Quantitative approach using multiple single parameters versus visual assessment in dobutamine stress echocardiography.

Background: A number of myocardial Doppler-derived velocity, strain myocardial imaging parameters (DMI) and speckle tracking imaging (STI) have been proposed for the quantification of myocardial ischemia during stress echocardiography. The purpose of the study was to identify the best single ultrasound quantitative parameter for prediction of significant coronary stenosis and compare it with visual assessment during dobutamine stress echocardiography (DSE).

Methods: Prospective analysis included data of 151 patients (age 61.
