摘要

背景:支气管肺发育不良(BPD)可导致慢性肺动脉高压和右心室功能障碍。各种右心室功能障碍的超声心动图评估已被用于确定超声心动图测量BPD早产儿是否可以提供与BPD严重程度相关的右心室功能的敏感测量。方法28例无BPD对照组(非BPD组)、28例轻度BPD患者、11例中度BPD患者和6例重度BPD患者行m型射血分数、三尖瓣反流压力梯度、脉冲多普勒心肌功能指数(MPI)和组织多普勒成像(TDI)等标准测量的超声心动图。采用NICHD/NHLBI/ORD车间评定量表对BPD的严重程度进行分类。28例无BPD的对照组(非BPD组)、28例轻度BPD患者、11例中度BPD患者和6例重度BPD患者行超声心动图检查,标准测量指标包括m型射血分数、三尖瓣反流压力梯度、脉冲多普勒心肌功能指数(MPI)和TDI测量。采用NICHD/NHLBI/ORD车间评定量表对BPD的严重程度进行分类。结果对照组与BPD组超声心动图各项指标无明显差异。重度BPD组平均间隔TDI-MPI(0.68±0.06)明显高于非BPD组(0.58±0.10)和轻度BPD组(0.59±0.12),差异有统计学意义(p < 0.01)。重度BPD组RV TDI-MPI平均值(0.71±0.13)显著高于非BPD组(0.56±0.08)或轻度BPD组(0.60±0.125),差异有统计学意义(p < 0.05)。线性回归显示BPD的严重程度与RV TDI-MPI (p = 0.01, R = 0.30)或间隔TDI-MPI (p = 0.04, R = 0.24)有良好的相关性。结论基于右心室TDI-MPI的超声心动图评价右心室功能可为BPD早产儿右心室功能障碍提供参数。

Clinical Utility of Echocardiography for the Diagnosis and Prognosis in Children with Bronchopulmonary Dsyplasia
Background Bronchopulmonary dysplasia (BPD) may result in chronic pulmonary artery hypertension and right ventricular (RV) dysfunction. Various echocardiographic assessments of RV dysfunction have been used to determine whether echocardiographic measurements of premature infants with BPD could provide sensitive measures of RV function that correlates with BPD severity. Methods Twenty-eight control subjects without BPD (non BPD group), 28 patients with mild BPD, 11 patients with moderate BPD, and six patients with severe BPD underwent echocardiograms with standard measurement such as ejection fraction by M-mode, tricuspid regurgitation pressure gradient, myocardial performance index (MPI) derived from pulse Doppler, and tissue Doppler imaging (TDI) measurements. BPD severity was classified by the NICHD/NHLBI/ORD workshop rating scale. Twenty-eight control subjects without BPD (non BPD group), 28 patients with mild BPD, 11 patients with moderate BPD, and six patients with severe BPD underwent echocardiograms with standard measurement such as ejection fraction by M-mode, tricuspid regurgitation pressure gradient, myocardial performance index (MPI) derived from pulse Doppler, and TDI measurements. BPD severity was classified by the NICHD/NHLBI/ORD workshop rating scale. Results None of the standard echocardiographic findings was significantly different between the control group and BPD groups. However, mean septal TDI-MPI of the severe BPD group (0.68 ± 0.06) was significantly (p < 0.01) higher than that of the non-BPD (0.58 ± 0.10) or the mild BPD group (0.59 ± 0.12). In addition, mean RV TDI-MPI of the severe BPD group (0.71 ± 0.13) was significantly (p < 0.05) higher than that of the non-BPD group (0.56 ± 0.08) or the mild BPD group (0.60 ± 0.125). Linear regression showed a good correlation between the severity of BPD and RV TDI-MPI (p = 0.01, R = 0.30) or septal TDI-MPI (p = 0.04, R = 0.24). Conclusion Echocardiographic evaluation of RV function based on an assessment of RV TDI-MPI can provide RV dysfunction parameter in premature infants with BPD.
