title: Normal coronary angiography in an aircrewman with serial exercise test changes.
abstract: A 45-year-old asymptomatic aircrewman is presented who developed an abnormal ST segment response to maximal treadmill testing after normal responses for 3 previous years. Coronary angiography performed after his abnormal stress test reveled no change from a previously normal study. It has been demostrated that serially performing exercise tests can increase the sensitivity of detecting latent coronary artery disease. The importance of the case report is to demonstrate that the change from a normal exercise test to an abnormal one does not absolutely indicate that an individual has a coronary artery disease and that it is mandatory to search for other possible causes. Further studies will be required to determine the significance of such serial changes.
