The Duke treadmill scoring (DTS) system confers better risk stratification and provides more substantial information about the different classification of risks in patients suspected of coronary artery disease (CAD) compared with conventional treadmill reading, according to a study presented at the Asian Pacific Society of Cardiology (APSC) 2019 A Duke Treadmill score <10 indicates high risk for cardiovascular events (predicted 4 year survival was 79%). In high-risk patients, 74% had 3-vessel or left main occlusive coronary disease on angiography. exercise is the duration of exercise expressed in minutes; ST-segment dev. ACC/AHA guidelines for exercise testing: executive summary. Duke treadmill scores typically range from -25 (highest risk) to +15 (lowest risk). Dr. A. Duke treadmill score = Exercise time (minutes) - (5 x ST deviation in mm) - (4 x angina index). 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. Duke Treadmill Test and Simple Treadmill Test are valid and well known scores which can predict coronary artery disease burden more efficiently than ST segment response alone. 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. Predicted Heart Rate Achieved: Rate Pressure Product: Duke Treadmill Score No calculation is presently available. A good time on a treadmill stress test is when the patient reaches their target heart rate. Angina or significant ST depression (greater than 2 mm) before completing Stage 2 of the Bruce protocol and/or ST depressions that persist for more than 5 minutes into recovery suggest severe ischemia and high risk for coronary events. In the article below to you will find more information about this coronary artery disease test and it's components.

Poor exercisers typically have lower exercise capacities due to poor muscle mass or limited cardiovascular ability; those in fair condition might have average muscles but may struggle with endurance events; while those in good condition tend to boast larger muscles as well as excellent cardiovascular health, making them capable of longer bouts of moderate-intensity work without tiring out quickly. The plaque, built from cholesterol and other substances, successively narrows the arteries, which limits the blood flow or can block it entirely. The 4xAngina Index (where 0 = no angina, 1 = non-limiting angina, 2 = exercise limiting angina) is a way of measuring heart health and describes the severity of coronary artery disease symptoms during physical activity. Its calculated by counting the number of calories burned in one hour and multiplying it by 8. Intermediate risk (score between 4 and -11) indicates 5-year survival of 90%. A Duke treatment score 5 indicates low risk for cardiovascular events (predicted 4 year survival was 99%). Their optimal management is not certain. The most widely used risk score that integrates these prognostic measures is the Duke treadmill score . Duke score = exercise 5 * ST-segment dev. Required fields are marked *. A significant difference was defined as a z-score >1.96, with z-score = (AUC 1- AUC 2) /(SE12 + SE22) 2. It also comes with a number of features, like automatic incline and decline, so you can customize your workout according to your needs.

These patients require further investigation with coronary angiography. Exercise was continued until the development of limiting symptoms (angina, dyspnea, or fatigue), abnormalities of rhythm (ventricular tachycardia or frequent couplets) or blood pressure, or marked and progressive ST-segment deviation (0.20 mV in the presence of typical angina or in the first stage of exercise). Patients with <1 mm of exercise-induced ST-segment depression should be counted as having 0 mm. Follow-up. Its calculated by taking the maximum exercise time and dividing it by the 5xST Segment Deviation in mm. This cookie is set by GDPR Cookie Consent plugin.

This population does not need further investigation with coronary angiography. Is a Duke treadmill score of 6 GOOD? If one or more of the coronary arteries feeding the heart contain plaques that block a blood vessel 70% or more, then an exercise stress test is needed. If any of these ECG abnormalities are noted, the test should be performed with the addition of an imaging modality.
