Abstract:

Abstract:Objective To evaluate the regional left ventricular systolic function of patients with late-stage liver cirrhosis by application of vector myocardial strain and strain rate imaging (VSI),and discuss the changes of the regional left ventricular systolic function of patients with late-stage liver cirrhosis. Methods The longitudinal peak systolic strain rates(L-SRs),radial peak systolic strain rates(R-SRs) and circumferential peak systolic velocity(C-Vs) in 30  patients with late-stage liver cirrhosis (patient group) and 30 cases of age-matched normal persons (control group) were detected by VSI technology. Results The  L-SRs of mid-anteroseptal,apical-anterior and apical-septal in patient group were reduced compared with control group (P<0.05);the R-SRs of mid-anteroseptal,apical-anterior and apical-septal in patient group were reduced compared with control group (P<0.05);the C-Vs of mid-anterior and mid-anteroseptal in the cirrhosis group was reduced compared with control group (P<0.05). Conclusion The regional left ventricular systolic function of patients with late-stage liver cirrhosis has already reduced before the global left ventricular systolic function has not significantly affected.
