摘　　要：目的探讨实时三维超声心动图(RT3DE)检测急性前壁心肌梗死患者整体和节段心功能的临床价值。方法运用RT3DE对20例急性前壁心肌梗死患者和41例正常人进行检查,脱机软件分析得出左室整体和17节段的容积-时间曲线,比较两组的整体和节段舒张末期容积(EDV、rEDV)、收缩末期容积(ESV、rESV)、射血分数(EF、rEF)及节段-整体射血分数(rgEF)。结果急性前壁心梗组整体EDV、ESV及梗死区域、邻近梗死区域的rEDV、rESV较对照组增大,整体EF值及其rEF、rgEF减小(P<0.05),远离梗死区域无差异(P>0.05)。结论RT3DE能客观评价急性前壁心梗患者左室整体和节段心功能,是一项能运用于临床的准确、可行的新技术。Objective To evaluate clinical use of real-time three-dimensional echocardiography in analyzing global and reglonal left ventricular function in patients with acute anterior myocardial infarction. Methods The study consisted of 41 normal subjects and 20 patients with acute anterior myocardial infarction. RT3DE was performed and three-dlmensional image data was analyzed offline with software. A series of global and regional left ventricular volume curves were plotted. Global and regional diastolic volumes, systolic volumes, and ejection fractions, and regional stroke volume to global diastolic volume （rgEF） were compared respectively between the two groups. Results Compared with control group, global diastolic volume and systolic volume in the patients were larger （P〈0.05）, while eiection fraction was lower （P〈0.05）. The regional volumes were larger and regional ejection fraction and rgEF were lower in the zones with infarction （P〈0.05）. No significant statistic change was found in the distal zones of infarction （P〉0.05）. Conclusion RT3DE emerges as a new technology for clinical use, because it allows accurate, rapid, and feasible measurement of left ventricular function in patients with acute anterior myocardial infarction.
