A Heart Surgeon's Heart Attack: The Numbers His Tests Missed
A cardiovascular surgeon who spent decades repairing hearts had his own heart attack despite looking fit and eating well. The hidden markers that told the real story, an ApoB of 180 and a fasting insulin of 40, were never on his standard panel. The conversation is a map of what to measure, when to start, and why prevention beats plumbing.
Overview
Mark Hyman sits down with Jeremy, a cardiovascular surgeon who spent twenty-five years doing bypasses before having his own heart attack. He looked healthy, exercised, ate well, and still fell into what he calls the gap between knowing better and doing better. His warning signs, chest discomfort on exertion that eased with rest, were classic, yet he explained them away for a full day before a single stent saved him.
Only afterward did deeper testing reveal the real story: a high baseline glucose, an A1c of 5.7, a fasting insulin of 40, and an ApoB of 180, none of which a standard cholesterol panel captures. The pair explore why ApoB and the triglyceride-to-HDL ratio predict risk far better than LDL alone, and why metabolic health drives most modern heart attacks. They reframe atherosclerosis as something we have from childhood rather than something we suddenly get, making early measurement and trend-tracking essential.
Jeremy separates local arterial-wall inflammation from the systemic environment, and explains how insulin resistance and visceral fat quietly weaken the endothelium. The practical close is refreshingly simple: a home blood-pressure cuff with the 7-2-2 rule, a waist-to-height ratio under 0.5, a handful of affordable labs, and the humility to measure before you assume you are fine.
Key quotes
5We know better, but so often, we just don't do better.
You can't fix what you don't measure.
The protocols are the practice of medicine. Knowing when and when not to apply those protocols is the art of medicine.
Atherosclerosis is something we have. It's not something we get.
We can save you. We can't heal you.
Key ideas
8The surgeon who had a heart attack
Jeremy spent decades treating the endpoint of heart disease. A decade after shifting toward prevention, and still doing everything he thought was right, he had his own event.
Classic signs, explained away
Chest discomfort on exertion that eased with rest is a textbook warning. As the self-described poster child of cognitive dissonance, he rationalized it as reflux for a full day.
The CGM revelation
A continuous glucose monitor, suggested by his son Max, exposed a high baseline glucose, an A1c of 5.7, and a fasting insulin of 40 when it should be under 5.
ApoB 180, the marker no one checked
ApoB bundles all the atherogenic particles and is now recognized as the strongest single predictor of heart risk, yet standard panels almost never measure it.
Beyond LDL
LDL is causal but not the whole story. The triglyceride-to-HDL ratio reflects metabolic health and predicts risk better; most modern heart attacks trace back to prediabetes.
A disease we already have
Autopsy studies show fatty streaks in children and early changes in young adults. The goal is to extend the runway, not to wait for symptoms.
Two layers of inflammation
Local inflammation at the arterial wall differs from systemic inflammation. CRP does not show wall-level plaque, but reflects the endothelial resiliency that guards against it.
Simple checks you can do at home
A blood-pressure cuff used with the 7-2-2 rule and a waist-to-height ratio under 0.5 are cheap, honest signals most people never track.
Practical takeaways
6- 1
Get a baseline early 23:00
Know your glucose, A1c, and fasting insulin in your 20s and 30s and follow the trend line rather than waiting for a crisis.
- 2
Ask for ApoB 28:00
It is the one biomarker the surgeon would pick for everyone; request it even if it is not on the standard panel.
- 3
Walk ten minutes after meals 55:00
Muscles take up glucose without needing insulin, so a short post-meal walk blunts the blood-sugar spike.
- 4
Pair cardio with strength 56:00
Each is powerful alone, but aerobic and resistance training compound dramatically when done together.
- 5
Measure blood pressure with the 7-2-2 rule 1:02:00
Seven days, twice a day, two readings each, then average; one reading at a visit is not enough.
- 6
Track waist-to-height ratio 1:02:30
Measure at the belly button and keep it under 0.5 as a simple proxy for visceral fat.
Topics & chapters
14The paradox
A cardiovascular surgeon who wants heart disease to drop to the number two killer describes having his own heart attack.
Just reflux
The morning it began, with symptoms he insisted were heartburn despite his wife's doubts.
Collapse in the woods
Severe chest pain a quarter mile from the truck, followed by a dangerous night taking aspirin and going to sleep.
Coming clean and the stent
His wife's hard words, the drive to a friend's office, and a single stent in the right coronary.
Unpacking the risk factors
Stress and disrupted sleep were real, but not enough to explain the event.
The glucose and insulin story
A CGM and labs reveal high baseline glucose, an A1c of 5.7, and a fasting insulin of 40.
ApoB 180
The atherogenic particle marker that standard cholesterol panels ignore.
Particle size and history
Ron Krauss showed decades ago that particle number and size track with carbohydrate intake, not fat.
The Lp(a) myth
Why a marker dismissed as untreatable is still worth knowing, and affordable testing through Function Health.
Two patients, one truth
Normal LDL and treated LDL can both end in the ambulance; the truth lies in metabolic health.
Protocols versus the art of medicine
Medication is not failure, and standard protocols are a starting place, not the full picture.
A disease we have
Atherosclerosis appears in childhood, and heart attacks were once rare before the modern diet.
Inflammation and the endothelium
Local arterial injury versus systemic inflammation, and what CRP really tells you.
What to check and rapid fire
Home blood pressure, waist-to-height ratio, key labs, and closing advice ending on ApoB.
