The publication of Traité de la structure du coeur, de son action, et de ses maladies in 1749 established a rigorous framework for cardiac analysis in eighteenth-century medicine. Jean-Baptiste de Sénac, a French physician and anatomist, transformed the rudimentary field of cardiology by systematically detailing the physiological and pathological complexities of the human heart through extensive autopsy-based research.
Education and Early Career
Born in 1693 in Lombez, France, Jean-Baptiste de Sénac pursued medical training at the Faculty of Medicine of Montpellier and Leiden University. He later expanded his knowledge in London under the instruction of John Freind. By 1723, he established a medical practice in Paris. His expertise and professional stature eventually led to his membership in the French Academy of Sciences, where he contributed to the scientific community as a chemist and anatomist.

Sénac occupied prominent positions within the French state during the reign of Louis XV. He served as the Premier médecin du roi from 1732 to 1752, acting as the personal physician to the monarch. His professional trajectory continued within the royal inner circle, where he served as a personal physician from 1752 until his death in 1770. Additionally, he held the political role of Councillor of State, reflecting his influence at the Palace of Versailles.
Advancements in Cardiology
The primary contribution of Sénac remains his systematic investigation into cardiac function. Through careful examination of cadavers, he identified the link between mitral valve disease and atrial fibrillation. He provided the first comprehensive documentation of cardiac hypertrophy. His clinical research also extended to experimental pharmacology, where he evaluated the efficacy of cinchona extract and rhubarb in treating cardiac irregularities. These observations were formalized in his 1749 treatise, which synthesized both his own findings and established medical diagnoses.
