摘　　要：目的探讨三维超声斑点追踪技术在定量评估行维持性血液透析治疗慢性肾功能衰竭患者左心室旋转中的应用价值。方法行维持性血液透析治疗慢性肾功能衰竭患者70例为观察组,同期体检健康者70例为对照组,2组行超声心动图检查测量舒张末期室间隔厚度、左心室后壁厚度、左心室舒张末期容积、左心室收缩末期容积及左室射血分数,应用三维超声斑点技术测量心尖及心底水平左心室前间隔、后间隔、前壁、侧壁、后壁、下壁旋转角度。结果观察组舒张末期室间隔厚度、左心室后壁厚度、左心室舒张末期容积、左心室收缩末期容积均较对照组大,左室射血分数较对照组低(P<0.05);观察组旋转角度值在心尖水平左心室前间隔[(6.32±2.01)°]、后间隔[(6.01±1.98)°]、前壁[(6.38±2.12)°]、侧壁[(5.74±2.40)°]、后壁[(4.81±3.01)°]、下壁[(5.34±2.54)°]均小于对照组[(9.51±3.21)°、(9.45±2.87)°、(9.07±3.23)°、(9.36±3.14)°、(9.71±3.28)°、(9.91±3.51)°](P<0.05);在心底水平左心室后壁[(6.53±3.08)°]、下壁旋转角度值[(7.42±3.22)°]均小于对照组[(7.95±3.26)°、(8.71±3.29)°](P<0.05),在心底水平左心室前间隔[(4.23±1.74)°]、后间隔[(6.62±2.32)°]、前壁[(3.25±1.63)°]、侧壁[(4.23±2.41)°]与对照组[(4.12±1.85)°、(6.57±2.05)°、(3.58±2.51)°、(4.62±3.14)°]比较差异均无统计学意义(P>0.05)。结论三维超声斑点追踪技术可清晰显示行维持性血液透析肾功能衰竭患者左心室旋转变化。Objective To explore the value of three-dimensional ultrasound speckle tracking technique to the quantitative evaluation of left ventrieular rotation in patients receiving maintenance hemodialysis. Methods Seventy patients receiving maintenance hemodialysis for chronic renal failure （observation group） and 70 healthy volunteers （control group） received echocardiography to measure end-diastolic interventricular septum thickness, left ventricular posterior wall thickness, left ventricular end-diastolic volume, left ventricular end-systolic volume and left ventricular ejection fraction, and received three-dimensional ultrasound speckle tracking to measure the rotation angles at the apical and basal left ventricular anteroseptum, posterospetum, anterior wall, lateral wall, posterior wall and inferior wall. Results The end-diastolic interventricular septum thickness, left ventricular posterior wall thickness, left ventricular end-diastolic volume and left ventricular end-systolic volume were significantly larger in observation group than those in control group, and left ventricular ejection fraction was significantly lower than that in control group （P〈0.05）. The rotation angle at the apica! left ventricular anteroseptum （（6.32 ± 2.01） ~）, posterospetum （（6.01 ：[： 1.98） ~）, anterior wall （ （6.38 ± 2.12） ~）, lateral wall （（5.74 ＋ 2.40）°）, posterior wall （（4. 81 ~ 3. 01）°） and inferior wall （（5.34 ± 2. 54）°） in observation group were significantly smaller than those in control group （（9.51 ± 3.21）°, （9, 45 ± 2.87）°, （9.07 ± 3.23）°, （9.36 ± 3. 14）°, （9. 71±3.28）°, （9. 91±3.51）°） （P〈0.05）. And the rotation angles at the basal left ventricular posterior wall （（6.53± 3.08）°） and inferior wall （（7. 42±3. 22）°） in observation group were significantly smaller than those in control group （（7.95 ± 3.26）°, （8.71 ± 3.29）°） （P〈0.05）. There were no significant differences i
