摘要
目的应用三维斑点追踪成像(3D-STI)技术评价病毒性心肌炎(VMC)患儿治疗前后左心室心肌整体收缩功能的改变。资料与方法选取38例VMC患儿给予相应治疗,待各项临床指标恢复正常,治疗前后均进行血生化检测及常规超声心动图和3D-STI检查,获得左心室舒张末期内径(LVEDd)、左心室收缩末期内径(LVEDs)、左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)、左心室射血分数(LVEF)、左心室整体纵向应变(GLS)、径向应变(GRS)、圆周应变(GCS)及面积应变(GAS)。结果治疗后心肌肌钙蛋白I及氨基末端B型钠尿肽原水平均低于治疗前,差异有统计学意义(P<0.05)。治疗前、后LVEDd、LVEDs、LVEDV、LVESV、LVEF比较,差异无统计学意义(P>0.05)。治疗后GLS、GRS、GCS、GAS均高于治疗前,差异有统计学意义(P<0.05)。结论 3D-STI技术能够较好地评价VMC患儿左心室心肌功能的异常变化。
Purpose To explore three-dimensional speckle tracking imaging（3 D-STI） in assessing changes of left ventricular global systolic function of viral myocarditis（VMC） child patients before and after treatment. Materials and Methods Thirty-eight VMC child patients were given related treatment and blood biochemistry test, routine ECG and 3 D-STI were taken for examination before and after surgery when the index became normal and results were recorded. Left ventricular end-diastolic diameter（LVEDd）, left ventricular endsystolic diameter（LVEDs）, left ventricular end-diastolic volume（LVEDV）, left ventricular end-systolic volume（LVESV）, left ventricular ejection fraction（LVEF）, global longitudinal strain（GLS）, global radial strain（GRS）, global circumferential strain（GCS） and global area strain（GAS） were obtained. Results Postoperative cardiac troponin I and N-terminal pro-B-type natriuretic peptide levels were all statistically lower than those before surgery（P〈0.05）. Difference of preoperative and postoperative LVEDd, LVEDs, LVEDV, LVESV and LVEF was of no statistical significance（P〉0.05）. Postoperative GLS, GRS, GCS and GAS were statistically higher than those before surgery（P〈0.05）. Conclusion 3 D-STI can evaluate abnormal change of left ventricular myocardial function of VMC child patients.
