Cardiac Data Requirements & Gap Analysis

The AI model reads 32 clinical parameters — this page shows exactly which ones, how they're coded, and what happens when your bundle is incomplete.

The CardioExplorer AI model was trained and validated on 32 clinical parameters — demographics, vitals, routine labs, cardiac markers, medications and symptoms.

Why 32 parameters?

Coronary risk isn't visible in any single value. The model finds signal in the combination of routine measurements — a lipid panel interpreted alongside blood pressure, glucose, inflammatory markers and current medication. All 32 inputs come from data most clinics already collect, so no additional testing is required.

You don't need a perfect bundle to get started: the system accepts partial data, tells you precisely what's missing, and lets clinicians complete the remainder in the UI.

How your bundle is processed

Every response tells you where each of the 32 parameters landed:

✅

itemsMapped

Recognized and valid — stored on the draft test, ready for the model run.

❌

itemsRejected

Sent but refused: unknown code, invalid status, or out-of-range value. Each entry carries the offending entry's fullUrl in entryUrl and the cause in rejectionReason.

⭕

itemsMissing

Expected by the model but absent from the bundle — supply via API, or let a clinician complete it in the UI.

⚠️ Warning: Follow the data-freshness rules from the Instructions for Use — laboratory values no older than 90 days; blood pressure, height and weight no older than 30 days. Always send a valid ISO-8601 effectiveDateTime and query your EHR for the most recent values.

The 32 parameters — reference table

All quantitative observations use LOINC codes with UCUM units; symptoms use SNOMED CT; medications use CardioExplorer therapy codes.

Demographics & vitals (6)

#	Parameter	FHIR source	Code	Unit / values	Max age (IFU)
1	Sex	Patient.gender	—	male / female	—

ℹ️ Note: Medication statements map to Yes only when status: "active" and a valid effectiveDateTime are present. Any other status (stopped, completed, not-taken…) maps to No.
