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 a normal Duke score?
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). The typical range is from +15 to -25 2).
Is a Duke treadmill score of 6 GOOD?
Patients were stratified into risk groups by the treadmill score according to the Duke classification (2). Patients with a treadmill score of ≥5 were classified as low risk, those with a score of <5 to −10 were designated as intermediate risk and those with a treadmill score of <−10 were classified as high risk.
What does a Duke treadmill score of 11 mean?
Duke treadmill scores typically range from -25 (highest risk) to +15 (lowest risk). 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% more or equal to 5: 0.25% / 97%
How accurate is Duke treadmill score?
A low-risk Duke treadmill score was associated with a 94% five-year survival, compared with 85% and 76% survival with intermediate- and high-risk scores (Figure 2)….Table 1.
| RR (95% CI) | P | |
|---|---|---|
| β-Blocker therapy | 0.56 (0.34–0.91) | 0.0191 |
| Duke score | ||
| High risk | 4.09 (1.62–10.33) | 0.0029 |
| Intermediate risk | 1.82 (1.31–2.54) | 0.0004 |
Is a Duke treadmill score of 13 good?
Duke treadmill scores typically range from -25 (highest risk) to +15 (lowest risk). 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%
Is a Duke treadmill score of 2 good?
The typical observed range for Duke treadmill score starts from -25 (the highest risk) up to +15 (the lowest risk)….The Duke score equation is as following:
| Treadmill angina index | Score |
|---|---|
| no angina/pain | 0 |
| typical angina (pain limited to the exercise period) | 1 |
| exercise stopped, because of angina | 2 |
What is the highest Duke treadmill score?
Duke treadmill scores typically range from -25 (highest risk) to +15 (lowest risk).
What is a good cardiac stress test score?
For adults, the maximum predicted heart rate is 220 minus your age. So, if you’re 40 years old, the maximum predicted heart rate is 220 – 40 = 180. For diagnostic treadmill testing, some doctors try to achieve about 85 percent of the predicted maximum heart rate.
What is the target heart rate for a treadmill stress test?
How is the Duke Treadmill Score calculated?
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 the standard Bruce protocol. ST deviation refers to maximum ST change (elevation or depression) in any lead except lead aVR.
What is the angina score for a Duke Treadmill?
Duke treadmill score. The angina index gives 0 points if no angina occurs, 1 point if non-limiting angina occurs and 2 points if angina occurs which limits exercise. Patients are categorized as low-, intermediate- or high-risk. Low risk (score > 5) indicates a 5-year survival of 97%.
What is the life expectancy of a Duke Treadmill patient?
Duke Treadmill scoring system predicts 5-year mortality, where low-risk scores have a 5-year survival of 97%, intermediate risk scores have a 5-year survival of 90%, and high-risk scores indicate a 5-year survival of about 65%.
What is the Treadmill Score used for?
This treadmill score is used for diagnostic and prognostic purposes for patients with suspected CHD. It is praised for accurate results in both inpatient and outpatient ischemic heart disease populations.
