| 【】目的 运用超声心动图评价肺动脉高压患者右心室收缩功能。方法 60名肺动脉高压患者按照程度分为三组：轻度组20例,中度组20例,重度组20例,同时选取20名健康成年人作为正常组对照；先用M型超声测量三尖瓣环收缩期位移(TAPSE),二维测量右室面积变化分数 (RVFAC),并用组织多普勒测量三尖瓣环收缩期峰值速度(S’)并计算右室心肌做功指数(RIMP),最后用实时三维超声心动图测量右室舒张末期容积(RVEDV)、右室收缩末期容积(RVESV),计算右室每搏输出量(RVSV)及射血分数(RVEF)。结果 各组间舒张末期容积(RVEDV)差异无统计学意义(P>0.05)；肺高压程度越重,RVESV越大,SV及EVEF值越低,但在中度组和重度组之间的差异不具有统计学意义(P >0.05)。 射血分数(RVEF)与三尖瓣环收缩期位移(TAPSE)、右室面积变化分数 (RVFAC)及三尖瓣环 收缩期峰值速度(S’)呈正相关,与右室做功指数(RIMP)呈负相关。结论 实时三维超声心动图结合M型超声及组织多普勒超声能准确判断肺动脉高压患者右心收缩功能,对临床评价及预后判断有指导意义。 |

| Abstract: |
| 【】Objective To evaluate right ventricular systolic function in patients with pulmonary hypertension(PH) using real-time three-dimensional echocardiography. Methods a total of 60 patients with PH Were enrolled in this study, they were divided into three groups according to pulmonary arterial pressure (PASP) level：mild group and moderate group and severe group, each group consisted of 20 cases, 20 healthy people were enrolled As controls. Firstly, tricuspid annular plane systolic excursion(TAPSE) were measured by M-mode, right ventricular fractional area of change(RVFAC) were measured by 2-DE; Secondly, tissue Doppler-derived tricuspid lateral annular systolic velocity(S’) and calculated right ventricular index of myocardial lperformance(RIMP); In the end, right ventricular end-diastolic volume(RVEDV) and right ventricular end-systolic volume (RVESV) were measured by Real-time Three-dimensional Echocardiography(RT-3DE) and calculated right ventricular stroke volume (RVSV) and right ventricular ejection fraction (RVEF). Results There are no differences of RVEDV among every group(P>0.05), the RVESVs were higher while RVSVs and RVEFs were lower with the increase of the degree of pulmonary arterial hypertention, but it has no different between moderate and severe groups(P>0.05); A positive correlation was found between RVEF and RVFAC、s’、and TAPSE(r=0.658, p=0.000; r=0.832, p=0.000; r=0.886, p=0.000, respectively ), there was a negative correlation between RVEF and RIMP(r=-0.759, p=0.000). Conclusions Real-time three-dimensional echocardiography can assess right ventricular systolic function in patients with PH accurately and provide a guidance for clinical evaluation and prognosis judge. |
