Your arteries carry a biological age all their own, and it can sit decades above or below the number on your birth certificate. That single measurement predicts how long and how well you live better than any candle count.
Dr. Joel Kahn is an integrative and preventive cardiologist who first trained as a heart-attack specialist. His whole approach rests on one line from a 1600s medical textbook. A man is as old as his arteries. Alongside Dr. Helen Messier, a physician in integrative medicine, he reframes almost everything most of us assume about heart health.
This piece walks through what arterial age really means and how you find yours:
- Why the biological age of your blood vessels matters more than how old you feel
- How a scan costing under a hundred dollars reads that age directly
- Why normal cholesterol and a clean stress test can still hide real disease
- What actually shrinks plaque and turns arterial age back the other way
Start with the most unsettling fact, because it changes how urgently you act.
Why a healthy-looking person can still be in danger
Cardiovascular disease has led the causes of death across Western nations for more than a century, and for most of its long progression it produces no symptoms at all. A person can eat well, exercise daily, show normal cholesterol and normal blood pressure, and still carry severe hardened plaque inside their artery walls without the faintest clue. The worry that rides underneath that uncertainty is worth steadying too, which the tryit.tv free foundation course on calming your body and mind gently helps with.
Here is the fact that ought to change your calendar. Around 300,000 people a year in the United States die of sudden cardiac death as their very first symptom. Waiting for your body to announce the problem is a gamble with lethal odds.
That silence is exactly why the guiding rule of this whole field is so blunt. Test, do not guess.
How to read the true age of your arteries
The condition of your arteries can be pictured cheaply and painlessly, and the reading comes back as a number you can track. A coronary artery calcium CT scan costs roughly seventy-five to ninety-nine dollars, uses about the radiation of a routine mammogram, and needs no injection. It returns a calcium score and an estimated arterial age. A score of zero means arteries currently free of life-shortening disease. A high score means the opposite.
If you would rather avoid radiation, or you are young or pregnant, ultrasound gives the same answer. A carotid scan of the neck vessels reads arterial age with no radiation at all. Ultrasound of the femoral artery in the leg is quietly the most revealing of the set. Research in Madrid found it detects silent plaque in forty to fifty percent of people who are certain they are heart-healthy.
What none of the standard tests do is look at the artery wall itself. Blood pressure, cholesterol panels, blood sugar, even a stress test, all miss arterial age entirely. A stress test measures your fitness, not the state of your vessels, so passing one tells you far less than most people believe.
Why your cholesterol number cannot be trusted on its own
Two people can walk in with an identical high cholesterol reading and have opposite realities inside. Dr. Messier describes exactly this. One patient with an LDL around 200 has a calcium score of zero and clean carotid arteries, carrying little real risk. Another with the same number is severely diseased with a high arterial age. Same figure, opposite bodies. This is why imaging, not a lab value, must guide what happens next.
There is one inherited form of cholesterol worth knowing by name. Lipoprotein(a) is lifestyle-proof, meaning diet and exercise barely touch it, and it silently ages both your arteries and your heart valves. It affects roughly a quarter of people, which is more than a billion and a half worldwide. The test costs about thirty dollars, yet only around one percent of doctors think to order it. Anyone with a worrying family history has every reason to ask for it directly.
A fuller picture goes well beyond a single cholesterol figure. A complete cardiovascular panel draws roughly a hundred data points from one blood sample, adding inflammation markers, oxidative stress, heavy metals, vitamins, and optional genetic testing. The whole assessment, visit and blood work and imaging together, usually costs well under a thousand dollars and often under five hundred.
Turn your arterial age back toward younger
Here is the hopeful turn most people never hear. Arterial disease is not only preventable, it is reversible. Kahn documents a sixty-year-old whose arterial age of eighty fell to sixty-two over two years of focused intervention, confirmed on imaging. Arteries can genuinely grow younger.
The most striking case is a man named Paul, in his early fifties, with an LDL above 300, severe blockages, and a heart so enlarged he was near transplant. He left the Cleveland Clinic before open-heart surgery and reversed his disease through a whole food plant-based diet. His heart shrank back to normal, his leaky valves stopped leaking, and over a decade later he needed only a single stent. The nutritional work of Dean Ornish, Caldwell Esselstyn, and Nathan Pritikin shows this pattern holds, with soft plaque clearing within weeks on the right diet.
I have watched something close to this in the people I sit with. A body given the right conditions and a calmer nervous system often recovers faster than the timelines it was quoted. If you want to weigh your own numbers and next steps with someone alongside you, you can work through a heart-health decision that matters in a personal session with me. We take in both the medical picture and the worry underneath it.
Three evidence-based routes stop and reverse arterial ageing together. Nutrition clears soft plaque within weeks. Selective medication has its place, and it holds a surprise. Statins reduce heart attacks partly by an effect separate from lowering cholesterol, converting unstable soft plaque into stable hardened plaque, so some calcification can actually signal stabilisation. A newer class of injection called PCSK9 inhibitors, one of them Inclisiran, can push plaque to genuinely regress rather than merely holding the line.
What you can start looking into now
The third route is a growing toolbox of supplements and lifestyle tools that carry real human data behind them. Aged garlic has trials involving over a thousand participants. Pycnogenol, a French maritime pine bark extract, and vitamin K2 in its MK7 form, which helps direct calcium toward bone and away from arteries, both feature. Infrared sauna and niacin, a form of vitamin B3 that lowers lipoprotein(a), round out a set worth discussing with a knowledgeable doctor.
One last reframe keeps all of this in balance. Cholesterol itself is essential to life, building every steroid hormone, every cell membrane, and much of your brain. The goal was never to eliminate it. The goal is to know the real state of your arteries and act on what you find.
