title: The detection of asympatomatic coronary artery disease.
abstract: In summary, near-maximal or maximal exercise testing has a sensitivity of approximately 60% and a specificity of approximately 90% for coronary atherosclerotic heart disease. When screening asympatomatic men with exercise testing, an abnormal response identifies a group of men at very high risk for coronary artery disease. However, the predictive value limitations are obvious and the false-positive problem must be realized. At present, there is no second line of noninvasive studies that can separate an exercise-test false positive from a true positive with certainty. Risk-factor consideration may help separate them; The sensitivity limitations of exercise testing must be especially considered when evaluating people at high risk for CAD. An abnormal test response does not absolutely predict the presence of CAD and a normal response does not rule out its possibility. In appropriate instances where coronary angiography can be performed at minimal risk and when it is justified for reasons of public safety or individual well-being, this procedure can give a reasonably definitive answer. Creation of iatrogenic "cardiac cripples" can be the most common complication of screening tests and should be avoided. Therefore, good clinical judgment needs to be used in conjunction with any screening test.
