In patients suspected of having coronary artery disease (CAD), we compared the diagnostic sensitivity and specificity of exercise testing using ST-segment changes alone and ST-segment changes, angina pectoris, and hemodynamic variables compared to coronary computed tomographic angiography (CTA). Quantitative invasive coronary angiography was the reference method (>50% coronary lumen reduction). A positive exercise test was defined as the development of significant ST-segment changes (≥1 mV measured 80 ms from the J-point), and the occurrence of one or more of the following criteria: ST-segment changes ≥1 mV measured 80 ms from the J-point, angina pectoris, ventricular arrhythmia (the occurrence of ≥3…
