A patient who recently had a myocardial infarction within the past 3 months with ongoing cardiac ischemia scheduled for noncardiac surgery. Which ASA class applies?

• A. ASA II
• B. ASA III
• C. ASA IV
• D. ASA V

Answer: (B)

In this context, the main idea is that ASA physical status reflects the amount of systemic disease and how it affects daily function, not just a history of disease. A recent myocardial infarction within the past three months flags significant cardiac disease, and ongoing cardiac ischemia indicates that the patient’s cardiac reserve is limited. If the patient is not currently unstable to the point of a constant threat to life and can be optimized for surgery, this combination is categorized as severe systemic disease with functional limitations, which corresponds to ASA III.

Think of it as: the patient has substantial cardiac disease and functional impact, but they are not in immediate, ongoing life-threatening instability at the moment. If there were persistent hemodynamic instability, refractory ischemia, or dependence on vasoactive support or mechanical circulatory assist, that would push the classification toward ASA IV.
