Although they conclude that the Duke Treadmill Score is associated with adverse outcomes, a closer look at the data suggests otherwise. The Duke Treadmill score is calculated as follows 6: Duke Treadmill Score = maximum exercise time in minutes (5 ST segment deviation in millimeters during or after exercise) (4 the treadmill angina index [where 0 = no angina, 1 = non-limiting angina, 2 = exercise limiting angina]). The use of the Duke's treadmill score was further investigated in 1,872 patients equal to or above the age of 65 years, with a mean follow-up period of 6 years [46].
