Duke Treadmill Score Calculator

DTS = exercise_min − 5·max_ST_depression − 4·angina_index.

Compute the Duke Treadmill Score from a Bruce-protocol exercise stress test: DTS = exercise time (min) − 5 × max ST-segment depression (mm) − 4 × angina index (0=none, 1=non-limiting, 2=limited test). Risk: ≥+5 low (4 % 5-yr CV mortality), −10 to +4 moderate, ≤−11 high (≥35 %).
