Does strain-rate imaging during dobutamine stress echocardiography improve the objective identification of inducible ischemia compared to conventional reading in patients with known or suspected coronary artery disease?
Strain-rate imaging during dobutamine stress echocardiography provides objective quantitative parameters, such as the ratio of postsystolic shortening to maximal strain, which improve the diagnostic accuracy for detecting inducible ischemia.
