摘　　要：目的 探讨实时三维超声斑点追踪成像(3D-STI)在冠心病诊断中的应用价值。方法 选取2018年1月至2019年3月在郑州市第七人民医院治疗的冠心病病人110例(冠心病组),采用冠状动脉(冠脉)病变评分(Gensini评分)标准进行评分,其中轻度病人32例,中度病人56例,重度病人22例,同时选取健康志愿者110例作为对照组,给予3D-STI检查。结果 冠心病组左室整体长轴应变(GLS)、左室整体轴向应变(GCS)和左室整体面积应变(GAS)分别为(-14.48±2.19)%、(-16.68±2.11)%和(-27.81±3.02)%,明显低于对照组的(-11.21±2.24)%、(-15.03±2.09)%和(-26.49±2.48)%,P<0.05。冠心病组和对照组左室整体径向应变(GRS)比较差异无统计学意义(P>0.05)。重度病人GLS、GCS和GAS分别为(-17.53±3.00)%、(-18.72±2.99)%和(-29.82±3.00)%,明显低于轻度病人的(-13.57±2.21)%、(-16.12±2.81)%和(-27.25±2.80)%和中度病人的(-13.80±2.71)%、(-16.22±2.73)%和(-27.34±2.91)%(P<0.05)。GLS和GCS诊断冠心病ROC曲线下面积分别为0.847和0.726,P<0.05,截断值分别为-13.10和-16.50,灵敏性分别为80.50%和67.50%,特异性分别为70.00%和60.00%。结论 3D-STI在冠心病诊断中有较好的应用价值,其相关参数可一定程度反映病人病情程度。Objective To explore the value of real-time three-dimensional ultrasound speckle tracking imaging (3D-STI) in the diagnosis of coronary heart disease.Methods One hundred and ten patients with coronary heart disease (CHD group) who were treated in the Seventh People’s Hospital of Zhengzhou from January 2018 to March 2019 were selected,Gensini score was used for scoring,among which 32 patients were mild,56 patients were moderate,and 22 patients were severe,and 110 healthy volunteers were selected as control group,and were examined by 3D-STI.Results Left ventricular global long axis strain (GLS),left ventricular global axial strain (GCS) and left ventricular global area strain (GAS) in CHD group were (-14.48±2.19)%,(-16.68±2.11)%and (-27.81±3.02)%,which were significantly lower than those in control group[(-11.21±2.24)%,(-15.03±2.09)%,(-26.49±2.48)%,P<0.05].There was no significant difference in global left ventricular radial strain (GRS) between CHD group and control group (P>0.05).GLS,GCS and GAS in severe patients were (-17.53±3.00)%,(-18.72±2.99)%and (-29.82±3.00)%,which were significantly lower than those of mild patients[(-13.57±2.21)%,(-16.12±2.81)%,(-27.25±2.80)%],which were significantly lower than those of moderate patients[(-13.80±2.71)%,(-16.22±2.73)%,(-27.34±2.91)%,P<0.05].The area under ROC curve of GLS and GCS for diagnosis of coronary heart disease was 0.847 and 0.726,P<0.05,the cut-off values were-13.10 and-16.50,the sensitivity were 80.50%and 67.50%,and the specificity were 70.00%and 60.00%,respectively.Conclusion 3D-STI has a good application value in the diagnosis of coronary heart disease,and its related parameters can reflect the severity of patients to a certain extent.
