The term "cardiac" has been employed in literature to reference both anatomical regions and functional aspects of the heart. For instance, early works used it to describe specific anatomical parts, like the chick-embryo's heart region and the configuration of organs, as seen in [1], [2], [3], and [4]. In medical and therapeutic contexts, "cardiac" has also been attached to discussions on treatment modalities—ranging from stimulants and antispasmodics used for conditions of collapse and dyspnea ([5], [6]) to substances recognized as poisons or depressants that affect heart function ([7], [8], [9]). Moreover, its application even spans observations on the cardiac effects of everyday substances like caffeine, as indicated in [10], and extends to taxonomic notes in botanical texts ([11]). This varied usage underscores the word's dual role as an anatomical descriptor and as a marker of physiological effect across different fields and historical periods.
