Myocardial performance index (MPI), or Tei index, is a Doppler echocardiographic parameter defined as the sum of the isovolumic contraction and relaxation times divided by the ejection time. It is considered a reliable parameter for global left ventricular function. However, the interpretation of this index is not fully clear in diastolic dysfunction. We measured MPI in a pressure-overload model of rats with severe diastolic with or without systolic dysfunction and examined its usefulness as a parameter for cardiac function in a hypertensive heart failure model.
