The test increases in speed and incline over the course of a couple of minutes. Angina or significant ST depression (greater than 2 mm) before completing Stage 2 of the Bruce protocol and/or ST depressions that persist for more than 5 minutes into recovery suggest severe ischemia and high risk for coronary events. Duke Treadmill Score was originally developed using data from 2842 consecutive inpatients referred to Duke University Medical Center between 1969 and 1980 with known or suspected coronary artery disease who underwent exercise testing according to the Bruce protocol 4 before diagnostic angiography who had both cardiac catheterization and treadmill exercise testing 5.
