MICA Cardiac Risk Calculator

Gupta Perioperative MICA Risk Model

The Gupta MICA (Myocardial Infarction or Cardiac Arrest) risk calculator evaluates a surgical patient's 30-day perioperative risk of experiencing intraoperative or postoperative myocardial infarction or cardiac arrest. Developed by Dr. Vikas Gupta and colleagues using multivariable logistic regression on data from over 200,000 surgical cases in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database, the MICA model is widely recognized alongside the Revised Cardiac Risk Index (RCRI).

The 5 Preoperative Predictors

Age: Advanced age increases cardiac risk continuously.
ASA Physical Status: Patient physical health classification (Classes I through V).
Functional Status: Categorized as independent, partially dependent, or totally dependent for activities of daily living (ADLs).
Serum Creatinine: Creatinine levels > 1.5 mg/dL (133 µmol/L) signal baseline renal impairment and elevated cardiovascular risk.
Surgical Procedure Category: Risk tier based on surgical complexity and hemodynamic stress.

Frequently Asked Questions

How does the Gupta MICA model compare to RCRI?

While the Revised Cardiac Risk Index (RCRI) uses categorical risk factors to yield a broad risk class, the Gupta MICA model incorporates continuous age and procedure-specific risk coefficients to provide a precise individualized percentage risk estimate for 30-day MICA.

What clinical actions should be taken for high risk scores?

Patients with elevated risk (> 1% to 3%) may benefit from preoperative cardiology consultation, non-invasive cardiac testing, optimization of beta-blocker/statin therapy, and postoperative telemetry monitoring.
