TI  - Comparison of myocardial performance index versus ratio of isovolumic contraction 
      time/ejection time in left ventricular systolic dysfunction.
PG  - 1061-7
AB  - Myocardial performance index (MPI) has been regarded as an important parameter in 
      the evaluation of ventricular systolic function in congestive heart failure. This 
      study was designed to investigate the relationship between the ratio of 
      isovolumic contraction time/left ventricular ejection time (IVCT/LVET), MPI, and 
      LV systolic function. A total of 43 patients (patient group) with LV ejection 
      fractions (LVEFs) <55% were compared with 43 patients (control group) with LVEF 
      values >or=55%. LVEF was measured in all cases by 2-dimensional echocardiography 
      via the modified Simpson method. Isovolumic relaxation time (IVRT), IVCT, LVET, 
      ratio of IVCT/LVET, and MPI ([IVRT+IVCT]/LVET) were measured via Doppler 
      echocardiography. The mean value for IVCT was found to be significantly higher 
      (P<.001) and concomitant mean LVET value significantly lower (P=.027) in the 
      patient group. Similarly, the mean value of MPI and the ratio of IVCT/LVET were 
      found to be significantly higher (P<.001 for both) in the patient group. The 
      value of the ratio of IVCT/LVET was found to have a significant negative 
      correlation with the value of LVEF (r=-.947; P<.001) and a significant positive 
      correlation with the value of MPI (r=.796; P<.001). The study reported here 
      clearly demonstrates the noninferiority of the ratio of IVCT/LVET to MPI and the 
      possibility of its substitution for MPI in the evaluation of LV systolic 
      function.
