Cardiac means “about the heart” as a body part — the organ that pumps blood — not about feelings or “heart” as in love. Doctors say cardiac arrest (the heart stops), cardiac surgery, a cardiac patient, the cardiac ward. You will hear it in hospitals, health news, and biology class. Informal English prefers heart: heart attack, heart problem, heart doctor. It is a cool, technical adjective, not a warm everyday one. Hospital talk sometimes uses cardiac as a noun for a heart patient (“a cardiac on the ward”), but the sense you are learning is the adjective: relating to the heart.
From the word’s history
From Middle French cardiaque, from Latin cardiacus, from Ancient Greek καρδία 'heart'.
源自拉丁文 cardiacus，來自古希臘文 καρδία「心臟」。
組成From French cardiaque, from Latin cardiacus, from Greek kardiakós “relating to the heart,” from kardía “heart.” On the surface: cardi- (heart) + -ac (relating to).
