| 目的 评价自然组织谐波成像 (NTHI) 技术在对冠心病左室心内膜的识别和左室整体收缩功能判定方面的应用价值。 方法 对40例冠心病病人(年龄57±9岁)行常规和NTHI二维超声检查。采用心尖四腔、二腔切面,心内膜识别分4级。左室功能测定应用Simpson双平面方法。28例行X线左室造影检测。 结果 NTHI改善了52.5%切面的心内膜识别,提高了左室功能的可检测率 (92.5%对80%),其结果与X线左室造影相关显著,且相关系数高于常规二维超声心动图(r=0.92~0.94对0.86~0.91)。 结论 应用自然组织谐波技术可改善冠心病人心内膜的超声识别,进而增加测定左室收缩功能的可行性和准确性。 |

| Objective To evaluate the effect of the natural tissue harmonic imaging (NTHI) on endocardial border detection and left ventricular global function (LVGF) assessment in patients with coronary artery heart disease (CAD) in comparison with the Results of left ventricular angiography. Methods Ordinary 2D echocardiography (2DE) and NTHI was performed in 40 patients (age 57±9 years) with CAD (32 with myocardial infarction and 8 with angina). Endocardial border definition in apical four-and two-chamber views (AP4CH, and AP2CH) from 1 to 4. LVGF was evaluated by Simpson approach. Results Visualization of endocardial border was improved by 52.5% with NTHI. The EDV, ESV, SV and EF of the left ventricle evaluated by NTHI had better correlation with LV angiographies than those by 2DE. Conclusion NTHI has a significant impact on the endocardial border definition. Thus the LVGF can be evaluated more easily and accurately in the patients with CAD. |
