A patient had a myocardial infarction (MI) 8 months ago. What is their ASA classification?

  1. ASA I
  2. ASA IV
  3. ASA III
  4. ASA II
Show answer and explanation

Correct answer: C. ASA III

  • A. ASA I: completely healthy patient with no systemic disease.
  • B. ASA IV: severe systemic disease that is a constant threat to life — e.g., recent MI (< 6 months), unstable angina.
  • C. Correct. A patient who had an MI 8 months ago is ASA III: severe systemic disease that is not immediately life-threatening. Note: an MI within the LAST 6 months would be ASA IV (major risk with significant threat to life). 8 months ago makes it ASA III.
  • D. ASA II: mild systemic disease — a controlled, stable condition (e.g., well-controlled hypertension, mild asthma).
