Bova Score Calculator for Acute Pulmonary Embolism
x402
Bova Score Calculator for Acute Pulmonary Embolism is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the Bova 2014 seven-point risk index for normotensive (non-hypotensive) acute PE and returns a stage classification (I, II, or III) based on four clinical parameters.

How this service works
Bova 2014 seven-point index for confirmed acute PE that is not hypotensive: SBP 90–100 mm Hg +2 (SBP 100 scores; 101 does not; SBP <90 rejected), elevated troponin +2 (caller-assigned lab cutoff; magent does not grade assays), RV dysfunction on echo or CT +2, heart rate ≥110 +1 (110 scores; 109 does not). Max 7. Returns bands 0-2 / 3-4 / >4 (stages I–III) without mortality percents. Not a medical device and not a thrombolysis order.
Output
Returns the computed Bova score (integer 0–7) and the corresponding risk stage band: Stage I (0–2 points), Stage II (3–4 points), or Stage III (>4 points). Does not return mortality percentages and is not a thrombolysis recommendation.
Example use cases
Emergency PE triage in the ED
“I have a PE patient in the emergency department, systolic BP is 98, heart rate is 122, troponin is elevated, and echo shows RV dysfunction — can you compute the Bova score and tell me which risk stage they're in?”
Normotensive PE with borderline vitals
“My PE patient has a systolic BP of 100, HR of 109, no elevated troponin, and no RV dysfunction on CT — what is their Bova score and stage?”
Clinical documentation and handoff
“For handoff notes, calculate the Bova 2014 score for a PE patient: systolic BP 94 mm Hg, heart rate 110, elevated troponin yes, right ventricular dysfunction on CT yes — give me the total score and the stage band.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/bovaWhen to prefer
Use this endpoint when you need to programmatically compute the Bova 2014 risk score for a confirmed, normotensive acute PE patient (SBP ≥ 90 mm Hg) and classify them into Stage I, II, or III based on four discrete clinical parameters. Prefer this over general clinical calculators when you need structured, machine-readable stage output for downstream clinical workflows or documentation. Not suitable for hypotensive (high-risk) PE patients.
Side effects
- SBP < 90 mm Hg rejected (endpoint is for normotensive PE only, not hypotensive patients)
- Heart rate or SBP outside accepted numeric ranges returns an error
- Missing required query parameters (systolic_mm_hg, elevated_troponin, rv_dysfunction, heart_rate_bpm) cause validation failure
- Non-integer heart_rate_bpm value rejected
- Payment not fulfilled (x402 protocol) returns 402 status
