[Evaluation of regional wall movement abnormalities in coronary artery disease by quantitative tissue velocity imaging].

ABSTRACT

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.
