Chest pain composite risk score: troponin band edges · case 02

Troponin exactly at the upper limit scores 1 and exactly three times the limit scores 2.

Case contract

Input {history 0-2, ecg 0-2, age, risk_factors (count), known_athero, troponin (ng/L), uln (ng/L)}. Toy points: age < 45:0, 45-64:1, >=65:2; risk factors 0:0, 1-2:1, >=3 or known atherosclerosis:2; troponin as a multiple of the upper limit (troponin/uln) <= 1:0, <= 3:1, > 3:2. Risk: 0-3 LOW, 4-6 MODERATE, 7-10 HIGH. Return {score, risk}.

Why this case matters

Composite chest pain scores sum banded components; age, override and troponin edges each fail on their own.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
troponin exactly at limit	`{"risk": "HIGH", "score": 7}`	`{"risk": "MODERATE", "score": 6}`	Failed
