Across the world, millions of people living with diabetes carry a hidden cardiac burden they cannot feel — their nerves dulled, their vessels quietly narrowing, their hearts deteriorating in silence. Medical experts are now confronting a paradox as old as medicine itself: the most dangerous damage is often the damage that announces nothing. In New Delhi and beyond, cardiologists are calling for a fundamental shift in how diabetes is managed, insisting that the absence of symptoms must never be mistaken for the absence of harm.
Diabetes a 'Silent Driver' of Heart Disease, Experts Warn of Hidden Cardiac Risk
Diabetic patients face significantly elevated risk of heart attacks and cardiac complications, often without awareness until emergency presentation or severe heart function decline.
They don't know they are being destroyed
Mark
So the story here is that diabetes causes heart disease—that's not new, right? What's the actual news?
Mimi
The news is how silent it is. Most people think of diabetes as a blood sugar problem. But these doctors are saying it's actively destroying your heart in ways you can't feel, and by the time you notice anything, you might already need surgery.
Luke
But how common is this? The story gives us one case—a 45-year-old man. Are we talking about most diabetics, or is this a worst-case scenario?
Mimi
Trehan says he's seen "many, many patients" with severely reduced heart function who didn't know it. But you're right—the story doesn't give us prevalence numbers. We don't know what percentage of diabetics end up like this man.
Mark
And the solution is just... more screening? Annual echocardiograms for every diabetic patient?
Mimi
That's what they're recommending. The idea is catch the damage before it becomes an emergency. But again, the story doesn't say how many people would need screening to prevent one emergency like this.
Luke
Also, the man in the case study was taking his diabetes medication irregularly. That's a huge variable. We don't know if he'd have had the same outcome if he'd been compliant.
Mimi
True. And he had no hypertension, which is unusual—most diabetics have multiple risk factors. So he might not be typical.
Mark
What about treatment? If screening catches this early damage, what can actually be done?
Mimi
The story doesn't address that. It's all about detection, not about what happens after you find the problem.
Luke
Right. The story is essentially saying "doctors should screen more," but it doesn't tell us whether early screening actually changes outcomes.
Mimi
That's the gap. The mechanism of damage is clear. The case is vivid. But the evidence that screening prevents emergencies—that's not in here.
Der Puls
- A 45-year-old man arrived at an emergency room believing he had indigestion — and discovered all three of his coronary arteries were nearly completely blocked, his heart surviving through a single threadlike channel.
- Diabetes silently destroys blood vessels through high blood sugar, insulin resistance, and inflammation, while simultaneously damaging the very nerves that would otherwise signal pain — stripping patients of their body's own warning system.
- Cardiologists now treat every diabetic patient as though they have already suffered a heart attack, a clinical stance that reflects just how profoundly the disease reshapes cardiac risk over time.
- Physicians have documented patients arriving with heart function reduced to just 20 percent — unaware of any problem until breathlessness finally drove them to seek an echocardiogram, years of deterioration already complete.
- Medical experts are now mandating regular cardiac screenings for all diabetic patients, arguing that the doctor must become the alarm system the patient's own body can no longer provide.
Across the world, millions of people living with diabetes carry a hidden cardiac burden they cannot feel — their nerves dulled, their vessels quietly narrowing, their hearts deteriorating in silence. Medical experts are now confronting a paradox as old as medicine itself: the most dangerous damage is often the damage that announces nothing. In New Delhi and beyond, cardiologists are calling for a fundamental shift in how diabetes is managed, insisting that the absence of symptoms must never be mistaken for the absence of harm.
Diabetes does its damage quietly. A 45-year-old man walked into an emergency room certain he was suffering from indigestion after a rich meal. His electrocardiogram revealed something far more grave: all three coronary arteries blocked, his heart sustained by a single fragile channel. He needed bypass surgery. He had felt nothing until that moment.
This is the paradox cardiologists are now urgently emphasizing. Dr. Ashwin Mehta of Sir Ganga Ram Hospital in New Delhi explains that high blood sugar sets off a cascade of injury — hyperglycemia, insulin resistance, and systemic inflammation that erode the inner lining of blood vessels through a process called endothelial dysfunction. Elevated cholesterol and triglycerides compound the damage, making vessel walls increasingly vulnerable to plaque. The man in the emergency room had lived with diabetes for roughly a decade, taking his medications irregularly, with no history of hypertension or prior cardiac events — yet his arteries had narrowed almost entirely without a single warning.
The silence, experts say, is the true danger. Dr. Naresh Trehan of Medanta hospital points to a cruel biological reality: diabetes damages the nerves responsible for transmitting cardiac pain. The body's alarm system fails. Trehan has seen patients arrive with heart function at just 20 percent, unaware of any problem until breathlessness finally prompted an echocardiogram — by which point years of silent deterioration had already run their course.
In response, cardiologists and diabetologists are now calling for mandatory cardiac screening. Trehan argues that physicians treating diabetes must take explicit responsibility for ordering regular echocardiograms — annually when concerns exist, every two years when the heart appears stable — because diabetic patients cannot trust their own bodies to warn them. The lesson is as simple as it is sobering: a person can be quietly destroyed and feel nothing at all.
Diabetes does its damage quietly. A 45-year-old man walked into an emergency room convinced he had indigestion from eating rich, fatty food. His electrocardiogram told a different story. All three of his coronary arteries were completely blocked. Blood was flowing through his heart via a single, threadlike channel in one vessel. He needed bypass surgery. When doctors explained what had happened, he was bewildered—he had felt nothing until that moment of discomfort he'd mistaken for gas.
This is the paradox that cardiologists are now emphasizing: diabetes is one of the most powerful drivers of heart disease, yet it often announces itself only when the damage is already catastrophic. Dr. Ashwin Mehta, who directs the Heart Failure Programme at Sir Ganga Ram Hospital in New Delhi, describes the mechanism with precision. High blood sugar triggers a cascade of injury. It causes hyperglycemia, which breeds insulin resistance and systemic inflammation. These conditions damage the inner lining of blood vessels—a process called endothelial dysfunction—by creating what doctors call glucotoxicity and by depleting nitric oxide, a chemical essential to vessel health. The damage doesn't stop there. Diabetes typically brings elevated cholesterol and triglyceride levels along with it, making vessel walls more vulnerable to plaque buildup. Hypertension and other metabolic problems often cluster alongside diabetes, compounding the cardiac risk further.
The numbers bear this out. Research has shown that over time, diabetes creates so much cardiovascular damage that cardiologists now treat every diabetic patient as though they already have coronary artery disease or have already suffered a heart attack. Mehta calls this a "myocardial risk equivalent"—a clinical way of saying that the risk profile is equivalent to someone who has already experienced a cardiac event. The man in the emergency room had been diabetic for around ten years. He took his medications irregularly. He had no history of high blood pressure. He had no prior heart attack. Yet his arteries had silently narrowed to the point of near-total blockage.
The silence is the real danger. Dr. Naresh Trehan, Chairman and Managing Director of Medanta hospital, points to a cruel biological fact: diabetes damages the nerves that signal pain from the heart. The body's alarm system fails. A person can suffer progressive heart damage without feeling chest pain—the classic warning sign of cardiac trouble. Trehan has seen patients arrive at his office with heart function reduced to 20 percent, unaware anything was wrong until they began feeling short of breath and finally got an echocardiogram. By then, years of silent deterioration had already occurred.
This is why cardiologists and diabetologists are now pushing for mandatory screening. Trehan emphasizes that physicians treating diabetes must ensure their patients receive regular cardiac evaluations—an echocardiogram annually if there are concerns, or every two years if the heart appears stable. The screening must happen because diabetic patients cannot rely on their own bodies to warn them. They don't know they are being destroyed, as Trehan puts it. The responsibility falls on the doctor to explain the cardiac risks explicitly and to order the tests that will catch damage before it becomes an emergency. A 45-year-old man eating spicy food should not have to learn in an emergency room that his heart is nearly dead.
