Duke Treadmill Score is one of the tools for predicting the risk of ischemia or infarction in the heart muscle.<ref name=Alessi2010C12>,

 Pages: 109–18,</ref> The calculation is done based on the information obtained from an exercise test by this formula:

[exercise duration by Bruce protocol] - [ 5 × (maximal ST elevation or depression)] - [4 × (treadmill angina index)]

In which, the exercise duration is written in "minutes" and the ST changes in "millimetres".<ref name=Alessi2010C12/> Angina index will be zero if no pain appears during the exercise, one if the pain is limited to the exercise period (typical angina), and two if non-limiting pain occurs which will be a reason to stop exercise test.<ref>
