To generate a more direct method of determining prognosis on the basis of data from treadmill exercise testing, the relations described by the treadmill score have been plotted as a nomogram (Figure 1) that provides an estimate of five-year survival or average annual mortality. Predicted Heart Rate Achieved: Rate Pressure Product: Duke Treadmill Score No calculation is presently available. The results of the original study were the following: The score results can help clinicians decide whether they need to refer outpatients with suspected coronary disease for cardiac catheterization. Exercise stress tests can lead to premature ventricular complexes. Patients with <1 mm of exercise-induced ST-segment depression should be counted as having 0 mm. What is the formula for calculating solute potential? Press ESC to cancel. The Duke Treadmill Score is a weighted index using treadmill exercise time (performed according to the standard Bruce protocol), maximum net ST-segment deviation (depression or elevation), and exercise-induced angina.

A Duke Treadmill score 5 indicates low risk for cardiovascular events (predicted 4 year survival was 99%). Although they conclude that the Duke Treadmill Score is associated with adverse outcomes, a closer look at the data suggests otherwise. high-risk (with a score of <= -11) categories. The Duke score is a measure of how risky a loan is and corresponds to the low-risk, moderate-risk and high-risk categories. The Duke Treadmill score can be used to determine if a patient is at a low, intermediate or high risk for cardiovascular disease.
