Evaluation of regional wall movement abnormalities in coronary artery disease by quantitative tissue velocity imaging / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>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).</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>QTVI is valuable in quantitative and sensitive evaluation of regional wall movement abnormalities for non-invasive diagnosis of CAD.</p>
