Gupta Perioperative Cardiac Risk (MICA)
Gupta MICA: predicted 30-day risk of perioperative MI or cardiac arrest from age, ASA class, functional status, creatinine, and procedure.

Example
- Age
- 65 years
- ASA physical status class
- III — severe systemic disease
- Functional status
- Partially dependent
- Serum creatinine
- Normal (≤ 1.5 mg/dL)
- Procedure type
- Intestinal
Result: Predicted 30-day risk of perioperative MI or cardiac arrest: 1.66% (linear predictor x = -4.08).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Use
- returns a predicted probability rather than a risk class; rcri is the complementary Lee class. A model estimate, not a clearance.
What you enter
- Age
- ASA physical status class
- Functional status
- Serum creatinine
- Procedure type
How this is calculated
- Model
- risk = 1 / (1 + e^-x); x = -5.25 + 0.02*age + ASA class + functional status + creatinine + procedure type. Reference categories (0): ASA V, independent, normal creatinine, hernia.
