coronary: [17] Coronary comes from Latin coronārius, an adjectival derivative of corōna ‘garland, crown’. It was applied in the later 17th century to any anatomical structure, such as an artery, nerve, or ligament, that encircles another like a crown. A leading example of such a conformation is the heart, with its encircling blood vessels, and gradually coronary came to be used for ‘of the heart’.

Its application as a noun to ‘heart attack’ appears to be post-World War II. Other English descendants of Latin corōna (which came from Greek korónē ‘something curved’) include coronation [14], the diminutive coronet [15], coroner [14], originally an ‘officer of the crown’, crown, and of course corona [16] itself.
