Duke Treadmill Score
Duke Treadmill Score is a tool for predicting the risk of ischemia or infarction in the heart muscle. The score is a function of data from an exercise test: [exercise duration in minutes, by Bruce protocol] – [ 5 × (maximal ST elevation or depression, in millimeters)] – [4 × (treadmill angina index)] Angina index is zero if no pain occurs during the exercise, one if the pain is limited to the exercise period but the patient can continue the exercise (typical angina), and two if a pain is a reason to stop the exercise test.
