Abstract

BACKGROUND

The function of left atrium (LA) is difficult to assess because of its ventricle-dependent, dynamic movement. The aim of this study was to assess LA function using velocity vector imaging (VVI) and compare LA function in patients with hypertrophic cardiomyopathy (HCMP) and left ventricular hypertrophy (LVH) with normal controls.

METHODS

Fourteen patients with HCMP (72% male, mean age of 52.6 ± 9.8), 15 hypertensive patients with LVH (88% male, mean age of 54.0 ± 15.3), and 10 age-matched controls (83% male, mean age of 50.0 ± 4.6) were prospectively studied. Echocardiographic images of the LA were analyzed with VVI, and strain rate (SR) was compared among the 3 groups.

RESULTS

The e' velocity (7.7 ± 1.1; 5.1 ± 0.8; 4.5 ± 1.3 cm/sec, p = 0.013), E/e' (6.8 ± 1.6; 12.4 ± 3.3; 14.7 ± 4.2, p = 0.035), and late diastolic SR at mid LA (-1.65 ± 0.51; -0.97 ± 0.55; -0.82 ± 0.32, p = 0.002) were significantly different among the groups (normal; LVH; HCMP, respectively). The e' velocity, E/e', and late diastolic SR at mid LA were significantly different between normal and LVH (p = 0.001; 0.022; 0.018), whereas LA size was similar between normal and LVH (p = 0.592). The mean late diastolic peak SR of mid LA was significantly correlated with indices of diastolic function (E/e', e', and LA size).

CONCLUSIONS

The SR is a useful tool for detailed evaluation of LA function, especially early dysfunction of LA in groups with normal LA size.

摘要

背景

由于左心房（LA）依赖心室且运动动态，其功能难以评估。本研究旨在使用速度向量成像（VVI）评估LA功能，并比较肥厚型心肌病（HCMP）和左心室肥厚（LVH）患者与正常对照者的LA功能。

方法

前瞻性研究了14例HCMP患者（男性占72%，平均年龄52.6±9.8岁）、15例LVH高血压患者（男性占88%，平均年龄54.0±15.3岁）和10例年龄匹配的对照者（男性占83%，平均年龄50.0±4.6岁）。使用VVI分析LA的超声心动图图像，并比较三组之间的应变率（SR）。

结果

三组之间的e'速度（7.7±1.1；5.1±0.8；4.5±1.3 cm/秒，p = 0.013）、E/e'（6.8±1.6；12.4±3.3；14.7±4.2，p = 0.035）和LA中部舒张晚期SR（-1.65±0.51；-0.9
