实时三维超声心动图和二维组织心动图对中青年急性心肌梗死患者左心室功能的评估价值

Evaluation of Left Ventricular Function in Young and Middle-aged Patients with Acute Myocardial Infarction by Real-time Three-dimensional Echocardiography and Two-dimensional Tissue Cardiogram

本文探究了实时三维超声心动图和二维组织心动图对中青年心肌梗死患者左心室功能的评估价值。选取了中青年心肌梗死110例为心肌梗死组,57例无心肌梗死志愿者为对照组,均行二维组织心动图和实时三维超声心动图检查,分析二者对患者左心室功能的评估价值。结果显示,与对照组相比,两种方法检测心肌梗死组患者的LVEF均降低、LVEDV和LVESV均升高(P<0.05);与二维组织心动图相比,两项联合检测的LVEF较低、LVEDV和LVESV较高(P<0.05);与实时三维超声心动图相比,两项联合检测的LVEF较高,LVEDV和LVESV较低(P<0.05);两项联合对中青年心肌梗死心功能分级的诊断准确性高于单项诊断(P<0.05)。综上,实时三维超声心动图联合二维组织心动图可反映出中青年心肌梗死患者的左心室状态,对心功能分级的诊断准确性较高。

The purpose of this research is to explore the value of real-time three-dimensional echocardiography and two-dimensional tissue echocardiography in evaluating left ventricular function in young and middle-aged patients with myocardial infarction.There were 110 young and middle-aged myocardial infarction patients who were selected as myocardial infarction group and 57 volunteers without myocardial infarction who were selected as control group.Two-dimensional histograms and real-time three-dimensional echocardiography were performed to evaluate left ventricular function.The results showed that,compared with the control group,LVEF,LVEDV and LVESV of both echocardiography increased in the myocardial infarction group(P<0.05).Compared with two-dimensional tissue echocardiography,LVEF of real-time three-dimensional echocardiography decreased,while LVEDV and LVESV increased(P<0.05).Compared with real-time three-dimensional echocardiography,LVEF of two-dimensional tissue echocardiography increased,while LVEDV and LVESV decreased(P<0.05).The diagnostic accuracy of the two methods were higher than that of the single diagnosis(P<0.05).In summary,real-time three-dimensional echocardiography combined with two-dimensional tissue cardiogram can reflect the left ventricular state of young and middle-aged myocardial infarction patients.
