Abstract

BACKGROUND

Echocardiographic assessment of left ventricular mass (LVM) and mass/volume ratio (LVM/V) is an accurate method for evaluating left ventricular hypertrophy. However, reference values for LVM and left ventricular volume (V) in children under 6 years of age have not been well established.

METHODS

Therefore, we evaluated 106 consecutive children (60 males, 46 females, mean age +/- SD 35 +/- 28 months, range 0-72) free of cardiovascular disease by clinical, electrocardiographic and echocardiographic examination. LVM and V were determined by M-mode echocardiography.

RESULTS

The 5th and 95th percentile values of LVM were: 7 and 21 grams for infants aged 0 to 6 months; 13 and 32 grams for 7 to 24 months; 23 and 41 grams for 25 to 36 months; 23 and 59 grams for 37 to 48 months; 30 and 60 grams for 49 and 60 months; 36 and 98 grams for 61 and 72 months. The 5th and 95th percentile values of V were: 4 and 20 ml for infants aged 0 to 6 months; 12 and 36 ml for 7 to 24 months; 16 and 43 ml for 25 to 36 months; 20 to 55 ml for 37 to 48 months; 27 to 64 ml for 49 to 60 months; 39 to 74 ml for 61 to 72 months. The 5th and 95th percentile values of M/V ranged between 1 and 2.3 for infants aged 0 to 6 months, and 0.7-1.2 for those aged 61 to 72 months. LVM, V and LVM/V were significantly (p < 0.0001) related to age, height, weight and body surface area, but were unrelated to gender.

摘要

背景

超声心动图评估左心室质量（LVM）和质量/容积比（LVM/V）是评估左心室肥厚的准确方法。然而，6岁以下儿童的LVM和左心室容积（V）的参考值尚未完全确立。

方法

因此，我们通过临床、心电图和超声心动图检查，对106例无心血管疾病的连续儿童（60例男性，46例女性，平均年龄±标准差35±28个月，范围0 - 72个月）进行了评估。LVM和V通过M型超声心动图测定。

结果

LVM的第5和第95百分位数分别为：0至6个月婴儿为7克和21克；7至24个月为13克和32克；25至36个月为23克和41克；37至48个月为23克和59克；49至60个月为30克和60克；61至72个月为36克和98克。V的第5和第95百分位数分别为：0至6个月婴儿为4毫升和20毫升；7至24个月为12毫升和36毫升；25至36个月为16毫升和43毫升；37至48个月为20至55毫升；49至60个月为27至64毫升；61至72个月为39至74毫升。M/V的第5和第95百分位数在0至6个月婴儿中为1至2.3，在61至72个月婴儿中为0.7 - 1.2。LVM、V和LVM/V与年龄、身高、体重和体表面积显著相关（p < 0.0001），但与性别无关。
