Gupta Perioperative Risk for Myocardial Infarction or Cardiac Arrest (MICA)
Predicted probability of MI or cardiac arrest within 30 days of non-cardiac surgery.
Gupta Perioperative Risk for Myocardial Infarction or Cardiac Arrest (MICA)

Procedure type
Complete the fields above to see the result.
When to use
- Preoperative risk discussion and shared decision-making before non-cardiac surgery.
Formula
Logistic model: x = 0.02 x age + functional-status coefficient + ASA-class coefficient + creatinine coefficient + procedure coefficient - 5.25; risk (%) = e^x / (1 + e^x) x 100.
Pearls and pitfalls
- Derived from >200,000 patients in the American College of Surgeons NSQIP database.
- Procedure-type coefficients are the strongest driver of risk; aortic and cardiac surgery carry the highest added risk.
