Abstract

AIM

To compare different techniques of calculation of left ventricular myocardial mass (LVMM) by one-, two- and three-dimentional echocardiography (EchoCG) and by MRT.

MATERIAL AND METHODS

We calculated LVMM by formulas Penn-cub and modified ASE in one-, two- and three-dimentional EchoCG regimes and MRT; evaluated structural-geometrical characteristics of the left ventricle at various stages of hypertension in 53 hypertensive patients (42 males and 11 females).

RESULTS

Mean LVMM values calculated according to two formulas in one-dimentional regime did not differ significantly but were higher than in two- and three-dimentional regimes. LVMM value according to three-dimentional EchoCG was closer to the results of the summation estimation in MRT.

CONCLUSION

Conventional EchoCG methods of LVMM calculation in M-regime (Penn-cub, ASE) overestimate the results. Most compatible with three-dimentional EchoCG results are those of EchoCG in two-dimentional regime (area-length).

摘要

目的

比较通过一维、二维和三维超声心动图（EchoCG）以及磁共振成像（MRT）计算左心室心肌质量（LVMM）的不同技术。

材料与方法

我们通过一维、二维和三维EchoCG模式以及MRT中的Penn-cub公式和改良ASE公式计算LVMM；评估了53例高血压患者（42例男性和11例女性）在高血压不同阶段左心室的结构几何特征。

结果

在一维模式下根据两个公式计算的平均LVMM值无显著差异，但高于二维和三维模式。三维EchoCG得出的LVMM值更接近MRT的总和估计结果。

结论

M模式下传统的EchoCG计算LVMM的方法（Penn-cub、ASE）高估了结果。与三维EchoCG结果最相符的是二维模式下（面积-长度法）的EchoCG结果。
