摘　　要：目的 探讨超声斑点追踪技术用于定量评价维持性血液透析患者左心室旋转评估的临床效果。方法 选取2020年8月—2021年12月黑龙江省医院香坊院区行维持性血液透析的54例患者,以及同期在本院行健康体检的54名健康人群为研究对象,分别设为血透组(血透时间<3个月、血透时间≥3个月)、体检组,两组均实施超声斑点追踪技术。比较不同组别心率、左心室收缩末期容积(LVESV)、左心室舒张末期容积(LVEDV)、左心室射血分数(LVEF)、舒张末期室间隔厚度(IVSD)、心尖水平、心底水平。结果 血透组的LVEDV(122.13±20.67)mL、LVESV(58.11±17.65)mL、IVSD(1.23±0.87)cm、LVPWd(1.33±0.23)cm均高于体检组(98.03±17.68)mL、(37.83±12.45)mL、(0.81±0.76)cm、(0.81±0.20)cm,LVEF(52.77±5.46)%低于体检组(62.98±5.76)%,差异有统计学意义(t=6.511、6.900、2.672、12.537、9.453,P<0.05);血透组的前间隔、后间隔、前壁、侧壁、后壁、下壁及整体心尖水平与体检组比较,差异有统计学意义(t=6.110、4.685、4.995、6.462、7.049、5.492、6.516,P<0.05);血透时间<3个月患者的前间隔、后间隔、前壁、侧壁心室旋转角度均大于血透时间≥3个月患者,差异有统计学意义(t=5.099、2.281、3.615、2.162,P<0.05)。结论 超声斑点追踪技术可在维持性血透患者左心室旋转定量评价中发挥显著作用。Objective To explore the clinical effect of ultrasound spot tracking technique for the quantitative evaluation of left ventricular rotation evaluation in patients undergoing maintenance hemodialysis.Methods Fifty-four patients who underwent maintenance hemodialysis in Xiangfang District of Heilongjiang Provincial Hospital from August 2020 to December 2021 and 54 healthy people who underwent physical examination in Heilongjiang Provincial Hospital during the same period were selected as the study subjects,set to hemodialysis group(hemodialysis time<3 months,hemodialysis time≥3 months)and physical examination group respectively.The heart rate,left ventricular endsystolic volume(LVESV),left ventricular end-diastolic volume(LVEDV),left ventricular ejection fraction(LVEF),end-diastolic ventricular septal thickness(IVSD),apical level and cardiac fundus level were compared between the different groups.Results LVEDV(122.13±20.67)mL,LVESV(58.11±17.65)mL,IVSD(1.23±0.87)cm,and LVPWd(1.33±0.23)cm in the hemodialysis group were higher than those in the physical examination group(98.03±17.68)mL,(37.83±12.45)mL,(0.81±0.76)cm,(0.81±0.20)cm,and LVEF(52.77±5.46)%was lower than those in the physical examination group(62.98±5.76)%,the difference was statistically significant(t=6.511,6.900,2.672,12.537,9.453,P<0.05).The levels of anterior septum,posterior septum,anterior wall,lateral wall,posterior wall,inferior wall and overall apex of the heart in the hemodialysis group were compared with those in the physical examination group,the difference was statistically significant(t=6.110,4.685,4.995,6.462,7.049,5.492,6.516,P<0.05).The anterior septal,posterior septal,anterior wall,and lateral wall ventricular rotation angles were higher in patients with<3 months of hemodialysis than in patients with≥3 months of hemodialysis,the difference was statistically significant(t=5.099,2.281,3.615,2.162,P<0.05).Conclusion Ultrasonic speckle tracking technology can play a significant role in quantitative evaluation of left ventricular r
