TIMI Risk Score for UA/NSTEMI

Thrombolysis in Myocardial Infarction (TIMI) risk score for Unstable Angina and Non-ST-elevation MI. Predicts 14-day risk of death, MI, or urgent revascularisation.

Used in: Acute Coronary Syndrome & Chest Pain

Score interpretation

High Risk — Early Invasive Strategy

→ TIMI High Risk (5–7): 14-day adverse event rate ~26–41%. Urgent coronary angiography within 2 hours if haemodynamically unstable; otherwise within 24 hours. Dual antiplatelet therapy; anticoagulation (UFH/enoxaparin); GPIIb/IIIa inhibitor if PCI planned.

Intermediate Risk — Early Invasive or Ischaemia-Guided

→ TIMI Intermediate Risk (3–4): 14-day adverse event rate ~13–19%. Coronary angiography within 24–72 hours; LMWH anticoagulation; dual antiplatelet; cardiology review.

Low Risk — Conservative Management

→ TIMI Low Risk (0–2): 14-day adverse event rate ~5%. Conservative management with aspirin; consider stress testing before discharge; cardiology follow-up.

Interpretation bands for the TIMI UA/NSTEMI. Apply clinical judgement and local guidance.
