ABSTRACT
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 0.05) .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 .
