The abbreviation for coronary artery bypass graft is which?

• A. CABG stands for coronary artery bypass graft
• B. Coronary artery bypass graft
• C. CABG
• D. Cardiac artery bypass graft

Answer: (C)

Abbreviations from medical terms are usually built from the initial letters of the main words. For coronary artery bypass graft, the key words are Coronary, Artery, Bypass, Graft. Taking their first letters gives C, A, B, G, which together form CABG. This is the standard shorthand used in cardiology and surgical contexts to refer to the procedure. The full term on its own isn’t an abbreviation, and using “Cardiac” instead of “Coronary” isn’t the same term, so it wouldn’t be the accepted abbreviation.
