摘要
目的探讨超声心动图多参数在诊断结核性缩窄性心包炎(CP)中的应用价值。方法选取西安市北方医院2012年4月至2017年4月期间收治的50例结核性CP患者为观察组,另选取同期健康体检者50例为对照组。采用双平面Simpson法测量左心射血分数(LVEF);采用面积法测量右心室舒张末期面积(RVEDA)和右心室收缩末期面积(RVESA),并计算右室面积变化率(RVFAC);二尖瓣口E峰、A峰峰值速度采用脉冲多谱勒测量,并计算E/A;左心室和右心室Tei指数采用组织多普勒成像测量。二尖瓣环收缩期位移(MAPSE)和三尖瓣环收缩期位移(TAPSE)采用M型超声心动图测量,通过QLAB9.1软件CMQ模式分析左室内、外层心肌扭转角度。结果观察组患者的左心室LVEF、E、A和MAPSE分别为(53.89±10.32)%、(69.84±16.33)cm/s、(42.49±14.76)cm/s、(1.02±0.32)cm,明显小于对照组的(61.63±5.02)%、(76.42±10.92)cm/s、(53.37±8.14)cm/s、(1.23±0.13)cm,差异均有统计学意义(P<0.05);观察组患者的左心室E/A和Tei指数分别为(1.64±0.71)和(0.51±0.18),明显大于对照组的(1.43±0.49)和(0.35±0.11),差异均有统计学意义(P<0.05);观察组患者的右心室RVFAC和TAPSE分别为(32.65±17.53)%和(1.31±0.64)cm,明显小于对照组的(46.38±14.79)%和(2.40±0.56)cm,差异均有统计学意义(P<0.05);观察组患者的右心室Tei指数为(0.43±0.15),明显大于对照组的(0.26±0.08),差异有统计学意义(P<0.05);观察组患者的左室内膜、外膜和整体扭转角度分别为(10.91±4.31)°、(4.35±1.21)°和(6.92±2.25)°,明显小于对照组的(15.44±3.22)°、(7.96±2.27)°和(11.17±3.27)°,差异均有统计学意义(P<0.05)。结论超声心动图多参数结合Qlab分析软件可为结核性CP诊断提供更多信息,使诊断结果更为可靠。
Objective To explore the application value of echocardiographic multi-parameter in the diagnosis of tuberculous constrictive pericarditis（CP）. Methods Fifty tuberculous CP patients treated in the Northern Hospital of Xi＇an City from April 2012 to April 2017 were selected as the observation group, and 50 healthy individuals for physical examination at the same time were selected as the control group. The left ventricular ejection fraction（LVEF） was measured by biplane Simpson method. Right ventricular end diastolic area（RVEDA） and right ventricular end systolic area（RVESA） were measured by area method, and the right ventricular area change rate（RVFAC） was calculated. The peak velocity of E peak and A peak of mitral valve were measured by pulse Doppler, and E/A was calculated. The left ventricular and right ventricular Tei indexes were measured by tissue Doppler imaging. The mitral aortic systolic displacement（MAPSE） and tricuspid annulus systolic displacement（TAPSE） were measured by M-mode echocardiography, and the inner and outer myocardial torsion angles of left ventricular were analyzed by QLAB9.1 software CMQ mode. Results The values of LVEF, E, A and MAPSE in the left ventricular were（53.89±10.32）%,（69.84±16.33） cm/s,（42.49±14.76） cm/s and（1.02±0.32） cm in the observation group, which were significantly lower than（61.63±5.02）%,（76.42±10.92） cm/s,（53.37±8.14） cm/s and（1.23±0.13） cm in the control group（P0.05）. The values of E/A and Tei indexes of the left ventricle were（1.64 ± 0.71） and（0.51 ± 0.18） respectively, which were significantly higher than（1.43 ±0.49） and（0.35 ± 0.11） in the control group（P0.05）. The values of RVFAC and TAPSE in the right ventricular were（32.65±17.53）% and（1.31±0.64） cm respectively in the observation group, which were significantly smaller than（46.38±14.79）% and（2.40±0.56） cm in the control group（P0.05）. And the value of right ventricular Tei index was（0.43±0.
