Does the inclusion of recovery-only ST-segment depression improve the predictive accuracy of the exercise test for significant angiographic coronary artery disease in male patients?
Including ST-segment depression that occurs only during the recovery phase of exercise testing significantly improves the test's sensitivity for detecting coronary artery disease without reducing its positive predictive value.
