Methods:Mitral annular early diastole(Ea)and late diastole(Aa)velocities of 30 diabetic patients were measured by DTI and mitral annular inflow velocities E,A were compared with pulse Doppler.

• 方法 :以 DTI技术检测 30例 DM患者二尖瓣环舒张早期运动速度 (Ea)和舒张晚期运动速度 (Aa) ,并用脉冲多普勒法检测二尖瓣舒张早期血流速度 (E)和舒张晚期血流速度 (A) ,比较两组参数的不同。
