If coronary catheterization reveals significant coronary disease, what is the next step before elective noncardiac surgery?

• A. Aspirin therapy
• B. Beta-blocker optimization
• C. ACE inhibitors
• D. Revascularization

Answer: (D)

When significant coronary obstruction is found, the priority before elective noncardiac surgery is to restore adequate blood flow to the heart by revascularizing the affected vessels. This reduces the risk of perioperative myocardial ischemia or infarction, because the stress of surgery can overwhelm a myocardium with limited perfusion. Revascularization can be accomplished with coronary artery bypass grafting for complex, multivessel or left-main disease, or with percutaneous coronary intervention for focal lesions, chosen based on the anatomy and timing. After revascularization, the plan for noncardiac surgery can proceed with a safer margin, though the management of antiplatelet therapy and the timing of the surgery depend on the specific intervention performed. While aspirin, beta-blockers, and ACE inhibitors are important parts of ongoing medical optimization, they do not replace the need to relieve the obstructive coronary lesion before major elective surgery.
