Abstract:
Abstract:Objective To evaluate the clinical value of speckle tracking imaging(STI)for the measurement of left ventricular short-axis views regional rotation in patients with heart failure (HF). Methods High frame rate two-dimensional images from the left ventricular short-axis views in 31 patients with CHF(CHF group) and 32 healthy controls(control group) were recorded. The regional rotation(Rot)was measured in the left ventricular short-axis views;the peak endocardium rotation (endo-rot),peak epicardium rotation (epi-rot),peak bulk rotation(bulk-rot),and peak mural torsion(mural-tor) were measured separately. Results Compared with control group,the regional Rot of each segment in patients with CHF was singnificantly decreased(all P<0.01),the peak endo-rot,peak epi-rot,peak bulk-rot,and peak mural-tor were aslo significantly decreased(all P<0.05) in patients with CHF. The left ventricular torsion of patients with CHF was significantly lower than that in control group(P<0.01). Conclusion STI can exactly evaluate the characteristics of left ventricular rotation and the heart function in patients with CHF.
