    TIMI Risk Index

    Provides mortality estimate in patients with ACS using only blood pressure, heart rate, and age.

    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.
