目的:探讨脉冲多普勒(PW)及组织同步成像技术(TSI)评价缺血性心肌病(ICM)患者心脏收缩的同步性的价值。方法:搜集ICM患者50例(ICM组),无器质性心脏病健康志愿者35例(健康对照组),分别用PW测量二尖瓣舒张期血流持续时间/RR间期(LVFT/RR )来评价左房、左室同步性;测量心室间机械延迟时间(IVMD)来评价左右室间同步性;用TSI软件测量二尖瓣环平均收缩峰速度(LV-Sm),收缩期达峰时间(Ts)及所有节段收缩期达峰时间的标准差(Ts-SD )来评价左室内收缩的同步性。结果:与健康对照组比较, ICM组LVFT/RR [(44.74±1.58)%比(41.08±4.65)%]、LV-Sm [(9.72±0.53) ms比(4.09±1.06) ms]显著降低, IVMD [(15.51±5.52) ms比(41.96±4.20) ms]、Ts-SD [(16.47±4.16) ms比(34.13±11.68) ms]显著增加, P均<0.01;前壁、下壁等6部位的Ts显著延长,且同步性显著降低;左室内收缩最延迟部位所占比例无显著差异(P>0.05)。结论:缺血性心肌病患者较健康对照组左室整体收缩功能明显减低,左房、左室,左右室间,左室内收缩同步性明显降低。

Objective:To explore value of pulsed wave (PW) and tissue synchronization imaging (TSI) evaluate cardi-ac systolic synchronization in patients with ischemic cardiomyopathy (ICM) .Methods:A total of 50 ICM patients were enrolled as ICM group and 35 healthy volunteers without organic heart disease were regarded as healthy control group ,PW was used to measure mitral diastolic blood flow duration/RR interval (LVFT/RR) to evaluate synchroni-zation of left atrial and left ventricular synchronization ;interventricular mechanical delay (IVMD) was measured to evaluate left and right ventricular synchronization ;TSI software was used to measure mitral annular mean systolic peak velocity (LV-Sm) ,systolic time to peak (Ts) and Ts standard deviation (Ts-SD) of all segments in order to e-valuate left ventricular systolic synchronization .Results:Compared with healthy control group ,there were signifi-cant reductions in LVFT/RR [ (44.74 ± 1.58)% vs .(41.08 ± 4.65)% ] and LV-Sm [ (9.72 ± 0.53) ms vs .(4.09 ± 1.06) ms] ,and significant rise in IVMD [ (15.51 ± 5.52) ms vs .(41.96 ± 4.20) ms] and Ts-SD [ (16.47 ± 4.16) ms vs .(34.13 ± 11.68) ms] in ICM group , P<0.01 all;Ts of anterior wall ,inferior wall et .6 positions were significantly longer ,and its synchronization significantly reduced , P<0. 05 all ,percentages of the most de-layed systolic part of left ventricle were no significant differences between two groups (P> 0.05) .Conclusion:Compared with healthy control group ,left ventricular total systolic function ,left atrial&ventricular ,left&right ventricular synchronization and systolic synchronization within left ventricular significantly reduce in ICM patients .
