[Evaluation of Regional Wall Movement Abnormalities in Coronary Artery Disease by Quantitative Tissue Velocity Imaging].

OBJECTIVE:To evaluate the clinical value of quantitative tissue velocity imaging (QTVI) in detection of regional wall movement abnormalities in patients with coronary artery disease (CAD).METHODS:The segmental left ventricular wall motion velocity was measured in 45 normal subjects and 48 patients with CAD, and the parameters of QTVI were analyzed between the two groups.RESULTS:Velocity decrement and wave form alterations were shown in abnormal segmental movements in the CAD group. There were obvious differences in the velocity between normal and abnormal segment.CONCLUSION:QTVI is valuable in quantitative and sensitive evaluation of regional wall movement abnormalities for non-invasive diagnosis of CAD.
