It is based on the weighted index developed in 1987 as the result of a 2842 chest pain patient study. I have worked with many brands such as Adidas, Nike, Under Armour, and more to provide my customers with the best product for their needs.

Stage 2 is 2.5 mph and 12%, while Stage 3 goes to 3.4 mph and 14%. first minute after peak exercise, and by treadmill exercise score, defined as (exercise time) (53maximum ST-segment deviation) (43treadmill angina index). Duke treadmill score = maximum exercise time in minutes 5ST segment deviation in mm 4angina index (where 0 = no angina, 1 = non-limiting angina, 2 = exercise limiting angina). Yes, a Duke treadmill score of 7 is good and does not have a high risk for cardiovascular events. Duke Treadmill Score is a composite index which is used in the evaluation of symptomatic patients to predict the presence of coronary artery disease and their prognosis.

Patients with a Duke treadmill score between 4 and -11 are considered to have an intermediate response and still have decent chances for long-term survival, but they may experience some short-term side effects such as pain or fatigue during treatment.

Such baseline changes include ST-segment changes that are greater than or equal to 1 mm, left bundle branch block, ventricular paced rhythm, left ventricular or right ventricular hypertrophy, ventricular pre-excitation (i.e., Wolff-Parkinson-White syndrome), T wave inversions due to strain pattern or previous injury, conduction abnormalities and medication-induced ST-T wave changes. A Duke treadmill score is a measure of your cardiovascular fitness and can be used to predict how you will respond to stress testing.
