Yes, a 9-minute treadmill stress test is good for people with low cardiac risk because it allows them to see how well their heart responds to stressful conditions. A good score on a stress test is one that simulates the conditions you will see in a typical drivers situation. To generate a more direct method of determining prognosis on the basis of data from treadmill exercise testing, the relations described by the treadmill score have been plotted as a nomogram (Figure 1) that provides an estimate of five-year survival or average annual mortality.

There are certain ECG and imaging changes that would support this conclusion. However, there is little information about the relationship between Duke treadmill test score (DTS) and severity of coronary artery lesion, as well . At what percentage does a stress test identify a blockage? In high-risk patients, 74% had 3-vessel or left main occlusive coronary disease on angiography.

A normal Duke treadmill score is a number that indicates the risk of developing heart disease. Angina is chest pain caused by a lack of oxygen-rich blood in the heart. Duke treadmill score = (Exercise duration [minutes]) - (5 ST deviation [mm]) - (4 angina index) Angina index: 0 = no angina, 1 = nonlimiting angina, and 2 = exercise limiting angina. This is true if you can't achieve 85% of your maximum heart rate but don't experience any electrocardiogram (EKG) changes that suggest you're experiencing ischemia. The Duke Treadmill score can be used to determine if a patient is at a low, intermediate or high risk for cardiovascular disease. Positive or abnormal: Doctors may conclude the stress test is positive for cardiac ischemiameaning the heart muscle wasnt getting adequate oxygenated blood during the stress. The Duke treadmill is a popular model and has a score of 8 on the Consumer Reports scale. The resting ECG is usually obtained both supine and standing, since patient position can influence the QRS and T wave axes. The Duke Treadmill score is calculated as follows 6: The angina index has a value of 0 if the patient had no angina during exercise, 1 if the patient had nonlimiting angina, and 2 if angina was the reason the patient stopped exercising.

Intermediate risk (score between 4 and -11) indicates 5-year survival of 90%. Yes, a Duke treadmill score of 7 is good and does not have a high risk for cardiovascular events. 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. ST deviation refers to maximum ST change (elevation or depression) in any lead except lead aVR; and. According to the recommended guidelines for exercise stress testing, elevations in either systolic and/or diastolic blood pressure to 250 and 130 millimetres of mercury are indications to end the test.
