Accuracy of non-invasive stress testing in women and men with angina in the absence of obstructive coronary artery disease. All patients should be monitored closely during the recovery period until heart rate, and ECG are back to baseline, as arrhythmias and ECG changes can still develop. Its based on five different measurements: heart rate, oxygen uptake, blood pressure, weight and waist circumference. 1997 Jul 1;96(1):345-54. https://doi.org/10.1161/01.CIR.96.1.345, Bruce RA, Hossack KF, DeRouen TA, Hofer V. . The Duke Treadmill score is a prognostic tool based on the duration of exercise, ST-segment deviation (depression or elevation), and the presence and severity of angina during exercise. Score requires the patient to undergo the Bruce protocol. The testing protocol could be adjusted to a patients tolerance, aiming for 6 to 12 minutes of exercise duration. The treadmill test was defined as positive if it yielded a score 11. Patients with a treadmill score of 5 were classified as low risk, those with a score of . The Duke Treadmill score is a prognostic tool based on the duration of exercise, ST-segment deviation (depression or elevation), and the presence and severity of angina during exercise. The Duke Treadmill score was developed to provide accurate diagnostic and prognostic information for the evaluation of patients with suspected coronary artery disease (coronary heart disease) who has undergone an exercise stress test. The exercise stress test usually takes 10 to 15 minutes, but part one can take up to 45 minutes. Failure of the blood pressure to increase or a decrease with signs of ischemia has a significant prognostic indication. The resting ECG is usually obtained both supine and standing, since patient position can influence the QRS and T wave axes. Duke Treadmill Score The score typically ranges from - 25 to + 15.
