摘要
目的探讨斑点追踪技术(STI)评价不同孕期妊高症(PIH)患者心功能改变的临床价值。方法选择2014年7月~2015年6月我院收治的62例PIH患者作为观察组,另选择同期例行健康孕检的62例孕妇作为对照组。采集两组的左室心底水平(MV)、心尖水平(AP)二维图像,并以STI对所获取的图像进行分析,比较两组不同孕期的旋转角度、扭转角度等参数。结果观察组孕早、中期的扭转角度峰值(Ptw)、心尖程度旋转角度峰值(Prot-AP)值大于对照组,差异有统计学意义(P<0.05);与早期妊娠组相比,观察组和对照组孕中期的Ptw、Prot-AP值增大,晚期Prot-AP值减小,差异有统计学意义(P<0.05);与妊娠中期相比,两组孕晚期的Ptw值增大,差异有统计学意义(P<0.05);两组各期的心底水平旋转角度峰值(Prot-MV)、心底水平旋转角度达峰绝对时间(Pti-MV)比较,差异无统计学意义(P>0.05);观察组孕早、中、晚期的达峰时间百分比(Perc-Pti-AP)及晚期峰时间百分比(Perc-PtiMV)、心尖水平旋转角达峰绝对时间(Pti-AP)均大于对照组,差异有统计学意义(P<0.05)。结论对PIH患者早期实施STI技术可有效观测患者左心室扭转及旋转运动,利于早期评价PIH患者心功能。
Objective To investigate the clinical value of speckle tracking imaging （STI） in evaluation of changes of car- diac function in pregnancy-induced hypertension （PIH） patients in different pregnancy phase.Methods 62 PIH patients in our hospital from July 2014 to June 2016 were selected as the observation group,and 62 pregnant women with preg- nancy examination were selected as the control group at the same time.The imaging of left ventricular cardiac base （MV） level,apex （AP） level of two groups were collected,and which was analyzed by STI.The rotation angle,twist angle of the two groups in different pregnancy phase were compared.Results The peak value of twist angle （Ptw）,peak apical rotation angle （Prot-AP） of the observation group in early,mid-pregnancy phase were larger than those of the control group,with significant difference （P〈0.05）.Compared with early pregnancy phase,the Ptw,Prot-AP value of the observation group and the control group in mid-pregnancy increased,and the Prot-AP value in late phase decreased,with significant difference （P〈 0.05）.Compared with mid-pregnancy phase,the Ptw value of late pregnancy phase in the two groups increased,with sig nificant difference （P〈O.OS）.There was no significant differencein the peak rotation-MV （Prot-MV）,peak time-MV （Pti-MV） levels in the each phase between the two groups （P〉3.05）.The percent of peak time-MV （Perc-Pti-MV） in early pregnancy,mid-pregnancy,late pregnancy,Perc-Pti-MV,Pti-AP in late pregnancy phase of the observation group were larger than those of the control group,with significant difference （P〈0.05）.Conclusion The early application of STI in PIH patients can effec- tively observe left ventricular torsion and rotation motion,facilitate early evaluation of cardiac function of PIH patients.
