Abstract:
ObjectiveTo evaluate left ventricular systolic synchrony in patients with coronary artery disease (CAD) by speckle tracking imaging (STI) and real-time three-dimensional echocardiography (RT3DE) and investigate the correlation with ECG-gated myocardial perfusion single-photon emission computed tomography (GMPS).MethodsA total of thirteen patients with CAD diagnosed by coronary angiography underwent STI and RT-3DE examinations.The data was analysed off-line using Qlab 8.0 software.STI systolic synchrony indexes included the standard deviation of times to peak strain in radial and circumferial direction in 12 left ventricular segments (Trs12-SD and Tcs12-SD),the standard deviation of times to peak longitudinal strain in 16 left ventricular segments (Tls16-SD).RT-3DE systolic synchrony indexes included the standard deviation of times to the minimum systolic volume in 16 and 12 left ventricular segments (Tmsv16-SD and Tmsv12-SD).GMPS was performed within one week before or after echocardiography.Phase analysis was performed offline using Emory Cardiac Toolbox software.Peak phase,phase SD,bandwidth,skewness and kurtosis were calculated.Results Trs12-SD derived from STI had a positive correlation with phase SD and bandwidth ( r =0.800,P ＜0.05 ; r =0.607,P ＜0.05).Tmsv16-SD derived from RT-3DE had a better positive correlation with phase SD and bandwidth ( r =0.847,P =0.001 ; r =0.890,P ＜0.001).ConclusionsTmsv16-SD derived from RT-3DE had a better correlation with GMPS parameters than STI parameters.RT-3DE assessment of left ventricular systolic parameters is expected to become the ideal synchronization indicator.
