Abstract

Various modifications and refinements have been proposed to improve the diagnostic accuracy of standard ST-segment criteria for identifying coronary artery disease using exercise testing. To ascertain if the treadmill exercise score (TES), the ST integral, or the ST/HR index are significantly better markers for coronary disease the standard ST analysis, measured visually or by computer, a retrospective study of 173 male patients was performed. Exclusions were clinical or electrocardiographic evidence of prior myocardial infarction, left ventricular hypertrophy, left bundle branch block, or resting ST segment depression on their baseline electrocardiogram, digitalis, previous revascularization procedure or any significant valvular or congenital heart disease. Ninety-six patients (55.5%) had at least one epicardial coronary stenosis (more than 70% diameter stenosis). Cutpoints were chosen for each method, that maximized their best combination of sensitivity and specificity. There were no statistically significant differences between any of the five methods (TES, ST integral, ST/HR index, standard and computer ST analysis) for identifying any coronary disease. Conclusion: careful visual or ST-segment analysis continues to be the simplest as well most effective marker for coronary disease during exercise testing.
