coronary
Adjective[C/U] Both
pl: coronaries
This term evokes a clinical, sterile environment and carries a heavy sense of medical urgency. It is rarely used in casual conversation unless referring to a medical diagnosis, as it focuses specifically on the anatomy of the heart's blood supply rather than the organ as a whole. In a social or emotional context, the word is almost never used. While heart-related terms like cardiac can be broader, coronary points directly to the plumbing of the heart, creating a mental image of narrow tubes and critical flow.
Countable when referring to a specific medical event (a coronary). Uncountable when used as an adjective to describe the anatomical system.
