Preoperative assessment for CABG includes evaluation of which of the following?

• A. A full dental exam only
• B. Assessment for S/S of angina or MI
• C. Vision testing only
• D. Preoperative anesthesia re-evaluation only

Answer: (B)

The main concept is that preoperative CABG planning centers on confirming cardiac stability by evaluating for signs and symptoms of angina or myocardial infarction. This matters because CABG carries a significant risk of perioperative myocardial ischemia, so identifying ongoing ischemia or a recent MI helps determine the timing of surgery and guides perioperative management. If a patient has active angina or recent MI, the team may optimize medical therapy, adjust the timing of the operation, or coordinate with cardiology for a revascularization plan, to reduce perioperative risk.

Other options don’t address the core risk the surgery aims to mitigate. A full dental exam, while potentially relevant for infection risk in some contexts, does not address the immediate cardiac stability required for CABG. Vision testing isn’t related to perioperative cardiac risk. A preoperative anesthesia re-evaluation is important as part of overall care, but focusing only on that would miss the crucial assessment of current cardiac status and ischemia that guides timing and management.
