Value of real-time three-dimensional echocardiography in evaluating overall and segmental left ventricular volume and systolic function

Objective To study the value of real-time three-dimensional echocardiography in evaluating overall and segmental left ventricular volume and systolic function.Methods A total of 40 patients with acute anterior myocardial infarction,50 patients with old myocardial infarction,44 healthy volunteers(control group)were recruited as objects in this study from March 2013 to March 2014.All the objects were performed RT-3DE examination,obtained segmental and overall end-systolic volume(ESV,rESV)through the associated analysis software-time curve.Results The left ventricular end diastolic diameter of acute anterior myocardial infarction,old myocardial infarction patients were significant higher than that of the control group,but the sEF level was significant lower than that of the control group,the differences were all statistical significant(P0.05).The overall left ventricular segmental systolic volume of acute anterior myocardial infarction,old myocardial infarction patients were significant higher than that of the control group.Most of the whole end systolic volume of infarction segments and adjacent infarction area were hither than that of the control group.Conclusion RT-3DE could evaluate overall and segmental left ventricular volume and syst olic function in acute and old myocardial infarction accurately.Reducing of left ventricular total and segmental systolic function would impact on ventricular wall motion synchronicitily.
