简要总结

The specific aim of this clinical trial is to translate the investigators new 4DE (three sptial dimensions pluse time) stress echocardiographic method to patients with coronary artery disease referred for clinically indicated dobutamine stress/rest echo to evaluate the reproducibility of the technique in this clinical setting.

主要结局

Number of Subjects With an Interpretable 4DE Image

时间窗: After Stress Echocardiography (Approximately 2 hours)

This outcome will measure feasibility. Data from images will be analyzed with the integrated speckle/shape tracking approach (the method uses boundary detection/shape tracking to quantify left ventricular myocardial deformation)
