METHODS: In 54 CAD patients (30 of them were confirmed by coronary angiography) systolic velocities of mitral annulus were measured, correlation between DTI and 2D echocardiography findings was also analyzed.

• 方法 :应用 DTI技术 ,对 5 4例临床确诊 (其中 30例经冠脉造影证实 )的冠心病患者收缩期二尖瓣环峰值运动速度 (Sa)进行测定 ,并与二维超声心动图 (2 DE)检查结果对照分析。
