Normal coronary angiography in an aircrewman with serial exercise test changes.
Aviation, Space, and Environmental Medicine
|January 1, 1975
Summary
Serial maximal treadmill testing revealed an abnormal ST segment response in an asymptomatic aircrewman, despite previous normal results and unchanged coronary angiography. This highlights that abnormal stress tests do not definitively indicate coronary artery disease, necessitating investigation into other causes.
Area of Science:
- Cardiology
- Exercise Physiology
Background:
- Serial maximal treadmill testing can improve the detection sensitivity of latent coronary artery disease.
- An abnormal stress test response in a patient with previously normal results warrants careful interpretation.
Purpose of the Study:
- To report a case of an asymptomatic aircrewman with a changing treadmill test response.
- To emphasize that an abnormal exercise test does not automatically confirm coronary artery disease.
Main Methods:
- Maximal treadmill testing was performed serially.
- Coronary angiography was conducted for comparison.
Main Results:
- An asymptomatic 45-year-old aircrewman showed an abnormal ST segment response after three years of normal treadmill tests.
- Coronary angiography revealed no changes from a previous normal study.
Conclusions:
- A shift from a normal to an abnormal exercise test response does not definitively diagnose coronary artery disease.
- Further investigation into alternative causes for abnormal stress test results is crucial.
- Additional research is needed to understand the significance of serial changes in exercise test responses.
