Application of Real-time Three-Dimensional Echocardiography in the Evaluation of Left Ventricular Systolic Function in Patients with Myocardial Infarction
摘要
Abstract
Objective To study the accuracy of the real-time three-dimensional echocardiography (RT-3DE) in evaluating left ventricular systolic function in patients with myocardial infarction. Meth-ods 48 cases that were clinically diagnosed of left ventricular infarction were divided into 4 groups based on infarction sites: inferior wall (n = 11), posterior wall (n = 13), anterior and anteroseptal wall (n=12), and lateral wall (n=12). By using the methods of two-dimensional echocardiography (2DE) Simpson, RT-3DE and magnetic resonance imaging (CMRI), each cases was measured in categories of left ventricle diastolic volume (LVEDV), stoke volume (SV), and left ventricular ejection fraction (LVEF); parameters obtained from the former two methods were analyzed in comparison with which obtained from CMRI. Results There was statistically significant difference in group 1, 3, and 4 in LVEDV and SV (P<0.05); there was no statistically significant difference in group 1, 3, and 4 in LVEF by using 2DE Simpson and CMRI (P>0.05). The cases of group 2 all showed statistically significant difference in LVEDV, SV, and LVEF by using 2DE Simpson and CMRI (P<0.05). There was no statistically significant difference in all four groups in LVEDV, SV and LVEF by using RT-3DE and CMRI (P>0.05). LVEDV, SV, LVEF measured by Simpson method correlated with the results obtained from CMRI respectively. There was good correlation between LVEDV, SV, and LVEF from RT-3DE and those from CMRI respectively. Conclusion It was proved that left ventricular systolic function could be evaluated accurately by RT-3DE, which might provide a reliable way to appraise cardiac function in patients with myocardial infarction. This would compensate for the low accuracy of Simpson method so that measurement of left ventricular systolic function in patients with left ventricular posterior wall myocardial infarction could be more accurate. RT-3DE is worthy of clinical promotion.关键词
