Running keeps you fit. It doesn't guarantee clean arteries.
A fit, disciplined 37-year-old runner required emergency cardiac stents despite no conventional risk factors — a case that cardiologists across India are using to dismantle a deeply held cultural assumption. Physical fitness, however earnestly pursued, cannot override what is written in the genome or quietly accumulated through chronic stress and invisible inflammation. The heart's vulnerabilities often lie beneath the surface of standard medicine, in markers that are rarely measured and risks that are rarely named — until they become crises.
- A man who ran daily, ate well, and showed no traditional warning signs still developed severe coronary blockages — exposing a dangerous blind spot in how fitness is equated with heart health.
- Lipoprotein(a), a genetically inherited cholesterol particle that no lifestyle change can reduce, goes unmeasured in routine blood tests and silently accelerates plaque formation in arteries.
- Corporate stress, screen-lit sleepless nights, and chronic inflammation create a metabolic pressure cooker that standard checkups cannot detect — even in lean, active individuals.
- Cardiologists are urging Indians over 25 to demand advanced screening — ApoB, hs-CRP, homocysteine, coronary calcium scores — tests that exist but must be specifically requested, because the standard panel was never designed to find these threats.
A 37-year-old daily runner with no family history of heart disease, no high cholesterol, and no unhealthy habits found himself needing two coronary stents to clear severe blockages that had formed without a single warning sign. His cardiologist, Dr. Syed Akram Ali, has since used this case to challenge a widespread belief: that fitness protects the heart. It does not — not entirely.
The man's arteries were not clogged because he lived poorly. They were clogged because of Lipoprotein(a), or Lp(a) — a sticky cholesterol particle determined entirely by genetics, invisible on standard lipid panels, and impervious to exercise. If a father or uncle suffered an early heart attack, the inherited risk can be two to three times higher regardless of how lean or active a person is. Most people never discover their Lp(a) level because no one thinks to look.
Genetics, however, is only part of the picture. Dr. Rahul Gupta of Gleneagles Hospital Mumbai points to the modern corporate lifestyle as a second silent threat. Chronic stress raises adrenaline, drives inflammation, and causes microplaque to form in arterial walls. Poor sleep compounds this — cortisol rises, blood thickens, and plaques destabilize. None of it surfaces in a routine checkup. Elevated inflammation markers like hs-CRP, abnormal ApoB, insulin resistance, and high homocysteine all require specific, deliberate testing that most patients never receive.
Dr. Parin Sangoi of Wockhardt Hospitals reinforces the point: endurance and arterial health are not synonymous. Marathon runners can carry dangerous plaque. Young, lean people can be affected without a single symptom.
The cardiologists interviewed are unified in their recommendation — advanced screening must become standard practice. Anyone over 25 should know their Lp(a). Anyone over 35 should consider a coronary calcium score. A full cardiovascular picture requires tests that exist but must be asked for by name. Heart disease, as Dr. Gupta frames it, is not one cause but the sum of genes, inflammation, stress, sleep, and metabolic health together. Fitness is part of the answer — but the 37-year-old runner is proof that it was never the whole one.
A 37-year-old man ran five kilometers every day. He ate well. He had no family history of heart disease, no high cholesterol, no diabetes, no smoking habit. By every visible measure, he was doing everything right. Then he needed two stents placed in his coronary arteries to open severe blockages that had formed without warning.
This case, presented by cardiologist Dr. Syed Akram Ali, has become a teaching moment for a profession increasingly frustrated by a cultural myth: that fitness alone protects the heart. It does not. The man's arteries were clogged not because he failed to exercise, but because of something his genes had decided long before he was born—elevated levels of Lipoprotein(a), a sticky cholesterol particle that standard blood tests do not measure and that no amount of running can dissolve.
Lipoprotein(a), or Lp(a), is inherited. It is not something you acquire through poor diet or sedentary living. It is written into your cells. If your father or uncle had an early heart attack, your risk of the same is two to three times higher, even if you are lean and active. The problem is that most people never know their Lp(a) level because it does not appear on routine lipid profiles. A normal cholesterol panel can mask a genetic time bomb.
But genetics is only part of the story. Dr. Rahul Gupta, director and cardiologist at Gleneagles Hospital in Mumbai, points to a second invisible killer: the modern corporate lifestyle. Five kilometers of running does not undo chronic stress. Stress raises adrenaline and blood pressure. It triggers inflammation throughout the body. It causes microplaque to form in arteries. Add poor sleep—six hours a night with screens glowing until midnight—and the body enters a state of metabolic strain. Cortisol levels rise. Blood thickens. Plaques become unstable. None of this shows up in a standard checkup.
Inflammation itself, measured by a marker called hs-CRP, is often hidden in fit people. Many runners and gym-goers have elevated inflammation levels they never discover because their doctors are not looking for it. The same is true for elevated homocysteine, insulin resistance, and abnormal ApoB levels. These markers do not appear on basic tests. They require asking for them specifically.
Dr. Parin Sangoi, an interventional cardiologist at Wockhardt Hospitals in Mumbai, confirms that endurance and arterial health are not the same thing. A person can run marathons and still develop plaque in the coronary arteries. Genetic factors and high Lp(a) can accelerate plaque formation even when cholesterol numbers look normal. Young, lean individuals can be affected without any warning signs.
The solution, according to the cardiologists interviewed, is advanced screening that goes beyond the standard lipid panel. Anyone over 25 should know their Lipoprotein(a) level. Anyone over 35 should consider a coronary calcium score, which can identify early plaque before symptoms appear. Tests for hs-CRP, ApoB, homocysteine, fasting insulin, HbA1c, and vitamin D provide a more complete picture of cardiovascular risk. These are not routine. You have to ask for them. You have to know they exist.
Heart disease, Dr. Gupta emphasizes, is not a single cause. It is the sum of genes, inflammation, stress, sleep quality, and metabolic health combined. Fitness is part of the answer. It is not the whole answer. The 37-year-old runner learned this the hard way. The question now is how many others will learn it before they need stents.

If your father or uncle had early heart issues, your risk is 2–3× higher — even if you're fit, lean, and active.— Dr. Syed Akram Ali, cardiologist
A person may have good endurance but still develop plaque in the coronary arteries. Genetic factors, such as family history or high Lipoprotein(a) levels, can speed up plaque formation even when cholesterol levels seem normal.— Dr. Parin Sangoi, interventional cardiologist, Wockhardt Hospitals
The Hearth Conversation Another angle on the story
So the runner did everything right and still got blocked arteries. What was he actually missing?
He was missing knowledge of his own genetics. Specifically, he had high Lipoprotein(a)—a cholesterol particle that's purely inherited and doesn't show up on standard blood tests. No amount of running changes that.
But couldn't his doctor have caught this earlier?
Only if the doctor ordered the test. That's the real problem. Lp(a) isn't part of routine screening. Most people never know their level until something goes wrong.
So fitness is a false sense of security?
Not false, but incomplete. Running is good for the heart. But it can't override genetics, and it can't fix the damage that chronic stress and poor sleep cause. Those create inflammation that exercise alone doesn't address.
What does inflammation have to do with it?
Inflammation in the arteries makes plaques unstable and more likely to rupture. A fit person with high inflammation markers is at real risk, but they won't know it unless someone tests for it.
What should someone do differently?
Ask for advanced tests. Know your Lp(a), your inflammation markers, your homocysteine. If you're over 35, consider a coronary calcium score. Then manage stress and sleep as seriously as you manage your running schedule.
