[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.


CONCLUSIONS
QTVI is valuable in quantitative and sensitive evaluation of regional wall movement abnormalities for non-invasive diagnosis of CAD.
