The word "heart" comes from Proto-Indo-European *ḱḗr. It started in Proto-Germanic *hertô. Then it appeared in Proto-West Germanic *hertā. Later, people used it in Old English heorte. After that, it was Middle English herte.
A word passing through this many languages survived because it named something universally important.
