What is a good Duke treadmill score?

Low risk (score > 5) indicates a 5-year survival of 97%. Intermediate risk (score between 4 and -11) indicates 5-year survival of 90%. High risk (score < -11) indicates 5-year survival of 65%. In high-risk patients, 74% had 3-vessel or left main occlusive coronary disease on angiography.

Is a Duke treadmill score of 10 good?

A Duke treatment score ⩾5 indicates low risk for cardiovascular events (predicted 4 year survival was 99%). This population does not need further investigation with coronary angiography. A score <–10 indicates high risk for cardiovascular events (predicted 4 year survival was 79%).

What is METs in treadmill test?

Treadmill protocol Exercise capacity is reported in terms of estimated metabolic equivalents of task (METs). The MET unit reflects the resting volume oxygen consumption per minute (VO2) for a 70-kg, 40-year-old man, with 1 MET equivalent to 3.5 mL/min/kg of body weight.

What is a good METs score on a stress test?

Exercise capacity is based on metabolic equivalents (MET) achieved, (one MET is defined as 3.5 mL O2 uptake/kg per min, which is the resting oxygen uptake in a sitting position). Less than 5 METS is poor, 5–8 METS is fair, 9–11 METS is good, and 12 METS or more is excellent.

How is the Duke Treadmill Score ( DTS ) calculated?

The Duke Treadmill Score (DTS) is a point system to predict 5-year mortality based on treadmill ECG stress testing in patients without known coronary artery disease. The Duke Treadmill Score is calculated as below: DTS = Exercise time (minutes) – (5 x ST deviation in mm) – (4 x angina index) The exercise time is based on using

Which is better Duke Treadmill Score or echocardiogram?

“Comparison of exercise echocardiography and the Duke treadmill score for risk stratification in patients with known or suspected coronary artery disease and normal resting electrocardiogram”. American Heart Journal. 151 (6): 1324.e1–1324.e10. doi: 10.1016/j.ahj

When to use the Duke Treadmill risk assessment?

Patients with an intermediate risk assessment should generally be referred for additional risk stratification with imaging modality 4). The Duke Treadmill Score incorporates both groups of prognostic markers (exercise capacity and exercise-induced ischemia) 5).

How is the Mets calculated on a treadmill?

The same equation used by the DTS group was applied to convert from Bruce minutes to METs: (Bruce minutes) = (METs + 2.2)/1.3. Pressure rate product (PRP or double product) pre-test and at maximal exercise were calculated as the product of systolic blood pressure and heart rate.
