<prompt> Which score is calculated during performance of this test?Duke ScoreBruce scoreJones ScoreDeBakey Score  <response>: The image shows a Treadmill test being performed on the patient. Duke treadmill score is used to decide fuher workup and management of patients of chronic stable angina. Duke treadmill score : Maximum exercise time in minutes - 5xST segment detion in mm - 4xangina index Angina index 0 no angina 1 non-limiting angina 2 exercise limiting angina A score 5 indicates low risk for cardiovascular events predicted 4 year survival is 99. A score -11 indicates high risk for cardiovascular events predicted 4 year survival is 79. These patients require fuher investigation with coronary angiography. A score between 4 and -10 indicates intermediate risk. Such patients may require fuher investigation with myocardial perfusion scanning or coronary angiography, or both, depending on the pre-test probability.
