| 目的 应用实时三维超声心动图(RT-3DE)评价酒精性心肌病(ACM)患者右心室收缩功能的变化。方法 对30例ACM患者(ACM组)和30名正常人(对照组)分别进行常规超声及RT-3DE检查。常规超声测量参数包括左心室射血分数(LVEF)、右心室舒张末期面积(RVEDA)和收缩末期面积(RVESA),计算右心室面积变化分数(RVFAC);运用M型超声测量三尖瓣环收缩期位移(TAPSE);RT-3DE测量参数包括右心室舒张末期容积(RVEDV)、收缩末期容积(RVESV)、每搏量(RVSV)、射血分数(RVEF)。比较两组上述参数的差异,分析RVFAC、TAPSE与RVEF的相关性。结果 常规超声中,ACM组RVEDA和RVESA高于对照组,LVEF、RVFAC和TAPSE低于对照组(P均<0.05);RT-3DE中,ACM组RVEDV和RVESV高于对照组,RVEF低于对照组(P均<0.05),两组RVSV无明显差异(P>0.05)。RVFAC、TAPSE均与RVEF呈正相关(r=0.610、0.822,P均<0.05)。结论 RT-3DE能准确评价右心室收缩功能,具有一定临床应用价值。 |

| Objective To evaluate the right ventricular systolic function in patients with alcoholic cardiomyopathy (ACM) by using real-time three-dimensional echocardiography (RT-3DE). Methods Totally 30 patients with ACM (ACM group) and 30 normal subjects (control group) underwent conventional echocardiography and RT-3DE, respectively. Left ventricular ejection fraction (LVEF), right ventricular end-diastolic area (RVEDA) and end-systolic area (RVESA) were measured with echocardiography, and the right ventricular fractional area change (RVFAC) was then calculated. Tricuspid annular plane systolic excursion (TAPSE) was measured by using M-mode echocardiography. Right ventricular end-diastolic volume (RVEDV), end-systolic volume (RVESV), stroke volume (RVSV) and ejection fraction (RVEF) were measured with RT-3DE. The above parameters were compared between ACM and control group, and the correlations of RVFAC, TAPSE and RVEF were analyzed. Results In conventional echocardiography, RVEDA and RVESA were higher, LVEF, RVFAC and TAPSE were lower in ACM group than those in control group (all P<0.05). In RT-3DE, RVEDV and RVESV were higher and RVEF was lower in ACM group than those in control group (all P<0.05), whereas there was no significant difference of RVSV between two groups (P>0.05). RVFAC and TAPSE were both positively correlated with RVEF (r=0.610, 0.822, both P<0.05). Conclusion RT-3DE can be used to assess the right ventricular systolic function accurately, which is valuable on clinical application. |
