三维超声心动图对老年持续性心房颤动患者心脏结构和心室功能的评估价值

Evaluation of three-dimensional echocardiography in evaluating cardiac structure and ventricular function in elderly patients with persistent atrial fibrillation

目的探讨三维超声心动图对老年持续性心房颤动患者心脏结构和心室功能的评估价值。方法选取2015年7月至2017年12月于安阳市第三人民医院超声科进行检查的61例老年持续性心房颤动患者为研究对象,另选同期我院健康体检中心的60名健康志愿者为对照组。对两组受试者分别进行常规超声和三维超声心动图检查,测量两组受试者的左、右心房,左、右心室的超声指标,并进行组间比较。结果常规超声检查显示,两组患者的心房和心室结构功能指标[左心室舒张末期内径(LVDd)、左心室收缩末期内径(LVDs)、室间隔厚度(IVSTd)、左心室后壁厚度(LVPWd)、左心房舒张末期面积(LAA)、右心房舒张末期面积(RAA)、二尖瓣反流(MR)、三尖瓣反流(TR)]比较,差异均无统计学意义(P均>0.05)。三维超声心动图检查显示,观察组患者的右心室舒张末期最大容积(RVEDV)、右心室收缩末期最小容积(RVESV)、左心室舒张末期最大容积(LVEDV)、左心室收缩末期最小容积(LVESV)均大于对照组,右心室射血分数(RVEF)、左心室射血分数(LVEF)均低于对照组,组间比较差异均有统计学意义(P均<0.05)。结论三维超声心动图能够准确的测量和评估老年持续性心房颤动患者的心脏结构和心室功能,对此类患者的临床诊断有重要的应用价值。

Objective To evaluate the value of three-dimensional echocardiography in evaluating cardiac structure and ventricular function in elderly patients with persistent atrial fibrillation.Methods A total of 61 elderly patients with persistent atrial fibrillation who underwent examination in the Department of Ultrasound,Third People's Hospital of Anyang from July 2015 to December 2017 were selected as observation groups.In the same period,60 healthy volunteers from our Health Checkup Center were selected as the control group.Routine ultrasound and three-dimensional echocardiography were performed on the two groups,and the ultrasound indexes of the left and right atrium,left and right ventricles of the two groups were measured,and comparison between groups was performed.Results Conventional ultrasonography showed that there was no significant difference in atrial and ventricular structural and functional indexes[left ventricular end diastolic diameter(LVDd),left ventricular end systolic diameter(LVDs),interventricular septum thickness(IVSTd),left ventricular posterior wall thickness(LVPWd),left atrium end-diastolic area(LAA),and right atrium diastolic end.There was no significant difference in area(RAA),mitral regurgitation(MR)and three cusp regurgitation(TR)]between the two groups(P>0.05).Threedimensional echocardiography showed that right ventricular end diastolic maximum volume(RVEDV),minimum volume of right ventricular end systolic(RVESV),maximum left ventricular end diastolic volume(LVEDV)and minimum volume of left ventricular end systolic volume(LVESV)in the observation group was larger than those in the control group.The right ventricular ejection fraction(RVEF)and left ventricular ejection fraction(LVEF)was lower than those of the control group,and there were significant differences between the two groups(P<0.05).Conclusions Three-dimensional echocardiography can accurately measure and evaluate the cardiac structure and ventricular function of elderly patients with persistent atrial fibrillation,which has important application value for clinical diagnosis of such patients.
