Chest arthralgia is a disease characterized primarily by chest pain and a sense of blockage or constriction in the chest.Since the naming of “chest arthralgia”，medical practitioners throughout different historical periods have had varying interpretations of its definition and pathogenesis.By reviewing ancient medical books and exploring the academic thoughts of renowned doctors，this study attempted to trace the academic origins of chest arthralgia.In ancient times，the scope of chest arthralgia was broader and encompassed heart-related diseases such as coronary heart disease，as well as other chest and thoracic diseases.The theories regarding the causes and pathogenesis of chest arthralgia in ancient books were also quite rich，including Zhang Ji's influential concept of “weak pulse at yang and wiry pulse at yin”，which had a significant impact on subsequent generations.Additionally，various medical scholars elaborated on the causes of chest arthralgia from perspectives such as wind，cold，diet，phlegm，stasis，and clear yang.These ancient theories have provided a solid theoretical foundation and a wider range of treatment strategies for addressing modern chest and thoracic diseases.
