The application of tissue Doppler imaging (TDI) has shown remarkable growth in clinical practice during the past few years, especially, in risk stratification of patients with coronary heart disease or heart failure (systolic and diastolic). Myocardial performance index (MPI) is a Doppler echocardiographic parameter defined as the sum of the isovolemic contraction and relaxation times divided by the ejection time. It is considered as a reliable parameter to assess global left ventricular function. Cardiac time intervals and MPI have also been found as new applications in diagnosing cardiotoxicity from chemotherapy, COPD, valvular heart disease, pulmonary hypertension and endocrinopathies. © 2010 SIMI.

Abstract
The application of tissue Doppler imaging (TDI) has shown remarkable growth in clinical practice during the past few years, especially, in risk stratification of patients with coronary heart disease or heart failure (systolic and diastolic). Myocardial performance index (MPI) is a Doppler echocardiographic parameter defined as the sum of the isovolemic contraction and relaxation times divided by the ejection time. It is considered as a reliable parameter to assess global left ventricular function. Cardiac time intervals and MPI have also been found as new applications in diagnosing cardiotoxicity from chemotherapy, COPD, valvular heart disease, pulmonary hypertension and endocrinopathies. © 2010 SIMI.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
