- W2373816701 abstract "Objective To investigate the prognostic value of regional myocardial performance index(rMPI) calculated by tissue velocity imaging(TVI) on left ventricular systolic function. Methods Fifteen healthy individuals and eighteen patients with congestive heart failure were!included. After acquiring apical two-chamber, four-chamber and long-axis view two-dimensional TVI, rMPI was calculated at basal and middle left ventricle levels as well as at mitral annulus level in each of the left ventricular walls(anterior, anterior septal, posterior septal, inferior, posterior and lateral). Myocardium performance index(MPI) was calculated by mitral inflow and left ventricular outflow Doppler profiles. Left ventricular ejection fraction(LVEF) was calculated by modified Simpson′s method. Results rMPI and MPI were significantly higher in patients with congestive heart failure than in healthy individuals(P(0.05)). rMPI, especially the mean rMPI of mitral annulus had a good correlation with MPI(r(0.50), P(0.01)) but had a negative correction with LVEF (r(-0.75), P(0.01)). Conclusions rMPI measured by TVI has a prognostic value in assessment of left ventricular systolic function in patients with heart failure." @default.
