Gupta Perioperative Risk (Simplified)
Enter patient characteristics and planned surgery details to estimate risk of perioperative myocardial infarction or cardiac arrest.
Leave blank if unknown.
How to Use This Calculator
Confirm surgery type
Categorise the planned procedure as low, intermediate, or high cardiac risk per ACC/AHA guidelines.
Assess functional capacity and comorbidities
Functional independence, renal function, prior MI, and insulin-treated diabetes influence risk.
Interpret alongside clinical judgement
The simplified score provides a quick screen; corroborate with full NSQIP calculators when high precision is required.
Formula
This simplified score approximates the Gupta NSQIP model by weighting age, ASA class, functional status, renal dysfunction, surgical risk, and comorbidities. It categorises risk into low (<1%), intermediate (1–3%), or high (>3%) probability of perioperative myocardial infarction or cardiac arrest.
Full Description
The Gupta perioperative cardiac risk model, derived from the NSQIP registry, predicts myocardial infarction or cardiac arrest following noncardiac surgery. This simplified version offers rapid bedside stratification when the full online calculator is unavailable. Use it to frame discussions about risk, inform preoperative testing, and guide perioperative optimisation strategies.
Frequently Asked Questions
How does this compare to the official NSQIP calculator?
The official tool uses logistic regression with precise coefficients for many surgery types. This simplified score offers quick, approximate stratification when detailed calculators are impractical.
Should I order stress testing for high scores?
Consider further evaluation based on guideline indications—particularly if functional capacity is <4 METs or if the surgery is high risk.
What about urgent or emergent surgery?
Emergency procedures carry higher risk regardless of score. Optimise rapidly and involve multidisciplinary teams when possible.
Does beta-blocker therapy change the score?
Existing beta-blocker use is not directly included but may mitigate perioperative risk when continued appropriately.
