Studies corrected for referral bias show a sensitivity of 45-88% and a specificity of 59-91%. The advantages of MPI over exercise stress testing are better sensitivity and specificity in the presence of inadequate workload, ability to localize area of ischemia, and the ability to detect graft closure. In each type of study, the myocardium can be stressed by either exercise or chemicals. Myocardial imaging studies are either MPI using either thallium (201T1) or technitium (99mTc) or stress echocardiography. However,all of these benefits come at a greatly increased cost. transmural) and allows evaluation of ischemia in the presence of an abnormal resting ECG. Imaging techniques enhance the information gained from exercise testing reduce the false-positive rate seen with exercise testing, which provides a better positive predictive value for risk stratification allows for the identification of area of ischemia (subendocardial vs. Combining clinical information with test data yields a 94% sensitivity and 92%specificity. 3 The predictive value of the exercise stress test is greatest when test results are combined with family history, current symptoms, and underlying risk factors( Table 1). Exercise stress testing is presently used to assess physical fitness, determine functional capacity,diagnose cardiac disease, define the prognosis of known cardiac disease,prescribe an exercise plan, and guide cardiac rehabilitation. 2 identified four major clinical uses of exercise testing relating to diagnosis, prognosis,functional assessment, and therapeutic prescription. Electrocardiograph (ECG) exercise stress testing is a reliable and widely used method of evaluating patients who have or are at risk of developing cardiovascular disease. One of the diagnostic tools for the diagnosis and risk stratification of coronary heart disease is exercise treadmill testing, whose diagnostic and prognostic value has been studied extensively. There are no evidence-based guidelines for screening asymptomatic diabetic patients for CAD.
