摘　　要：目的探究超声心动图在评估早产新生儿心脏功能及结构中的临床价值。方法回顾性分析2022年2月至2024年2月在漳州正兴医院出生的81例早产新生儿的临床资料,依据胎龄不同分为低胎龄组(≤29周^(+6 d))26例、中胎龄组(30-33周^(+6 d))27例、晚胎龄组(34-36周^(+6 d))28例。三组均应用超声心动图测试,比较三组体重和心率、心脏功能及结构指标,并经Pearson分析心脏功能及结构指标与体重和心率的相关性。结果中胎龄组和晚胎龄组较低胎龄组的体重显著更高,心率显著更低;晚胎龄组较中胎龄组的体重显著更高,心率显著更低(P<0.05)。中胎龄组和晚胎龄组较低胎龄组的左心室射血分数(LVEF)、左心室短轴缩短率(LVFS)、二尖瓣环运动位移(MAPSE)、三尖瓣环运动位移(TAPSE)、二尖瓣舒张早期血流峰值速度(E)/舒张晚期血流峰值速度(A)值显著更高;且晚胎龄组较中胎龄组显著更高(P<0.05)。中胎龄组和晚胎龄组较低胎龄组的左心室舒张末期内径(LVDd)、右心室舒张末期内径(RVDd)、左心室后壁舒张末期厚度(LVPWd)、室间隔舒张末期厚度(IVSd)、舒张末期主动脉根部内径(AOD)、左心房收缩期末期内径(LADs)、左心室收缩末期内径(LVDs)、收缩末期主肺动脉内径(MAP)显著更高;且晚胎龄组较中胎龄组显著更高(P<0.05)。经Pearson分析,早产新生儿的胎龄、体重与LVEF、LVFS、MAPSE、TAPSE、E/A值及LVDd、RVDd、LVPWd、IVSd、AOD、LADs、LVDs、MAP呈正相关性;心率与LVEF、LVFS、MAPSE、TAPSE、E/A值及LVDd、RVDd、LVPWd、IVSd、AOD、LADs、LVDs、MAP呈负相关性(P<0.05)。结论超声心动图能够记录和评估不同胎龄早产儿的心脏功能及结构变化,且早产新生儿的胎龄、体重与心脏功能及结构变化呈正相关性,心率与与心脏功能及结构变化呈负相关性。Objective To investigate the clinical value of echocardiography in assessing the cardiac function and structure of preterm neonates.Methods A retrospective analysis was performed for the clinical data of 81 preterm neonates who were born in Zhangzhou Zhengxing Hospital from February 2022 to February 2024,and according to their gestational age,they were divided into low gestational age group(≤29 weeks^(+6 d)ays)with 26 neonates,moderate gestational age group(30-33 weeks^(+6 d)ays)with 27 neonates,and late gestational age group(34-36 weeks^(+6 d)ays)with 28 neonates.Echocardiography was performed for all three groups,and body weight,heart rate,cardiac function,and cardiac structure were compared between the three groups.The Pearson correlation analysis was used to investigate the correlation of cardiac function and structure indicators with body weight and heart rate.Results Compared with the low gestational age group,the moderate gestational age group and the late gestational age group had a significantly higher body weight and a significantly lower heart rate,and compared with the moderate gestational age group,the late gestational age group had a significantly higher body weight and a significantly lower heart rate(P<0.05).Compared with the low gestational age group,the moderate gestational age group and the late gestational age group had significantly higher values of left ventricular ejection fraction(LVEF),left ventricular fractional shortening(LVFS),mitral annular plane systolic excursion(MAPSE),tricuspid annular plane systolic excursion(TAPSE),and peak diastolic velocity(E)/peak diastolic velocity(A)ratio,and the late gestational age group had significantly higher values than the moderate gestational age group(P<0.05).Compared with the low gestational age group,the moderate gestational age group and the late gestational age group had significantly higher values of left ventricular end-diastolic diameter(LVDd),right ventricular end-diastolic diameter(RVDd),left ventricular posterior wall thickness in diast
