Implication

Abnormal exercise tests in asymptomatic men warrant cautious interpretation; leaves open optimal diagnostic pathways pending prospective studies.

Key Points

To evaluate the correlation between coronary angiography findings and abnormal electrocardiographic responses to maximal treadmill testing in asymptomatic aircrewmen.
Evaluated 76 asymptomatic male aircrewmen presenting with treadmill exercise testing responses suggestive of coronary artery disease.
Categorized participants into those with normal resting electrocardiograms (n=18) and those with a history of resting repolarization changes (n=58) prior to elective coronary angiography.
Coronary artery disease was angiographically confirmed in 53% (40/76) of asymptomatic men, with many presenting high-risk lesions.
No angiographic evidence of coronary lesions was found in 47% (36/76) of men, who were subsequently recommended for return to flying status without experiencing significant procedural complications.

Structured PICO

What is the prevalence of angiographically demonstrated coronary artery disease in asymptomatic men with abnormal exercise treadmill tests?

Population

76 asymptomatic male aircrewmen with exercise testing responses suggestive of coronary artery disease (18 with normal resting ECGs, 58 with history of repolarization changes on resting ECG)

Intervention

Coronary angiography

Outcome

Angiographically demonstrated coronary artery diseasesurrogate

In asymptomatic aircrewmen with abnormal exercise tests, over half have angiographically proven coronary artery disease, supporting the use of elective coronary angiography in this high-stakes population.
