BACKGROUND
Normal values for regional left ventricular wall motion, although documented in adults, have not been reported in healthy newborns.
METHODS
This study prospectively evaluated global and segmental systolic and diastolic cardiac function by color kinesis in clinically asymptomatic healthy newborns.
RESULTS
Eighty-eight asymptomatic infants who were less than 48 hours old were studied. Systolic and diastolic parameters of global and regional left ventricular function are reported as means +/- SD, medians, 5th and 95th percentiles to establish the normative values for newborns. The reported fractional area changes during systole and diastole are similar to the reported normal values for older subjects. Higher body surface area significantly correlated with an increased peak velocity during systole, and fractional area changes during filling of the lateral wall.
CONCLUSIONS
Our report of left ventricular regional wall-motion characteristics of healthy newborns, as evaluated by color kinesis, may help in the objective evaluation and management of newborns suspected to have global or segmental ventricular dysfunction.
背景
尽管已记录了成人左心室壁节段运动的正常数值，但健康新生儿的相关数值尚未见报道。
方法
本研究采用彩色室壁运动技术对临床无症状的健康新生儿进行前瞻性评估，分析全心和节段性的心脏收缩及舒张功能。
结果
对88例年龄小于48小时的无症状婴儿进行了研究。以平均值±标准差、中位数、第5和第95百分位数报告全心和左心室节段功能的收缩期和舒张期参数，以确立新生儿的正常数值。所报告的收缩期和舒张期面积变化分数与年龄较大受试者的报告正常值相似。较高的体表面积与收缩期峰值速度增加以及侧壁充盈期面积变化分数增加显著相关。
结论
我们通过彩色室壁运动技术评估健康新生儿左心室节段壁运动特征的报告，可能有助于对疑似存在全心或节段性心室功能障碍的新生儿进行客观评估和管理。
