摘要
目的 探讨三维斑点追踪技术(3D-STI)及左室压力-应变环(LV-PSL)评估妊娠期高血压(HDCP)患者左室心肌功能的临床价值。方法 选取我院确诊的HDCP患者33例(HDCP组)和同期正常孕妇32例(对照组),收集两组临床资料;应用常规超声心动图获得舒张末期左室内径、左室后壁厚度(LVPWTd)、室间隔厚度(IVSTd)、二尖瓣口舒张早期及舒张晚期血流速度峰值、二尖瓣环舒张早期运动速度峰值(e’)及Tei指数;应用3D-STI获得左室整体纵向、径向、圆周、面积应变(GLS、GRS、GCS、GAS),以及左室舒张及收缩末期容积指数(EDVI、ESVI)、每搏量指数(SVI)、射血分数、心输出量(CO);应用LV-PSL获得左室心肌整体做功效率(GWE)、整体有用功(GCW)、整体无用功(GWW)、整体做功指数(GWI),比较两组上述参数的差异。结果 (1)临床资料比较:HDCP组体表面积、收缩压、舒张压均较对照组增大,差异均有统计学意义(均P<0.05)。(2)常规超声心动图参数比较:HDCP组IVSTd、LVPWTd均较对照组增厚,e’较对照组减低,Tei指数较对照组增高,差异均有统计学意义(均P<0.05)。(3)3D-STI参数比较:HDCP组GLS、GRS、GCS、GAS均较对照组减低,EDVI、ESVI、SVI、CO均较对照组增高,差异均有统计学意义(均P<0.05)。(4)LV-PSL参数比较:两组GWE、GCW、GWW、GWI比较差异均无统计学意义。结论 应用3D-STI及LV-PSL可准确评估HDCP患者心肌功能,为临床诊治提供参考依据。
Objective To investigate the clinical value of three-dimensional speckle tracking imaging(3D-STI)and left ventricular pressure-strain loop(LV-PSL)in the evaluation of left ventricular myocardial function in patients with hypertensive disorder complicating pregnancy(HDCP).Methods Thirty-three patients with HDCP(HDCP group)and 32 normal pregnant women(control group)in our hospital during the same period were selected.The general data of the two groups were collected.Left ventricular end-diastolic diameter,left ventricular posterior wall thickness(LVPWTd),interventricular septal thickness(IVSTd),mitral valve orifice early diastolic and late diastolic blood flow velocity peaks,mitral ring early diastolic motion velocity peak(e’)and Tei index were obtained by conventional echocardiography.Global longitudinal strain(GLS),global radial strain(GRS),global circumferential strain(GCS),global area strain(GAS),left ventricular end-diastolic volume index(EDVI),left ventricular end-systolic volume index(ESVI),stroke volume index(SVI),ejection fraction,cardiac output(CO)were obtained by 3D-STI.Left ventricular global work efficiency(GWE),global active work(GCW),global wasted work(GWW),global work index(GWI)were obtained by LV-PSL,and the differences of the above parameters between two groups were compared.Results①Comparison of clinical data:the body surface area,systolic blood pressure and diastolic blood pressure in HDCP group were higher than those in control group,and the differences were statistically significant(all P<0.05).②Comparison of conventional echocardiography parameters:IVSTd and LVPWTd in HDCP group were thicker than those in control group,e’was lower than that in control group,and Tei index was higher than that in control group,the differences were statistically significant(all P<0.05).③Comparison of 3D-STI parameters:GLS,GRS,GCS and GAS in HDCP group were lower than those in control group,and EDVI,ESVI,SVI,and CO were higher than those in control group,and the differences were statistically significant(all P<0.05).④Comparison of LV-PSL parameters:there were no significant differences in GWE,GCW,GWW and GWI between HDCP group and control group.Conclusion 3D-STI and LV-PSL can accurately assess the myocardial function in patients with HDCP,and provide reference for clinical diagnosis and treatment.
