目的：应用二尖瓣环自动追踪技术（AMAT）定量检测慢性肾功能衰竭（CRF）患者二尖瓣环运动参数，评价左心室收缩功能。方法尿毒症组18例，非尿毒症组16例，正常对照组22例，取心尖四腔心切面，运用 AMAT 技术测量二尖瓣环左室间隔侧、侧壁纵向位移（Y-Posi L、Y-Posi R）、横向位移（X-Posi L、X-Posi R）等参数，并进行统计分析。结果与对照组比较，尿毒症组左心室舒张末期容积（LVEDV）、收缩末期容积（LVESV）、射血分数（LVEF）显著降低，X-Posi L、Y-Posi L 显著降低，非尿毒症组 X-Posi L 亦显著降低。纳入病例 X-Posi L、Y-Posi L 与 LVEF 均呈显著正相关（r 分别为0.67、0.71，P ＜0.05）。结论AMAT 可以评价CRF 患者患者左心室收缩功能。

Objective To explore the value of mitral annular displace based on AMAT in evaluating left ventricular function in pa-tients with chronic renal failure.Methods There were 34 chronic renal failure cases in groups(uremia group 18 cases,non-uremia group 16 cases),and 22 cases in normal control group.Apical four chamber view was acquired,and AMAT was used to measure left ventricular septal and lateral wall mitral annular longitudinal and horizontal displacement(Y-Posi L,Y-Posi R,X-Posi L,X-Posi R),then statistical analysis was performed.Results Compared with the control group,LVEDV,LVESV,LVEF decreased significantly in uremia group,X-Posi L,Y-Posi L al-so decreased significantly.X-Posi L decreased significantly in non-uremia group.X-Posi L,Y-Posi L were positively correlated with LVEF in all cases(r =0.67,0.71,P <0.05).Conclusion AMAT can evaluate the left ventricular systolic function in patients with chronic renal failure.
