Value of two-dimensional speckle-tracking echocardiography for diagnosing significant coronary stenosis in patients with negative dobutamine stress echocardiography
Background: Detection of regional wall motion abnormalities during dobutamine stress echocardiography (DSE) is challenging and dependent on individual interpretation, which may reduce sensitivity and accuracy while increasing the false-negative rate. Two-dimensional speckle-tracking echocardiography (STE) during DSE is...
