For illustrative purposes, the sample was divided into three groups: high risk (score < 10), moderate risk (10 to +4), and low risk ( + 5). The pain can be felt in your shoulders, arms, neck, jaw, abdomen and back. Duke Treatment Score is a measure of the severity of coronary artery disease (CAD). This population does not need further investigation with coronary angiography 6. In the original inpatient population, the Duke Treadmill score had a range from 25 (indicating the highest risk) to + 15 (indicating the lowest risk). A score of 5 or greater on a stress test shows that the patient has low risk for coronary artery disease. Interpreting exercise treadmill tests needs scoring system. Prognosis is determined in five steps: (1) The observed amount of exercise-induced ST-segment deviation (the largest elevation or depression after resting changes have been subtracted) is marked on the line for ST-segment deviation during exercise. Background: Exercise electrocardiography is a long-standing method for the evaluation of coronary artery disease (CAD), and it remains the initial test for most patients who can exercise adequately with a baseline interpretable electrocardiogram. Duke treadmill score (DTS) is well recognized as a simple prognostic score in patients with suspected coronary artery disease (CAD).1,2 It is positioned as a valid clinical tool when clinicians need to make a decision about the catheterization of patients with suspected CAD.

A partial or complete obstruction of your hearts arteries is the most common cause of reduced blood flow. The Duke Treadmill score uses three exercise parameters: exercise time, ST segment deviation (depression or elevation) and exertional angina to determine if patients are at a low, intermediate or high risk for ischemic heart disease 1.

Lack of blood flow through the hearts arteries is what causes a heart attack. The study found that the risk of death was highest in patients with a treadmill score between 22 and 26 percent, which is equivalent to walking at least 12 miles per week on average. This report should outline the baseline ECG interpretation, baseline heart rate, and blood pressure, ECG changes during exercise including the presence of arrhythmia/ectopy and the onset of such changes, maximal heart rate, and blood pressure during exercise, estimated exercise capacity in metabolic equivalents of task (METS) test, exercise duration and Stage completed, symptoms experienced during exercise and the reason for terminating the test. There is a positive test result when a diagnosis of coronary arteries disease is confirmed. It does not store any personal data. Duke treadmill scores can range from -25 to +15, depending on the risk. The Duke treadmill score evaluates various treatments, including surgery, chemotherapy and radiation therapy.
