Left Ventricle Myocardial Performance Index Derived Either By Conventional Method or Mitral Annulus Tissue-Doppler: A Comparison Study in Healthy Subjects and Subjects with Heart Failure

We performed a study in healthy adults and in patients with congestive heart failure to investigate the clinical agreement between MPI measured conventionally and by PW-TD of the mitral annulus. We found mild agreement between MPI measured by the conventional method and by PW-TD. Both methods had high diagnostic accuracy for CHF. PW-TD method requires a higher MPI cut-point for best diagnostic accuracy.
