Coronary Artery Disease: History and Discovery

The story of coronary artery disease is not the tale of one discovery by one person on one day. It is a chain of careful observations stretching across more than two centuries, in which physicians first learned to recognize a chest pain (angina pectoris), then slowly connected that pain to diseased arteries feeding the heart, then proved that a person could survive a sudden artery blockage, and finally learned to see, reopen, and prevent the blockages themselves. Along the way, ideas that began as cautious hypotheses became established fact — and CT scans of ancient mummies revealed that hardened arteries are far older than the modern world. This page traces that cumulative journey, names the people who built it, and is careful to distinguish what each one actually discovered from what they only suspected. There was no single inventor of coronary artery disease, and no honest history pretends otherwise.

An Ancient Disease: Atheroma in Mummies

It is tempting to think of coronary artery disease as a purely modern affliction — a product of fast food, cigarettes, and desk jobs. The historical record complicates that story. Atherosclerosis, the build-up of fatty, fibrous, and calcified plaque inside artery walls that underlies coronary artery disease, is thousands of years old. Hardened, calcified arteries have been described in Egyptian mummies since the early twentieth century, when researchers such as the anatomist Marc Armand Ruffer reported arterial calcification in mummified tissue. The exact prevalence in antiquity, however, remained genuinely unknown for a long time, and we should be honest that early reports were limited by the tools of their day.

The most rigorous modern evidence comes from the Horus study, published in The Lancet in 2013 by Randall Thompson, Adel Allam, and colleagues. The team obtained whole-body CT scans of 137 mummies drawn from four very different ancient populations — ancient Egyptians, ancient Peruvians, the Ancestral Puebloans of the American Southwest, and the Unangan hunter-gatherers of the Aleutian Islands — spanning more than four thousand years. They scored arterial calcification as definite when a calcified plaque sat clearly within an artery wall and probable when calcification lay along an artery's expected path. Roughly a third of the mummies showed probable or definite atherosclerosis, and crucially it appeared in every population, including hunter-gatherers with no access to processed food.

The careful conclusion drawn by those authors is the one worth keeping: atherosclerosis is not solely a disease of modern lifestyles. That does not mean diet, smoking, and inactivity are irrelevant — they clearly accelerate the disease — but it does mean the basic biological tendency to lay down arterial plaque is part of the deep human condition. The history of understanding coronary artery disease, then, is the history of slowly recognizing something that was inside us all along.

Heberden Names Angina Pectoris (1768–1772)

The modern clinical story begins not with a cause but with a symptom — the chest pain itself. The English physician William Heberden (1710–1801) read a paper before the Royal College of Physicians in London in 1768, and published it in 1772 under the title Some Account of a Disorder of the Breast. In it he gave the condition the name by which it is still known: angina pectoris. His description is a model of clinical observation. He described people seized, usually while walking — especially uphill or soon after a meal — by a painful, strangling sensation in the chest that forced them to stop, and that vanished the moment they stood still. He noted that the pain often spread to the left arm, that men past their fiftieth year were most affected, and that some sufferers died suddenly.

What makes Heberden's account so important historically is also what limits it: he described the disorder without knowing its cause. He grouped patients by the pattern of their suffering, not by any understanding of the heart or its arteries; indeed, he was not convinced the heart was the seat of the problem. The cardiologist and historian Evan Bedford later called Heberden's paper "probably the most concise and precise original description of a new disease in the history of medicine" — high praise that nonetheless underscores the point. Heberden gave medicine a precise name and clinical picture for a syndrome, a vital first step, while the underlying mechanism remained a mystery to him.

This distinction — between describing a symptom and understanding the disease that produces it — runs through the whole history of coronary artery disease and is worth holding onto. For decades, angina pectoris was a recognized clinical entity in search of an explanation.

Jenner and Parry Find the Cause (1799)

The explanation began to take shape at the close of the eighteenth century, and it emerged from the friendship between two physicians: Edward Jenner (1749–1823), now far better remembered for pioneering smallpox vaccination, and Caleb Hillier Parry (1755–1822) of Bath. Performing autopsies on patients who had died with angina, Jenner noticed something striking — the coronary arteries, the small vessels that supply the heart muscle itself with blood, were hardened, narrowed, and in his word "ossified." He came to suspect that disease of these arteries was the hidden cause of Heberden's chest pain.

There is a poignant human reason Jenner hesitated to publish. His friend and former teacher, the great surgeon John Hunter, suffered from severe angina, and Jenner feared that announcing his theory — that the pain signified diseased, possibly fatal coronary arteries — would alarm Hunter and worsen his condition. Jenner held back. After Hunter died in 1793, the autopsy reportedly confirmed that his coronary arteries were heavily ossified, vindicating Jenner's suspicion. In 1799, Parry published the first dedicated monograph on the subject, An Inquiry into the Symptoms and Causes of the Syncope Anginosa, Commonly Called Angina Pectoris, which incorporated Jenner's observations and argued that the condition is caused by disease of the coronary arteries.

This is the conceptual hinge of the entire history: the moment when a symptom (angina) was first credibly linked to a cause (diseased coronary arteries). It is important to be accurate about its status, however. Jenner and Parry advanced a well-supported hypothesis grounded in autopsy findings; they did not have the tools to prove the mechanism in living patients, and the link between coronary disease and the dramatic event of a heart attack would remain disputed for another century. They identified the right culprit; the full case would take generations to assemble.

The Nineteenth Century: Thrombosis and Doubt

Across the nineteenth century, pathologists steadily built up the anatomical picture. The very word atheroma — from the Greek for "gruel," describing the soft, porridge-like core of a plaque — and the broader concept of arterial degeneration were refined by figures such as the German pathologist Rudolf Virchow (1821–1902), whose work on inflammation and on the factors predisposing to clot formation (later summarized as "Virchow's triad") shaped how generations thought about disease inside blood vessels. Autopsy after autopsy confirmed that coronary arteries could be narrowed, hardened, and blocked by clot — thrombosis — sitting on top of atheromatous plaque.

Yet a stubborn problem remained, and it concerned the heart attack itself. Around the turn of the twentieth century, the prevailing assumption among many physicians was grim and simple: sudden, complete blockage of a coronary artery (coronary thrombosis) was an event found at autopsy, because it was thought to be uniformly and rapidly fatal. The blockage was something you discovered after a patient had died of it. The idea that a person might suffer such a blockage, feel it happen, and then live — that the damaged heart muscle could scar over and the patient recover — was not part of mainstream thinking.

This blind spot mattered enormously for patients. If coronary thrombosis was assumed to be a death sentence, then there was little reason to diagnose it in the living, little framework for treating survivors, and little hope to offer. The stage was set for a single paper to overturn the assumption.

Herrick's Paradigm Shift (1912)

That paper came in 1912, when the Chicago physician James Bryan Herrick (1861–1954) published "Clinical Features of Sudden Obstruction of the Coronary Arteries" in the Journal of the American Medical Association. Herrick made the argument that would reshape cardiology: that sudden obstruction of a coronary artery produces a recognizable clinical syndrome in the living patient, and — the radical part — that this obstruction is not necessarily fatal. Patients could survive a coronary thrombosis. The dead muscle (the infarct) could heal into scar, and the person could go on living.

This is correctly remembered as a paradigm shift. It reframed the heart attack from an autopsy finding into a treatable clinical event, and it implied that there was something worth doing for these patients in the days and weeks after the attack — rest, observation, support — rather than simply pronouncing them doomed. Herrick later helped link the diagnosis to the new technology of the electrocardiogram, giving physicians a way to actually detect the event in real time.

The reception of his work is itself a lesson in how science advances. When Herrick first presented these ideas before the Association of American Physicians in 1912, the response was crushingly flat — by his own account the paper "fell like a dud." Honesty requires noting that Herrick was not, strictly, the first to suggest a survivable coronary thrombosis; earlier observers had hinted at it. But his paper became the influential, decisive statement the medical community eventually accepted, and it is rightly treated as the turning point — a reminder that even correct, important discoveries are often resisted before they are absorbed.

Learning to See the Arteries: Forssmann and Sones

Understanding that diseased coronary arteries caused angina and heart attacks was one thing; seeing those arteries in a living person was another entirely. Two acts of nerve and serendipity made it possible.

The first was a feat of self-experimentation that has become legendary. In 1929, a young German surgical trainee named Werner Forssmann (1904–1979), convinced a thin catheter could be passed safely into the human heart, performed the experiment on the only patient he could fully consent: himself. He anesthetized his own arm, threaded a flexible urinary catheter up a vein some 60 centimeters into the right side of his own heart, and walked to the X-ray department to document it. His superiors were appalled — one reportedly said he might lecture in a circus but not a respectable university — and his career in cardiology stalled. Decades later, after André Cournand and Dickinson Richards developed his technique into a practical diagnostic tool, the three shared the Nobel Prize in Physiology or Medicine in 1956. Forssmann proved the living heart could be reached by a catheter without killing the patient; he did not, by himself, create coronary angiography.

That step came from F. Mason Sones Jr. (1918–1985) at the Cleveland Clinic, and famously it happened by accident. On October 30, 1958, during a routine study of a young patient with rheumatic heart disease, the catheter unexpectedly whipped into the opening (ostium) of the right coronary artery just as contrast dye was injected, flooding the coronary artery directly — precisely the thing operators feared would trigger fatal ventricular fibrillation. The patient's heart instead stopped briefly; Sones shouted at him to cough, the heartbeat returned, and the patient was fine. Sones realized he had just done something thought to be impossibly dangerous and survived it: he had obtained the first selective coronary arteriogram, a clear X-ray image of an individual coronary artery in a living human. From that serendipitous moment, deliberate coronary angiography was born, finally letting physicians map exactly where and how severely arteries were narrowed.

Grüntzig Opens the Artery (1977)

Once the blockages could be seen, the obvious next ambition was to reopen them without major surgery. The breakthrough belongs to the German-born physician Andreas Grüntzig (1939–1985), who developed a tiny balloon mounted on the tip of a catheter that could be guided into a narrowed coronary artery and then inflated to crush the plaque outward and restore blood flow. He refined the idea painstakingly, building early balloon catheters partly on his own kitchen table.

On September 16, 1977, in Zürich, Switzerland, Grüntzig performed the first percutaneous transluminal coronary angioplasty (PTCA) on an awake human patient — a 38-year-old man with a tight, roughly 80% narrowing in the left anterior descending artery. The balloon dilated the diseased segment, blood flow was restored, and the patient did remarkably well; follow-up many years later found the treated artery still open. When Grüntzig presented his first cases at the American Heart Association meeting later that year, the field recognized at once that something fundamental had changed.

This single procedure founded the entire discipline of interventional cardiology — the catheter-based treatment of coronary disease that, refined with stents and other tools, now saves enormous numbers of lives during and after heart attacks. It is worth noting how recent this is: a disease recognized as angina in 1768 and traced to the coronary arteries in 1799 was not treatable by reopening those arteries until 1977. Grüntzig's career was cut short when he died in a plane crash in 1985, but the technique he originated had already transformed cardiology permanently.

Framingham and the Idea of Risk Factors

The history so far is about recognizing, seeing, and reopening blocked arteries — reacting to disease that already exists. A parallel and equally consequential strand of discovery asked a different question: who gets coronary artery disease, and why, and can we predict it before it strikes? The answer came largely from one long-running study.

The Framingham Heart Study began on September 29, 1948, when the first volunteer was examined in the town of Framingham, Massachusetts. (The study's creation owed something to national alarm over heart disease following the death of President Franklin D. Roosevelt from hypertensive heart disease and stroke in 1945.) Researchers enrolled just over 5,000 healthy adults and then followed them for decades, examining them repeatedly to see who developed heart disease and what those people had in common beforehand. This prospective cohort design — watching healthy people forward in time — was the key methodological innovation.

Framingham popularized the now-ubiquitous concept of the risk factor: a measurable trait that raises a person's probability of future disease. Over the following decades the study identified or confirmed that high blood pressure, high blood cholesterol, cigarette smoking, diabetes, obesity, and physical inactivity each raise the risk of coronary heart disease — findings so thoroughly absorbed into everyday medicine that it is easy to forget they once had to be discovered. This reframed coronary artery disease as something one could work to prevent, years before any chest pain, by managing the factors within reach. Modern risk calculators that estimate a person's ten-year chance of a heart attack are direct descendants of Framingham's data.

A Cumulative Discovery, Not a Single Inventor

Step back, and the shape of the whole becomes clear. No single person discovered coronary artery disease. Instead, the understanding was assembled piece by piece, and each contributor solved a different problem. Heberden (1768–1772) named and precisely described the symptom, angina, without knowing its cause. Jenner and Parry (1799) supplied the hypothesis of cause — that diseased coronary arteries were to blame — from autopsy evidence. Nineteenth-century pathologists like Virchow detailed the plaque and the clot. Herrick (1912) proved the heart attack was survivable, overturning a deadly assumption. Forssmann (1929) and Sones (1958) made it possible to see the arteries in living patients. Grüntzig (1977) learned to reopen them. And Framingham (from 1948) revealed how to predict and prevent the disease in the first place.

Two honest distinctions deserve emphasis, because they are easy to blur. First, describing a symptom is not the same as understanding a disease: angina was a recognized clinical entity for thirty years before anyone credibly tied it to the coronary arteries, and the coronary-cause idea remained a hypothesis for a century before it was fully established. Second, being influential is not the same as being first: Herrick's 1912 paper was decisive, yet earlier voices had hinted at survivable coronary thrombosis, and the cleanest history acknowledges them rather than crowning a lone hero. Serendipity, too, played an outsized role — Sones's arteriogram came from an accident recognized by a prepared mind.

This cumulative, multi-generational, error-and-correction character is not a footnote to the story; it is the story. Coronary artery disease — an ancient affliction visible even in mummies — was understood only through the patient, overlapping, sometimes-resisted work of many people across more than two hundred years. For the clinical picture, mechanisms, and current treatment of the disease itself, see the main Coronary Artery Disease page.
