Regarding METs for a person age 42.5, your output is about 150% of typical sedentary person your age, and about 120% of active person your age. Interpreting exercise treadmill tests needs scoring system. I. undergo a modified Bruce protocol or a manually adjusted protocol. Blood pressure and heart rate are monitored throughout exercise, and the patient is monitored for any developing symptoms such as chest pain, shortness of breath, dizziness or extreme fatigue. A nomogram for practical application of this score is shown in Figure 1 below. Intermediate risk (score between 4 and -11) indicates 5-year survival of 90%. This means that its one of the best treadmills for people who are looking to get an intense workout. Low risk (score > 5) indicates a 5-year survival of 97%. Your email address will not be published.

(4) The total number of minutes of exercise in treadmill testing according to the Bruce protocol (or the equivalent in multiples of resting oxygen consumption [METs] from an alternative protocol) is marked on the exercise-duration line. Another stress test calculation. A normal test is when patients blood pressure and heart rate increase appropriately to graded exercise. A plaque can still cause problems, such as forming clot and blocking arteries. Duke Treadmill Score Requires Bruce Protocol. There is a positive test result when a diagnosis of coronary arteries disease is confirmed.

There is a modified Bruce protocol for those who cannot exercise vigorously, which adds two lower workload stages to the beginning of the standard Bruce protocol, both of which require less effort than Stage 1. Conclusions: Arm exercise scores, analogous to the Duke Treadmill Score, have good power for prediction of mortality or MI in patients who cannot perform leg exercise. This population does not need further investigation with coronary angiography 6. These patients require further investigation with coronary angiography. It is praised for accurate results in both inpatient and outpatient ischemic heart disease populations. Exercise Time - In Minutes - Standard Bruce Protocol. Patients were stratified into risk groups by the treadmill score according to the Duke classification (2). 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. The Duke treadmill score starts at -25 and goes up to +15, with the lowest risk being +15. It was developed to provide diagnostic and prognostic information to help evaluate patients with suspected coronary heart disease. 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. 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].
