❤️ TIMI Risk Score (UA/NSTEMI)

Estimate 14-day risk of death, MI or urgent revascularisation in UA/NSTEMI with the TIMI score.

TIMI Risk Score (UA/NSTEMI)

Age ≥ 65
≥ 3 CAD risk factors
Known CAD (stenosis ≥ 50%)
Aspirin use in past 7 days
≥ 2 anginal episodes in 24 h
ST deviation ≥ 0.5 mm
Elevated cardiac markers

When to use

Risk-stratify non-ST-elevation acute coronary syndromes.

How it works

1 point each: age ≥ 65, ≥ 3 CAD risk factors, known CAD, aspirin in 7 days, ≥ 2 anginal episodes/24 h, ST deviation ≥ 0.5 mm, elevated markers.

Key points

  • Higher scores favour an early invasive strategy.
  • Score 0–1 ~5%, 6–7 ~41% 14-day event risk.
  • Use alongside troponin trend and clinical context.
