A patient develops chest pain and ECG changes suggesting myocardial ischemia during the perioperative period. What is the initial management?

• A. Administer high-flow oxygen, obtain ECG/troponin, start aspirin if not contraindicated, consider nitroglycerin if blood pressure allows, and involve cardiology for guidance.
• B. Ignore and continue surgery.
• C. Only give morphine and observe.
• D. Administer beta-blockers immediately without assessment.

Answer: (A)

The initial approach to perioperative myocardial ischemia is rapid stabilization and diagnostic confirmation to prevent progression and guide definitive treatment. Start with high-flow oxygen to optimize oxygen delivery to the heart, then obtain an ECG and troponin to assess for an acute coronary syndrome. Give aspirin if there are no contraindications to help prevent further platelet aggregation and thrombosis. If blood pressure is adequate, use nitroglycerin to relieve chest pain and lower myocardial oxygen demand. Throughout this, involve cardiology for guidance on further management, including potential reperfusion strategies. This plan directly addresses the ischemia and provides a path forward, rather than ignoring the problem or delaying treatment. Options that involve continuing surgery, giving only morphine, or administering beta-blockers immediately without assessment fail to stabilize the patient or risk hemodynamic compromise.
