full blockages. They come from microscopic soft plaque rupturing without warning — hiding inside the artery wall where only a 640-slice cardiac CT angiogram (CCTA) layered with FDA-cleared AI can see it. The result of testing the wrong thing? Doctors wait. Insurance stalls. And people who "feel fine" and "pass every checkup" collapse without warning.
- The soft yellow areas are non-calcified, rupture-prone plaque
- AI maps exact narrowing points — including one at 76% diameter stenosis
- None of this would show up on a stress test
- In this scan, a calcium score would detect only 2% of the disease
This isn't prevention. It's reactive medicine, built to respond after the damage is done — and it's failing every 38 seconds.

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.
Your risks detected in as little as 7 days — apply now →The ClearCardio™ solution
Two questions that could save your life.
Before you trust anyone with your heart, ask this:
01
What data is being used to assess your risk?
If your doctor is still using a stress test, an EKG, or even a calcium score to "check your heart" — you're being assessed with the wrong data. Those tests were never designed to detect the real cause of heart attacks. At ClearCardio™ we use 640-slice cardiac CT angiography layered with FDA-cleared AI to do what no traditional test can:
- Quantify your total plaque burden — not just guess
- Pinpoint plaque vulnerability (the kind that ruptures)
- Map exactly where it is and how much it's growing
We're not looking for late-stage damage. We're catching the disease in its silent phase — and stopping it before it becomes fatal.
02
Who's interpreting that data — and are they qualified?
The best technology in the world means nothing in the wrong hands. Most doctors have never been trained to read a CCTA scan; almost none know how to treat what it reveals. That's why every ClearCardio™ patient works directly with Dr. John Osborne:
- One of fewer than 50 U.S. cardiologists triple board-certified in Cardiology, Lipidology, and Hypertension
- PhD in Cardiac Physiology — laser-focused on accurate, personalized treatment
- One of only ~1,000 people worldwide trained to read high-resolution cardiac CT scans
- 25,000+ CCTA scans read — more than most hospitals
- 25 years studying the genetics of heart disease — and how to reverse it
What gets measured gets managed. But only if the right doctor is looking at the right data.
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 → Who is ClearCardio™ for?
If you think heart disease only happens to "other people" — read this twice.
ClearCardio™ is for people who don't want to wait for a warning sign. For men and women who look healthy, feel fine, and pass their annual checkups — but refuse to gamble with their future. You may be doing everything right — but plaque doesn't care. It builds silently, microscopically, year after year… until it ruptures.
- Just because you're fit doesn't mean you're safe
- Just because you have no symptoms doesn't mean you have no plaque
- Just because you're in your 30s, 40s or 50s doesn't mean it isn't already happening inside your body
You're at elevated risk if even ONE of these applies to you:
You don't need symptoms to be at risk. You don't need a diagnosis to be in danger. And you won't need a second chance — if you look under the hood now.

Patient stories
They did everything "right" — and still had plaque.
4.5 / 5 · Trusted by patients nationwide
"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.

Not just a scan — a full-spectrum prevention system.
ClearCardio™ wasn't built around a test. It was built around a person — with the experience of 25,000+ advanced heart scans. If you're thinking "I can just get that scan somewhere else", you're missing the point: the scan is just the tool. What matters is what's being measured, who's reading it, and what they do next. The right scan in the wrong hands still leads to the wrong outcome.

The Hidden Killer in Your Arteries
Heart attacks and strokes aren't random events — they're preventable killers that don't care how busy you are building your life.
ListenQuestions, answered
Everything people ask before booking.
Is the scan safe? How much radiation is involved?
The 640-slice CCTA uses a fraction of the radiation of older scanners — typically comparable to a mammogram. The protocol is optimized per patient, and Dr. Osborne's team reviews whether imaging is appropriate for you before anything is scheduled.
I already had a calcium score of zero. Do I still need this?
A calcium score only sees hardened (calcified) plaque. The soft, rupture-prone plaque that drives most heart attacks is invisible to it. A zero score lowers risk but does not rule out disease — the CCTA sees both plaque types inside the artery wall.
How fast do I get results?
Most patients have real answers in as little as 7 days from their first consultation — including a personally-read scan and a reversal plan session with the team.
Is this covered by insurance?
ClearCardio is a concierge prevention program and is typically self-pay. Many patients use HSA/FSA funds. We'll walk you through options on your call — with zero pressure and full transparency.
Is my health information secure?
Yes. We operate under HIPAA with BAA-supported scheduling and storage systems. Your data is never sold or shared for marketing.
What if plaque is found?
That's exactly what the program is for. You'll get a personalized reversal plan — medication, lipids, nutrition, sleep, stress and inflammation — plus 12 months of concierge follow-up and re-testing to verify the plan is working.
Can't I just get a cardiac CT scan somewhere else?
Some places now offer cardiac CT scans — but the scan is just the tool. What matters is what's being measured, who's reading it, and what they do next. Most radiologists and cardiologists aren't trained to read high-resolution CCTA scans, let alone integrate AI analysis, genetic risk, lipid profiling and reversal protocols into one personalized plan. The right scan in the wrong hands still leads to the wrong outcome.
Why doesn't my cardiologist talk about this?
Most cardiologists are trained to intervene after symptoms appear — catheterizations, stents, bypass surgery — not to detect disease early. Out of 33,000 U.S. cardiologists, fewer than 50 are board-certified in lipidology and hypertension, and only about 1,000 people worldwide are certified to accurately read cardiac CT angiograms. Your doctor may mean well and still be using tools that can't see soft plaque.
