Duke Treadmill Score is a tool for predicting the risk of ischemia or infarction in the heart muscle.{{cite book |first1=Ann Marie |last1=Alessi |chapter=Exercise Stress Testing |pages=109–18 |chapter-url={{Google books|F4lJGt0jr8MC|page=109|plainurl=yes}} |year=2010 |title=Nuclear Cardiology Technology Study Guide (Voice)| isbn=9780932004833 }} The score is a function of data from an exercise test:{{cn|date=October 2021}}
:[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.{{cite web |title=Duke Treadmill Score |url={{Google books|jyy7rceM4awC|page=172|plainurl=yes}} |page=172 }} in {{Cite book |doi=10.1007/978-0-387-76597-6_9 |chapter=Stratifying Symptomatic Patients Using the Exercise Test and Other Tools |title=Exercise Stress Testing for Primary Care and Sports Medicine |pages=167–192 |year=2009 |last1=White |first1=Russell D |last2=Goldschlager |first2=Nora |isbn=978-0-387-76596-9 }}{{cite journal |doi=10.1016/j.amjcard.2008.07.020 |pmid=18993164 |title=Age and Double Product (Systolic Blood Pressure × Heart Rate) Reserve-Adjusted Modification of the Duke Treadmill Score Nomogram in Men |journal=The American Journal of Cardiology |volume=102 |issue=10 |pages=1407–1412 |year=2008 |last1=Sadrzadeh Rafie |first1=Amir H |last2=Dewey |first2=Frederick E |last3=Sungar |first3=Gannon W |last4=Ashley |first4=Euan A |last5=Hadley |first5=David |last6=Myers |first6=Jonathan |last7=Froelicher |first7=Victor F }}
Duke treadmill scores typically range from –25 (highest risk) to +15 (lowest risk). One-year mortality and five-year survival rates respectively for the results of the Duke treadmill score have been reported as follows:{{cite book|url=https://www.stjoesannarbor.org/documents/mhvi/clinicalreferences/stable_pocket.pdf|title=Management of Patients With Chronic Stable Angina|date=March 2003|series=ACC/AHA Pocket Guideline|pages=49}}{{cite web|title=Duke Treadmill Score Calculator|url=https://www.thecalculator.co/health/Duke-Treadmill-Score-Calculator-1118.html}}
