1550 BCE, ancient Egypt — Ebers Papyrus (indirect cardiac references); modern clinical identification: 1958, Donald Teare, United Kingdom
Hypertrophic cardiomyopathy was a condition that confounded physicians for centuries, as its internal structural nature made it nearly invisible to the diagnostic tools available before the modern era. Early healers who encountered its effects often attributed the resulting deaths to mysterious cardiac failures or divine intervention. The formal recognition of the disease as a distinct pathological entity emerged only in the mid-twentieth century, representing one of the later chapters in the long history of cardiology.
Historical Narrative
For most of recorded medical history, the heart was understood through the lens of philosophy and gross anatomy rather than cellular pathology. Ancient Egyptian physicians, who documented cardiac observations in the Ebers Papyrus around 1550 BCE, understood the heart as a central vessel hub but had no means of detecting abnormal muscular thickening within its walls. Greek physicians, including Hippocrates, associated sudden deaths in otherwise healthy young individuals with imbalances of the four humors, particularly an excess of black bile or phlegm thought to obstruct the vital spirit coursing through the heart.
Galen of Pergamon, whose influence dominated Western medicine for over a thousand years, elaborated an anatomy of the heart based on animal dissections. His writings described the heart's muscular substance in considerable detail, yet his framework offered no conceptual category for a condition defined by asymmetric hypertrophy of the interventricular septum. Medieval Islamic physicians such as Ibn Sina, whose Canon of Medicine synthesized Greek and Arabic learning in the eleventh century, similarly described cardiac ailments through humoral and pneumatic theories, classifying mysterious sudden cardiac deaths among the young as arising from corrupted vital spirits or excessive heat within the cardiac chambers.
The Renaissance brought a revolution in anatomical understanding. Andreas Vesalius, in his landmark 1543 work De humani corporis fabrica, produced detailed illustrations of the heart's musculature, correcting many Galenic errors. Yet even with improved anatomical knowledge, the subtle thickening characteristic of hypertrophic cardiomyopathy remained beyond detection without microscopic tools and was not identified as a distinct pathological process.
William Harvey's 1628 demonstration of blood circulation fundamentally reframed how physicians thought about cardiac function, opening the door to understanding the heart as a mechanical pump subject to structural failure. Through the seventeenth and eighteenth centuries, post-mortem examinations became increasingly systematic, and physicians such as Giovanni Battista Morgagni, whose 1761 masterwork De Sedibus et Causis Morborum catalogued hundreds of pathological findings, began correlating enlarged hearts with clinical histories of sudden death. Morgagni described cases of unusually thickened and firm cardiac muscle in patients who had died unexpectedly, laying an early foundation for recognizing that the heart's muscular walls could undergo pathological transformation.
The nineteenth century saw pathological anatomy flourish, with figures such as Rudolf Virchow advancing the understanding of disease at the cellular level. However, the asymmetric septal hypertrophy that defines the condition continued to be lumped under broader categories of cardiac hypertrophy or described as idiopathic heart disease. It was not until 1958 that the British pathologist Donald Teare published a landmark description of asymmetrical hypertrophy of the heart in a series of young patients who had died suddenly, marking the first clear delineation of what would eventually be named hypertrophic cardiomyopathy. Teare's observations, drawn from careful post-mortem analysis, catalyzed an era of clinical and pathological investigation that transformed physician understanding of the condition from a mysterious scourge of the young into a recognizable structural entity.
