Abstract:
Objective To assess the left ventricular longitudinal shrinkage function in liver cirrhosis patients with two-dimensional speckle tracking imaging (2D-STI). Methods Echocardiography and Doppler echocardiography were performed in 34 patients with liver cirrhosis and 35 healthy subjects of corresponding ages. High frame rate two-dimensional images were recorded from apical long-axis view, four-chamber view and two-chamber view of left ventricle; then the left ventricular diameter, left atrium diameter, the peak filling velocity of E wave and A wave, E/A ratio, EF and FS were measured. The peak systolic strain of left ventricular segment was measured with two-dimensional strain software. Results Compared with healthy subjects, left ventricular diameter, left atrium diameter, EF and FS of liver cirrhosis patients were not statistically different (P>0.05), but the E/A ratio was lower (P<0.05). The peak systolic strain of most left ventricular segment in liver cirrhosis reduced significantly (P<0.05), except that of base segment of posterior wall, anterior wall, inferior wall, anterior and posterior interventricular septum, as well as middle segment of posterior interventricular septum. Conclusion The heart shape, systolic and diastole function of liver cirrhosis are abnormal. 2D-STI can early and accurately evaluate the systolic function of liver cirrhosis.
