TIMI Risk Score (UA/NSTEMI)
Estimates mortality and adverse outcomes in unstable angina/NSTEMI
- Highest activation tier
- Recommended
- How it is scored
- Scored in code; a detected disagreeing draft value is flagged for correction
- Care settings
- Emergency department, Inpatient
When it activates
Scribeable activates a calculator from the encounter. The TIMI Risk Score (UA/NSTEMI) can activate when the transcript or pasted chart context documents any of these:
- NSTEMI diagnosis
- Unstable angina
- ACS risk stratification
- Invasive vs conservative management decision
A coded diagnosis can also activate it. ICD-10 prefixes carried by the registry: I20.0, I21.4.
Note-type scope: it activates on notes whose subject resolves to cardiology, emergency medicine, critical care, hospital medicine. A note that resolves to another subject does not carry it even when the clinician's specialty matches; a note with no resolvable subject (a generic consultation) falls back to the specialty match.
Inputs the note needs
7 inputs. Each is resolved from the transcript, the pasted chart context and charted labs; at this calculator’s tier a missing input is never requested, and a missing required input keeps the score out of the draft.
| Input | Type | Unit / options | Guidance |
|---|---|---|---|
| Age >=65 years | age | Age 65 years or older (TIMI: 1 point). | |
| >=3 CAD risk factors | history | 3 or more CAD risk factors — HTN, hyperlipidemia, DM, smoking, family history (TIMI: 1 point). | |
| Known CAD (>=50% stenosis) | history | Prior coronary stenosis of 50% or more (TIMI: 1 point). | |
| Aspirin use in past 7 days | medication | Aspirin use within the past 7 days (TIMI: 1 point). | |
| >=2 anginal episodes in 24h | symptom | 2 or more anginal episodes in the past 24 hours (TIMI: 1 point). | |
| ST deviation >=0.5mm | exam | ST-segment deviation of 0.5 mm or more (TIMI: 1 point). | |
| Positive cardiac biomarker | lab |
Scoring
1 point each for: Age >=65, >=3 risk factors, known CAD, ASA use, severe angina, ST changes, positive marker. Max 7.
Age≥65 Age >=65 years + ≥3 risk factors >=3 CAD risk factors + known CAD Known CAD (>=50% stenosis) + ASA use Aspirin use in past 7 days + severe angina >=2 anginal episodes in 24h + ST changes ST deviation >=0.5mm + positive marker Positive cardiac biomarker
Interpretation
0-2: Low risk. 3-4: Intermediate. 5-7: High risk - consider early invasive strategy.

How Scribeable handles it in the note
When an encounter activates the TIMI Risk Score (UA/NSTEMI) (its highest tier is recommended), Scribeable does not ask you for missing inputs. The score is computed in code from whatever inputs resolve from the transcript, the pasted chart context or charted labs; a computed value is written into the draft only when every required input already resolves.
The score is computed in code from the resolved inputs, not recalled by the language model. If the draft states a TIMI Risk Score (UA/NSTEMI) value that disagrees with the computed one, the disagreement is flagged to the second drafting pass, which is instructed to correct the score and its interpretation before you see the note.
Classified as a risk score: activated strictly, by a documented trigger, never by a permissive reading of the encounter.
