Mid 17th century (in the sense 'resembling a crown'): from Latin coronarius, from corona 'wreath, crown'.

  • In the 17th century coronary had the meanings ‘like a crown’ or ‘suitable for making garlands’, from Latin corona, ‘a crown or wreath’. In medical contexts the term came to refer to blood vessels, nerves, or ligaments that encircle a part of the body like a crown, in particular the arteries surrounding the heart. A coronary thrombosis, frequently abbreviated just to coronary, is a blood clot forming a blockage in one of these arteries. Other crown-related words that descend from corona are coronation (Late Middle English), coronet (Late Middle English), and coroner (Middle English) (originally an official responsible for safeguarding the private property of the Crown), not to mention the word crown itself.
