How this service works
Sgarbossa 1996 GUSTO-1 criteria for evolving AMI in left bundle-branch block: caller-assigned concordant ST elevation ≥1 mm (5), concordant ST depression ≥1 mm in V1–V3 (3), and discordant ST elevation ≥5 mm (2). Max 10. Score ≥3 had ~90% specificity in the derivation. Deterministic published score with citation; not a diagnosis, not the Smith modification, and magent does not read the tracing.
Output
Returns the total Sgarbossa score (0–10) based on the three Boolean criteria: 5 points for concordant ST elevation ≥1 mm, 3 points for concordant ST depression ≥1 mm in V1–V3, and 2 points for discordant ST elevation ≥5 mm. A score ≥3 had ~90% specificity for AMI in the original derivation cohort. The result is a deterministic arithmetic calculation; it is not a clinical diagnosis and does not reflect the Smith modification.
Example use cases
ED triage LBBB chest pain
“My patient came in with chest pain and has a left bundle-branch block — concordant ST elevation is present, no concordant ST depression in V1 through V3, and discordant ST elevation of 5 mm or more is also present. What's the Sgarbossa score?”
Clinical documentation assist
“I need to document a Sgarbossa 1996 score for this LBBB ECG: concordant ST elevation ≥1 mm is true, concordant ST depression in V1–V3 is true, and discordant ST elevation ≥5 mm is false. Compute the total points.”
Cardiology curbside consult
“Quick Sgarbossa check — no concordant ST elevation, no concordant ST depression in the right precordial leads, but discordant ST elevation of at least 5 mm is present. What score does that give me?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/sgarbossaWhen to prefer
Use this endpoint when you need a deterministic, citation-backed Sgarbossa 1996 score computed from caller-assigned Boolean ECG criteria for a patient with left bundle-branch block and suspected AMI. Prefer this over manual calculation to avoid arithmetic error in clinical workflows. Note this implements the original Sgarbossa 1996 thresholds (not the Smith modified ratio), so choose accordingly when the clinical context specifies which version is required.
Side effects
- Missing required Boolean parameter returns validation error
- Non-boolean value for any criterion causes schema rejection
- Network timeout on the magentlab API endpoint
- Caller misinterprets ECG findings — score reflects caller-assigned values, not actual tracing analysis
- Score of 0 or low score does not rule out AMI — endpoint provides no negative predictive guarantee
