Provides mortality estimate in patients with ACS using only blood pressure, heart rate, and age.
Formula
TIMI Risk Index = Heart Rate*(Age/10) 2 /Systolic BP
Pearls / Pitfalls
A simple calculator to predict 30-day mortality, which has been well validated against a registry of 150,000 STEMI patients, and shown to have a very good discriminatory capacity. It was also validated against a registry of over 300,000 NSTEMI patients. It has been shown to both predict in-hospital and long-term mortality.
Advice
Mortality estimates may be useful in determining the level of care and intensity of treatment.
