Sensitivity and specificity of strain and strain rate imaging [measured by speckle tracking] in assessment of ischemic heart disease compared to dobutamine stress echocardiography

ABSTRACT

Background: speckle tracking echocardiography [STE] enables objective assessment of left ventricular [LV] function through analysis of myocardial strain and strain rate. This study aims to determine the sensitivity and specificity of global longitudinal strain [GLS] and global longitudinal strain rate [GLSR] of LV in assessment of myocardial Jirnction compared to peak wall motion score index [WMSI] at dobutamine stress echocardiography [DSE]
