Incremental value of 2-dimensional longitudinal radial and circumferential speckle tracking strain imaging to wall motion analysis for detection of coronary artery disease in patients undergoing dobutamine stress echocardiography

ABSTRACT

Background: DSE is considered one of the good options in clinical practice but due to some limitations new promising modalities like speckle tracking echocardiography [STE] was introduced. STE is a new imaging technique that allows evaluation of global and regional myocardial function independently from the angle of acquisition and from cardiac translational movements
