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. Methods
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.
