AimThe myocardial performance index (MPI), or Tei index, has been shown to be useful in the assessment of global performance. There are few invasive data however, which examine its load dependence sensitivity acute changes contractile function. The purpose this study was therefore formally effect clinically relevant these parameters an animal model.
