摘　　要：目的探讨实时三维超声心动图(RT-3DE)评价心肌梗死患者左室收缩功能的准确性。方法选择临床已确诊的心肌梗死患者25例,分别利用二维超声心动图Simpson’s法、RT-3DE全容积法及心脏磁共振成像(CMRI)测量患者左室舒张末容积(LVEDV)、每搏输出量(SV)、左室射血分数(LVEF),并将三种方法所测参数进行对比分析。结果二维超声心动图Simpson’s法与CMRI所测LVEDV、SV比较差异均有统计学意义(均P<0.05),而LVEF差异不明显。RT-3DE与CMRI所测LVEDV、SV、LVEF比较,差异均无统计学意义。Simpson’s法所测LVEDV、SV、LVEF与CMRI所测结果相关(r=0.75、0.75、0.80,P<0.05);RT-3DE全容积法所测LVEDV、SV、LVEF与CMRI所测结果高度相关(r=0.89、0.88、0.91,P<0.05)。结论 RT-3DE可以准确评价心肌梗死患者的左室收缩功能。Objective To explore the accuracy of evaluating left ventricular systolic function using real-time three- dimensional echocardiography（ RT-3DE ） in patients with myocardial infarction. Methods Twenty-five patients with myocardial infarction were selected. Left ventricular end-diastolic volume （LVEDV）, stroke volume （SV） and left ventricular ejection fraction（LVEF） were measured by Simpson＇s method based on 2DE,RT-3DE and CMRI, respectively, and then compared and analyzed. Results There were significant differences in LVEDV and SV between Simpson＇s method based on 2DE and CMRI（P〈0.O5）,while there was no significant difference in LVEF. There were no significant differences in LVEDV, SV and LVEF between RT-3DE and CMRI. LVEDV, SV, LVEF measured by Simpson＇s method correlated with those by CMRI, respectively （r=0.75,0.75,0.80,P〈0.05）. There was a good correlation in LVEDV, SV and LVEF between RT-3DE and CMRI, respectively （r=0.89,0.88,0.91, P〈0.05）. Conclusion RT-3DE can evaluate accurately left ventricular systolic function in patients with myocardial infarction.
