高血压病左室重量指数与血管负荷过重指数的关系

Correlative Analysis of Left Ventricular Mass Index and Vessel Overload Index in Hypertension

目的：探讨左室重量指数（ＬＶＭＩ）及血管负荷过重指数（ＶＯＩ）与高血压病心血管状况的关系。材料和方法：对１０１例心血管病患者中５３例合并高血压病为观察组，４８例未合并高血压病为对照组，４８例未合并高血压病为对照组。用电脑超声诊断仪测量患者心内结构，计算左室重量指数（ＬＶＭＩ），根据血压计算血管负荷过重指数（ＶＯＩ）。结果：两组之间ＬＶＭＩ及ＶＯＩ值相差显著（Ｐ＜０．０５），各组ＬＶＭＩ与ＶＯＩ值呈直线相关（ｒ１＝０．６３９０，ｒ２＝０．７４１１），但两组回归系数（ｂ１，ｂ２）无显著性差异（Ｐ＞０．５），两条回归直线斜率基本相同，即两条回归直线中ＬＶＭＩ对ＶＯＩ的影响规律一致。

Purpose: To define the correation between the LVMI and VOI in hypertension. Materials and Methods: 101 cases with cardiovascular diseases were diveided into two groups, 53 cases with hypertension group i and 48 cases without hypertension group Ⅱ. The intracardiac stracture was charcterized with echocardiography. Left ventricular mass index (LVMI) and vessel overload index (VOI) were determined. Results: There were significant differences in both LVMI and VOI between the tow groups (P<0.05) and in each group linear correlation (P<0.0005) and linear regression (P<0.001) were proved between LVMI and VOI but there was no significant difference between tow regression coefficient (b1,b2. P>0.5). The slope of the regression line in tow groups was identical. Conclusion: Echocardiogrophic determination of LVMI and VOI was useful in reflecting cardiovascular state of the patients suffered from hypertension.
