Duke Treadmill Score The equation for calculating the Duke treadmill score (DTS) is, DTS = exercise time in minutes - (5 x ST deviation in mm or 0.1 mV increments) - (4 x exercise angina score), with angina score being 0 = none, 1 = non limiting, and 2 = exercise-limiting. You also have the option to opt-out of these cookies. The range is usually between +15 and -25. The cardiac risk is very low even after test findings.

The 5-year survival of 97% is shown by the low risk score. Background: Although the Duke treadmill score is generally effective for risk stratification, its prognostic value in the elderly may be limited because they have a higher prevalence of coronary artery disease (CAD), more . In high-risk patients, 74% had 3-vessel or left main occlusive coronary disease on angiography. The predicted 4 year survival was 99% which shows that this type of exercise has a long-term positive effect on health. One of the comments is that low scores in female patients are better at excluding ischemic heart disease than in male patients. ST deviation refers to maximum ST change (elevation or depression) in any lead except lead aVR; and. The use of the Duke's treadmill score was further investigated in 1,872 patients equal to or above the age of 65 years, with a mean follow-up period of 6 years [46]. Is a Duke treadmill score of 10 good? All subjects have undergone treadmill testing cardiac catheterization. Once it is determined that there are no limiting factors based on baseline ECG, the patient is placed on a treadmill with a designed protocol that increases in intervals as you exercise. By gradually increasing the intensity of the physical activity, a person's maximum METs is measured. Stage 1 of the Bruce protocol is performed at 1.7 miles per hour and a 10% gradient. high-risk (with a score of <= -11) categories. Also known as the exercise tolerance test, it is used to estimate endurance athletes' overall fitness or to detect weak heart conditions. Duke Treadmill Score Requires Bruce Protocol. Indications for terminating the test include if the patient request to stop due to severe symptoms (i.e., chest pain, shortness of breath or fatigue), severe exercise-induced hypotension or hypertension, horizontal or downsloping ST depression of greater than or equal to 1 mm or ST-segment elevation, new bundle branch block, AV block, ventricular arrhythmia, if patients achieve their maximal heart rate or all stages have been completed. A Duke treadmill score greater than 5 means that you have a low risk of developing heart disease. Consuming anything that has a lot of energy in it. One-year mortality and five-year survival rates for the results of the Duke treadmill score have been reported as less or equal to -11. The purpose of this prospective study is to determine mortality and nonfatal cardiac events in patients at either intermediate pretest risk for CAD or patients with known CAD, achieving 10 METS regardless of peak exercise heart rate. High risk (score < -11) indicates 5-year survival of 65%. Patients should be questioned about any symptoms they experience during exercise. This nomogram applies to patients with known or suspected coronary artery disease, without prior revascularization or recent myocardial infarction, who undergo exercise testing before coronary angiography 7.

INTRODUCTION The Duke Treadmill Score has been well vali-dated and widely used for many years as a powerful prognostic marker in patients being evaluated for coronary artery . The more powerful antiarrhythmic drugs are more likely to be effective than less powerful ones. The Duke treadmill score 1, 2 was calculated as: exercise time (5 maximum ST deviation) (4 angina index). 4 * TAI. One-year mortality and five-year survival rates respectively for the results of the Duke treadmill score have been reported as: less or equal to -11: 5.25% / 65% 4 to -10: 1.25% / 90%. 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. Although the cardiac mortality of the high-risk group of the elderly (4.4 . However, this tool can never replace professional medical advice. The most widely used risk score that integrates these prognostic measures is the Duke treadmill score . More than 70% of high-risk patients had a 3-vessel or left main occlusive coronary disease on their angiogram. The Duke Treadmill score can be used to determine if a patient is at a low, intermediate or high risk for cardiovascular disease. Adults rate their stress level as 5.1 on a 10-point scale, where 1 is little or no stress, and 10 is a great deal of stress, which is up from 5.1 in the previous year. 5 indicates low risk for cardiovascular events (predicted 4 year survival was 99%).
