Calculate cardiovascular risk based on exercise stress test results
About the Duke Treadmill Score
The Duke Treadmill Score (DTS) is a validated scoring system that predicts cardiovascular risk and survival in patients undergoing exercise stress testing. It incorporates exercise duration, ST-segment deviation, and exercise-induced angina.
Duke Treadmill Score Results
Calculation Formula
DTS = Exercise Duration (min) × 5.14
- ST-Segment Deviation (mm) × 4
- Angina Index × 8.04
Where Angina Index:
0 = No angina
1 = Non-limiting angina
2 = Exercise-limiting angina
- ST-Segment Deviation (mm) × 4
- Angina Index × 8.04
Where Angina Index:
0 = No angina
1 = Non-limiting angina
2 = Exercise-limiting angina
